Experiencing Aerobic Limitation

I spent a rainy bank holiday morning sprinting up a nearby hill repeatedly. It’s a key part of getting faster and one that I’ve not done since last summer. Having woken at 6am, I grabbed a bowl of cereal then did the crossword while breakfast digested. About 8:15am, I headed out the door and there was light rain falling. The session I had in mind is not big – a 15 minute warm-up run, 5 mins of drills to help the mobility, the main session of 10 hill sprints and then a ten minute warmdown. But it is time-consuming because each sprint is followed by three minutes of recovery. In the end, it took over an hour to complete. What interested me is what the session told me about how to train for distance running.

Setting off on my warm-up it took three minutes for my body to crank the pace up and reach eight minute miling. My route is a mixture of ups and downs such that, by the end of the first mile, I’d been hitting sub-6 pace on a steeper downhill stretch – 7min38 popped up on my watch. The second mile came in at 7min04 and then I tacked on another thirty seconds back to home. What surprised me was how relatively hard I was finding it. My breathing was beginning to huff and puff like I was running a parkrun and my heart-rate reached 160bpm at the end. All in all, I was glad when I finished my warm-up and could walk back round the corner to do drills.

With the rain falling steadily and knowing I’d be standing around between the hill efforts, I elected to keep the drills short. Just one repetition of each drill taking 15 seconds and then a stride back to my start position with around 30s time to recover before the next. The stride reinforces what I’m programming as well as warming the legs up for the quicker, more violent efforts up the hill. Once again, by the end of these I was puffing and my heart-rate had steadily increased to 155bpm; each subsequent effort building the heart-rate higher than the one before.

Finally I was ready. I walked to the base of the hill and then spent a few minutes chatting with an old chap about goings on. The important thing about hill sprints is to attempt them with fresh legs so I didn’t mind an extra few minutes spent conversing. Hills sprints want to get maximum effort from the muscles which is why they only last seconds and then you get a nice long recovery. The short timeframe allows your ATP-PC energy system to be the key producer of energy while the long recovery ensures it has recharged.

The first effort I sprinted up the hill and my legs were turning over so smoothly. I was barely breathing, it was how I’d feel if I was out for a jog. Then I started to walk back down the hill and the oxygen debt kicked in and within fifteen seconds my heart-rate had reached 139bpm having started down at 90bpm. The second effort felt a little harder on the breathing especially afterwards and my heart-rate reached 143bpm. By the time I’d ambled back downhill to my starting place, it was back to 114bpm and I was feeling okay. After that my heart-rate never got out into the 140s again. Sometimes the oxygen debt after each effort resulted in very quick gasps for breath yet it didn’t take long to be back to normal. As the sprints went on they got a little slower, this is unsurprising because the muscles are beginning to fatigue and they can’t power getting as far up the hill.

After my 10th and final effort, I walked down until one minute had elapsed then began a warmdown run. My legs felt like they were springing along yet the pace was barely quicker than nine minute miling.


What intrigued me about this session was how two such different ways of training – the warm-up and sprints both taxed me in different ways. The warm-up pace picked up gradually to be a little quicker than seven minute miling where I still had room to run faster. Yet it would have been hard to stay running like this for an extended period of time. By contrast the hill sprints which are an absolute blast of maximal energy felt so much easier.

According to the wisdom of heart-rate training I could have done sprints all day long as I maxed out at whereas my warm-up reached 160bpm. Yet I know that wouldn’t be a good idea – no-one would do that, neither a sprinter or distance runner.  It highlights one of the problems of heart-rate training.

What really came home to me from the warm-up is that the thing limiting my distance running is not speed related. This is what I experienced when I first began parkrunning a decade and more ago. Every week I would run and feel there was more available in the tank yet not understand what was stopping me.

The limitation was not one of being able to run very fast for a short time as it is with anaerobic limitation, it was one of being able to run fast for a relatively long time. That’s where aerobic development is required. It took me the next five years to really begin unravelling this conundrum in detail. I read many books which talk about it needing to be done yet it’s not until you viscerally experience it that it becomes clear what is going on.

I meet many runners who haven’t yet had this realisation that being able to run fast 200s, 300s, 400s is not necessarily going to turn them into a faster distance runner. Sometimes it does but more often than not it’s about building speed through good distance training.

Maybe this is something I can help you with? Not everybody wants to be coached for a race, sometimes they simply need a training review. Understanding what they need to do next to get to the next level – is it speed or endurance they should work on.

Update on my 800m training – Apr 2023

April has been a quiet month. Entering it I had high hopes of recording a decent time at Bournemouth Bay 1/2M but those were trashed when I ran three minutes slower than last year. I tapered better this year and my legs felt fresher on the day but, come the run it was a gradual slide with the first 2-3 miles coming in at just under seven minute miles. From mile five onwards the pace dropped to 7:25 and worse. I just had nothing and have easily done better runs in training. I documented last month how I ran six miles in 42-mins in training.

What was strange was how low my heart-rate was throughout the run. It ended up averaging 149bpm which when I consider I do Steady runs in the low 150s was very out of place. What it does go to prove is how little use a heart-rate monitor can be.

I took five days off after the half (no running at all) then went to Poole parkrun and ran 20:57. Both my calves and glutes were sore from it and I had a very slow, dreary Sunday 10-mile run. I ran thirty minutes each day through the following week and returned to Poole parkrun knocking my time down to 20:39. The following week was the same routine, a slightly faster but still drudgy ten mile run then thirty minutes each day. This resulted in a 20:17 parkrun! Three weeks of easy running, no speedwork and my racing simply got faster by forty seconds.

It now seems clear that I’d fatigued my legs too much in training. When I look back I’ve been doing fifty mile weeks since last summer and training hard in the week. The heart-rate monitor numbers were correct but the monitor itself can’t tell you how fatigued you are.


My overall feeling though is one of disillusionment – I’m simply not cut out for distance running. When I compare my training to others, I simply don’t get the results from training that they achieve off much less. I train hard with all sorts of different sessions but ultimately I’m physically not cut out for long distances.

I’ve known this for a while, it’s why I started training for the 800m. Thus far I haven’t really worked on developing my speed to a high level because I’ve been trying to keep the aerobic side in balance. As I’ve written in the Ageing series, the best male sprinters of my age are running under 11 seconds for 100m, 22s for 200m and 50s for 400m. While I’ve not gone all-out at any of these I’d be surprised if I could crack 14s for 100m, 30s for 200m or 1min15 for 400m – that’s just too far down and a gap I need to close up. It’s not because I’m not capable, it’s because I haven’t trained for it in years.

I’m beginning to conclude this has been where I’m going wrong. The first two iterations of training I followed JackD’s plan as he is a proven coach. It didn’t really help me. Last year I began hill training using a progression from Steve Magness’ The Science of Running and I felt this made a difference despite only doing one weekly session for three months.

I’m torn between entirely given up on the distance work until I’m notably nearer to the age-group records or trying to keep the two things in balance. All I know is when I started running seriously a decade ago, I was probably quicker on the speed side. I have little objective proof of this but my legs were much bigger and stronger. I was quickly able to build some of my best times at parkrun, 10K and half marathon on lower mileage than I’ve been doing recently because I had the speed first.


This summer’s plan is to repeat what I did last April / May / June. I combined Steve Magness’ hill sprints on a Monday with Jack Daniels’ 800m training plan on Wednesdays and Fridays. I lasted about nine weeks before I could see I’d peaked and my aerobic fitness was declining.

This year I’m intending to do the same but with some changes. Where I previously followed Jack’s plan for runners covering 30-40mpw, this year I’m downgrading to the 20-30mpw plan with shorter recovery and long runs. Actually Jack’s long run has always lasted only about an hour on these plans but I always did something in the 1hr30-40 range in an attempt to keep my aerobic system up.

The other change I’m going to make, as I’m not doing a time trial prior to starting training, is to be conservative on my numbers. I’m based my training level on my half marathon and fastest parkrun which basically have me running at the level of a 2:36 800m runner. It’s not that fast but I’m aiming to keep my legs fresher this year through less intensity and lower volume of training. Again this 2:36 start point is why I don’t think I’ve got the speedside sorted. It really isn’t that fast given how in shape and athletic I am. I just haven’t trained for speed enough in years.


I resumed faster training in the final week of April. I did 6x8sec hill sprints on Monday which felt great and I loved despite blowing hard at the end of each effort. On Wednesday I did 6x200m with 200m jog recovery aiming for 43s, they avg’ed 40.4sec. On Friday my legs were perking up and I repeated the session, this time with eight efforts, and they avg’ed 39.6sec. My body felt like it was hitting new territory. Or at least territory which it hasn’t been to in a long time. My breathing was gasping in the final efforts. I’ve been there before but this felt different for some inexplicable reason.

Before each of the workouts, I’ve been doing drills and strides to help warm-up and ingrain good form. I began these eighteen months ago and change has been gradual, notably beginning to kick in at the start of the year when I was doing my last block of short intervals. This explains why my glutes and calves hurt after the half marathon. It was the longest sustained effort I’ve done using that running form and therefore being powered by those muscles. My stride seems to be lengthening and when I begin an effort I can hit higher cadences than usual. This all suggests I can get quicker and build my speed up to the levels I desire.

Update on my 800m training – Feb / Mar 2023

Winter training isn’t fun if the weather isn’t amenable to it. And it hasn’t been. We seem to have had windy, cloudy days through Feb and March. Fortunately not much rain although that doesn’t particularly bother me. But when you’re trying to do longer intervals or steady runs and track improvement week-to-week, windy is frustrating.

I came into these months looking to build endurance ready for a half marathon on April 2nd. I’m generally very pleased with how this training block has turned out although, as they say, the proof will be in the pudding. Let’s see how the actual race goes.

I did the race last year scraping under 1hr34 which was my fastest half marathon in almost ten years. While results-wise that is pleasing, I didn’t run my best race, my best running was left in training. On race day my legs had gone. They were heavy and lethargic and I couldn’t push any faster than 6:40/mile at any point. This despite having averaged 6:32/mile for three two-mile efforts on March 15th. The aim was to avoid that this year.

I went with the same training plan as last year but started the long interval build-up two weeks earlier to give myself more time for a longer taper. On Fridays I did my Steady hour run on the flats of the beach promenade whereas last year I ran a hilly local route. The knock-on of this latter point, as I shall explain later, is I ran quicker parkruns immediately the day after.


Below in the tables are the sessions I ran last year and this. You can see on the first week my mile repeats are very similar – both averaging around 6:55/mile with the first mile quick and then a slide as the endurance ebbs away. In the following weeks the body gets better at stamina work – holding a fast pace for longer and the efforts improve.

While the general improvement seen is similar, this year’s numbers were behind last year’s. While the weather wasn’t perfect, I can’t blame that. There was something else at work. What these numbers don’t show is the effort being put in. While I could add heart-rate data, that doesn’t really show it either.  This year my heart-rate has generally been 2-3 beats lower on these efforts which chimes with the slightly slower pace.

What’s not revealed is the effort I was putting in. When I ran last year’s effort, I would overcook them and go anaerobic. Gasping for breath in latter efforts and pushing hard to keep the pace up. I might have expected that effort to show up in higher max heart-rates, if not the average, but it doesn’t which is why I’ve moved away from gadget / data-driven training. This year I deliberately tried to keep my pace under control by focusing on my breathing and not pushing my self too hard. I still pushed hard but not too hard.

As a sidenote, it’s worth explaining what happened in the session on 28th February. The local roads were being dug up to install higher speed broadband cable so I went to the beach. I had hopes this would be quick as it’s on the flat but it was windy. Even so I set it up to have the benefit of the wind on two of my three efforts but my legs had nothing. On reflection, I was suffering a VO2 lull so I just tried to get through it as best I could. Trouble is, I also misprogrammed my watch and instead of having a 0.5mile recovery, the next effort started after 0.05mile which had only taken about thirty seconds to jog! I had to reprogramme the session on the fly and guesstimate the recovery. All in all it was, what we technically call, a balls-up. It would have been easy to get downhearted about the day’s numbers, but after all these years of running I have learned it is just part of the process.

Fridays and parkruns

I consider the hour long Friday sessions to be an important part of building endurance. They highlight where aerobic speed is at. This year’s sessions weren’t as fast as other years but what was incredible was going to parkrun the following day and running decent times. Last year my parkrun was around 24-25 minutes following a Steady run; in 2019 it was more like 27-28mins. That said, I think last year’s hilly route took more out of my legs but perhaps also provided the extra ounce of speed I was seeing in the long intervals.

26-Mar7½ (fasted)54:597:236:56Tapering

One reason why I’ve moved away from data-driven training is that some of my endurance days are coming in at relatively low heart-rates yet I’m not racing significantly quicker. My 21:19 at Poole averaged 6:50/mile at a heart-rate of 147bpm – well below the 152HR I consider to be the top of my pure aerobic for a Steady run. I’m hopeful these numbers point to capacity for getting quicker in the summer but I think they actually point to simply having better endurance which is not that important in a shorter distance race especially the 800m which I’m targeting.

Recovery

The notable improvement in my running seems to have come in recovery. While not every session has been as hoped for, my average speed through the week has been improving. Being able to run fast on Tuesday, on Friday, on Saturday and then sub-8 on my long runs is a far cry from where I was a few years back. I could barely run 8-miles at a sub-8 pace once in a week. On top of the effort days, my recoveries have generally been approaching or faster than 8min/mile – a few years ago these would have been well over 9min/mile.

I think this has been the route of the problem. Running easy runs too fast – it is a perennial problem among runners – I can screw it up as well as anyone! Although the runs are manageable and haven’t been causing me any pain, I think they have been creating muscle damage and fatigue. That explains why I can’t run faster in actual workouts. Again, the data isn’t good enough – my heart-rates on runs have been low enough to be classed as recovery but the tech can’t measure muscle damage directly. We can only infer it from how training is going.

In the middle of March I made a decision to go slower on my recovery runs and I think it was the right one. Along with the taper my legs have begun to perk up.

The final workout

I did my final workout on Tuesday. I call it a workout but it wasn’t there for training effect, only to keep the legs reminded of what’s coming up. I did a 30-min Steady run with a half mile effort dropped in after two miles. The two mile warm-up came in at 7:10 pace and then the half mile was unexpectedly quick. It came in at three mins exactly – 6min/mile pace. I did push it a little towards the end but considering I went straight into it off the warmup I was pleased with it. Thinking back to December 2020 and my first 800m time trial that’s essentially what I ran that day – except I had fresh legs and my lungs burned for an hour afterwards. This time I jogged home and got on with life

Half marathon on Sunday April 2nd

The rest of the week has been some easy 30-min jogs and rest days. I’m hoping the 800 wasn’t too much of a shock for the legs. If it was, it’s probably not going to go well and I’ll be left rueing it but at least knowing I’m set up for excellent spring training.

I’m not sure what to expect on Sunday. I believe my stamina is better than last year and therefore I will record a better time. Last year I struggled because of the misjudged taper, this year I’ve hopefully corrected that. The weather forecast is decent – sunny with 7-8mph wind – I probably can’t ask for much more than that. Let’s see what happens.

Coaching a first time marathoner

I opened the Whatsapp message which she’d sent after finishing. “Tbh the whole thing felt easy” it read. It had taken 4hr35 to run the cobbled streets of Rome and not only was it her first marathon, she only started training in November and never ran further than 17½ miles (28km). Yet reaching that distance on race day she opened the jets and picked up her pace, running the final kilometres quicker than a 4hr15 marathoner and throwing in a 5:37 kilometre to the finish line. That is not how most marathoners, especially at the slower end of the field get through their first marathon.

Last September my daughter asked me whether she had enough time to train for Rome marathon. I said “Yes” and wrote her a training plan. She responded by not following it and barely doing any running! After six weeks her biggest week had only covered 12miles and a longest run of 1hr16. It was not a great start. It was the arrival of a new flatmate, with whom she could go running, which kickstarted things; I rewrote the plan and from there on she trained diligently for 4½ months to experience a great marathon and finish in the top half of women finishers.


When she signed up, she was barely running, just thirty miles in the preceding six months. In the past she had done occasional morning runs, pushing all-out to achieve around a 27-min 5K, but this needed a different approach. The training plan I gave her built up to running five times per week and peaking at 35 miles and needing a commitment of up to six hours. Apart from when it was raining, I never heard any complaints or desire for training to be over. All in all, I’m really pleased that my coaching and her hard work resulted in a successful first marathon.

With so little running done prior to starting I knew there were some challenges regarding how to prioritise training. There were a number of things needing to be done.

– Get her used to do high volumes of weekly running – I wanted her to run five days per week and train for 5-6 hours. After all if you can’t run five hours in a week, how can you expect to run it in one race?

– There was the all-important question of how to train a slower runner for the distance on the day? As I wrote in The 20-mile myth beginners are wedded to the idea that because committed runners of the past always trained to reach twenty miles they have to as well. Yet the training benefits are highly questionable and I’ve met many of these slower runners whose marathon training becomes a slog because they spend consecutive cold, wet Sundays in February out for four hours or more. On race day they end up walking anyway and taking five hours.

My decision was I would train her by time and the longest run would be 3hr15. But some of these long runs were to be preceded by a run the day before. This would take the total time spent running on a weekend to four hours and closer to her expected race time. It would have to be enough.

– Ideally I wanted to improve her speed because that would then trickle down to her other paces. It’s obvious if you can run a faster easy pace then the long run will cover more ground.

– The last three weeks of training would be taken up by a taper. By necessity this would cut into the weeks available to make progress through training.

– The final factor to account for was the non-running parts of her life. We had Christmas and New Year coming up and currently being based in Italy she was going to do some travelling as well as university exams. I managed to accommodate these around the training with only a few things moved around.


Once training began properly we built the base in November and December. By New Year I was satisfied she could do 5+ hours running every week without injury or illness coming up. To this point, every run had been at an easy pace of 11 minute miles or slower. She didn’t particularly like it as she prefers going out quickly but did what was asked.

Her first two hour long run was reached at the start of December and we built on from there in small manageable chunks so that by mid-January, she was able to do her first three hour run. This was followed by three more runs of three hours including a 3hr15 run which was the longest at 17½ miles, or two-thirds of the marathon distance.

With the base built, I introduced faster midweek runs lasting up to an hour. Initially at a 10:30/mile pace, as the weeks went by the runs quickened up to be as fast as 9:30/mile. These steady runs continued up until the taper began.

In late January I took her to Christchurch 10K – her first official race. I wanted her to get an idea of what a race is like. How much standing around there is, what it’s like to run with other people. Given her best 5K was around 27 minutes, I expected her to run 57-58 minutes. I was amazed when she finished in under 55 minutes – an 8:45/mile pace which was much faster than anything she’d been training at. It was a great result and informed me of the paces required for the rest of her training. With two months to go to race day it was now all about building stamina and endurance for the big day.

On race day, she was aiming to break 4hr30. To keep it simple, I gave instructions to pace at 6:20/km which is running three kilometres every nineteen minutes – nice simple maths. This would bring her in for a time of 4hr27. From the 10K race I knew this was within her capabilities, probably even faster. She was accompanied by her flatmate and they paced themselves consistently except they used a phone to measure the distance rather than going with the race markers. Consequently they were running 10-15sec/km too slow and went through halfway on pace for a 4hr40 marathon. Soon after her flatmate’s leg began to hurt so they separated at 28km and my daughter sped up running to the end at the pace of a 4hr18 marathoner. Not bad considering she’d never run past 28km in training!! Her flatmate, reportedly a 38-min 10K runner but who hadn’t followed any of my training plan, limped home in over five hours.

Later another Whatsapp said “The whole time I could talk easily and the time went very quickly. At no point did it feel long”.

Not many first time marathoners have as an experience as good as this. It all comes down to well-structured training, putting in the miles and running at the right paces. The postrace Whatsapp stated “Didn’t feel hard. Harder training sessions”. And there’s no doubt she put together some good training sessions. Come marathon day, after the taper, it all came together.

The highest volume of training came in January and February where it was eight consecutive weeks averaging around six hours. The monthly mileage was September 10miles, October 30miles, November 76miles, December 109miles, January 132miles, February 133miles and March 81miles including the marathon. Those figures in the middle may sound big and they are, but when carefully built up to and interspersed with lots of easy miles they accumulate without wearing you down. That was a focus of my coaching to maintain motivation and never let it feel like it was becoming too much.

There is no way to run a decent, comfortable marathon without doing the training. I’ve tried and it didn’t go well. Equally it’s possible to do heaps of training and still run a poor one. What I offer to runners is the knowledge of how to structure training optimally to give them a good shot at success on race day.

Short term loss for long term gain

Growing up I drank my tea with sugar. It was a lovely sweet taste. Someone asked if I wanted a cuppa, I said “Yes” (being a teenager there was rarely any sign of a Please although there was usually a Thank-you when it was delivered) and it got drank quickly.

When I left education and started work in computing, we had tea and coffee rounds where seemingly every hour someone in the department would be wandering off to the vending machine to get them in for the team. I eventually dropped out of the rounds because I wanted to drink on my own schedule not someone else’s. I got a sense it was frowned upon because it was a rejection of their generosity and I was setting myself up as a non-team player but on reflection, I don’t care. I realise I was listening to my body. I was drinking tea when I felt thirsty not because someone was forcing it on me.

About eighteen months into this I realised I was drinking seven or eight cups per day. They were only small vending cups yet I knew that with each cup I was putting unnecessary sugar into my body. Multiply those eight cups per day across the week, across the year and on through a lifetime and it was probably mounting up for tooth rot and unnecessary calories. These were the days long before anyone worried about an obesity crisis or dangers of too much sugar. I suppose I was ahead of the curve!

I made a rational decision – I would stop drinking tea with sugar to save myself from all those extra lifetime calories. And so I went cold turkey and it was horrible. The tea became tasteless, like chewing on cardboard or paper. And being cheap, 7p per plastic cup tea, it was probably low quality anyway but I persevered. For months, drinking tea became a joyless experience. Then one day, either by accident or on purpose I had a cup with sugar. Ugh. It tasted horrible too. Far too sweet.  So I was now between a rock and a hard place – tea without sugar tasted horrible, tea with it tasted horrible. Either way forward or backward was going through pain. In the end, it was about a year before I started to enjoy drinking tea again but now, looking back from thirty-odd years in the future it was a good decision given how many cups of tea I still drink each day.


Recently I’ve been working on building my shoulder muscles. I noticed last year my left pectoral muscle is beautifully square whereas the right pec has a slight curve to it. A little wiggling of my right shoulder forward and backward identified the underlying root cause of the aesthetic displeasure. There is a slouching, slumping of the right shoulder which when forward causes the pec to sag slightly.

While this is not devastatingly obvious or problematic, like the tea in sugar, I feel it’s worth correcting for when I’m older. Old people often become round shouldered and then hunched which then causes further issues. I already notice sometimes when I am sat typing or driving in the car that the right shoulder is slumping forward and it feels ungainly and may even ache a little. Getting my pec square is a goal not for the aesthetic but because it will indicate the shoulder muscles are working correctly to keep it in position. Of course, unlike the tea drinking, lifting some weights twice per week is hardly painful or something I couldn’t stop.


My training philosophy is that, while everybody is subtly different, each muscle in the body works in a certain way and for a certain purpose. If the shoulder muscles have got used to sagging then, if I can easily correct them with a bit of strength work and conscious repositioning then going to be worth it. In time they will start to hold the joint correctly and strengthen themselves.

It’s easy for muscles to weaken and stop working and the body to compensate with other muscles which aren’t best for the job. A simple example is lifting a heavy object, the best way to do it is by bending the knees and using the leg muscles whereas poor lifting technique has people bending over at the waist and straining their back muscles.

It’s the same with running. We have an array of muscles in our lower bodies which contribute to movement. Some runners power their runs predominantly using their glutes, others use the thighs while some tap into their hamstrings or calves. While my training approach is not interesting in changing form to look good, I do believe it’s worth spending a little time each week to try and improve form through drills and strength work.

My belief is twofold. By using the right muscles for the right job, you get maximum power applied when you are running. If the wrong muscles are doing the job, they aren’t going to be as powerful at it. Secondly, they may already be fatigued when they are asked to do the things they are good at which means you get less out of them and it might even lead to injury. At best using the wrong muscles is a power leak. At worst, you’re unnecessarily fatiguing muscles that aren’t then able to handle what you want them to do. You’re not getting the best out of yourself. Bear in mind, I’m not prescriptive about what is good or bad form, only that we need to get the right muscles firing in the right sequence to maximise our own physiology.

But change takes time and with a complicated action like running, where there are many moving parts, adopting new form doesn’t necessarily come quickly. Small improvements in one area can lead to a change in another area that may or may not be desirable. If change was easy, top class runners would all have amazing form but they don’t.

When we start getting the right muscles to fire correctly they may be too weak to carry the training load we’d previously reached. We may have to run slower or train a little less until they strengthen up enough. It takes conscious effort and a willingness to accept a short-term loss for a long term gain that will hopefully last a lifetime. Just like when I gave up drinking tea with sugar.

Slow Burn by Stu Mittleman

I’m meeting up soon with an old friend who I haven’t seen since 2013. It was then he lent me his copy of Stu Mittleman’s book Slow Burn – Slow Down, Burn Fat and Unlock the Energy Within and I’ve realised it’s now time to return it! Having taken it off the shelf in readiness for our meet up, I was reminded of its content which credits Phil Maffetone for helping Mittleman’s training.

When I first read the book almost ten years ago, the ideas within it weren’t entirely new but they were still a puzzle as to how they fitted into the picture of my training to improve it. Just like John Douillard’s book Body, Mind and Sport and Maffetone’s Big Book of Endurance Training the ideas of unlimited energy and running slower to get faster seemed so promising. It was the following summer when I tried MAF training with gusto and saw that it simply didn’t work as I hoped.

Stu Mittleman is not a household name but fortunately he gives us his credentials early on. The first marathon he ran was Boston in 1977. In those days you needed a sub-3 time to qualify so he trained for a couple of weeks then ran a 2hr46 marathon (6:20/mile)!  Instantly he’s cluing us into his endurance capabilities. The book later tells us about how we was a champion ultrarunner who set a world record by running 1,000 miles in 11 days, 20 hours, 36min and 50 seconds. About how he ran almost 600 miles in six days but also how this was preceded by a struggle with injuries. It was Phil Maffetone who fixed him and taught him how to train using his age-related heart-rate formula. It’s fair to say some of what Mittleman wrote in this book, published in 2001, is based on Maffetone’s wisdom.

It’s a very readable book divided into three sections – how to THINK, TRAIN and EAT for the distance.  Each section has short chapters giving you time to digest what they have to say before you move on. There’s a lot of good information to think about.

How to THINK for the distance

Mittleman explains shifting from a goal-oriented approach to a process-oriented one. He gives the example of a group of twenty-six first time marathoners he had to train for the New York marathon in only nine weeks. Instead of focusing on finishing, he got them to experience (and therefore enjoy) the day by focusing on the twenty six aid stations positioned at each mile. He also explains how he approaches training day-by-day and how to enjoy runs.

To a coach or anyone who has worked in project management the idea of breaking a big goal into a series of intermediate steps of milestones is second nature. Of course twenty-plus years ago, when the book was written, fewer people were clued up to this approach; and performance, times, goals and Personal Bests still dominated their thoughts. Today the culture of marathons has changed and it is now common to have complete novices running marathons in 5-6 hours and not worrying about times.

How to TRAIN for the distance

How to TRAIN is the section that most interested me to read. I glossed over the initial chapters which focus on listening to your body by muscle testing / applied kinesiology, use of acupressure or reflex points and buying the right shoes for your feet. I rarely getting injuries and since the book was written much more information has become available about which shoes to buy as well as instore gait analysis etc.

Where How to Train gets interesting is in its explanations on learning to breathe deeper and giving you metaphors for good running form. I already knew how to breathe deep from Body, Mind and Sport and while the metaphors themselves are nothing I’ve ever applied apart; the idea of them is great. The best metaphor is the idea of “rollercoastering the hills” i.e. slow down as you run up them and speed up again on the down.

Discussion then moves into an explanation of fat-burning vs sugar-burning and its effects on the body. This is much the same ideas Phil Maffetone puts forward about how fat-burning is the way to stay healthy while sugar-burning leads to stress, illness and injuries. As I explained in the MAF Training Review series the general principle is right but it has been oversimplified into inaccuracy. Mittleman is a little more moderated stating on page 120 “You’ll lose the point if you reduce [it] to sugar is bad and fat is good”. As we’ll see in his heart-rate training system learning to burn fat dominates his training system but he does allow you to do faster work each week.

Mittleman HR Training system

Like Maffetone, Mittleman’s system begins by subtracting your age from 180. As I stated in my MAF series there is no scientific connection between age and how the body burns fat or sugar so this system is off to a negative start from the beginning.

Nonetheless it breaks training into three zones termed Mostly Aerobic Pace (MAP), Mostly Efficient Pace (MEP), Speedy Anaerobic Pace (SAP). The top of the MEP is 180-age, the bottom is 10 beats lower. The MAP zone is the 20 beats below the MEP zone. The SAP zone is the 20 beats above it.  Like the Maffetone formula, you are then allowed some adjustments depending on your experience and health. Finally Mittleman says to fine tune the zones based on how you feel in them. This final step seems to undo the point of using the formula.

Let’s work through for me as a 50-year-old runner:

180 – 50 = 130 MEP upper limit, so MEP lower limit is 10 lower at 120bpm.

I can raise it by 10 beats because I’m an experienced endurance athlete:

  • MEP range becomes 130-140bpm
  • MAP is there 110-130
  • SAP is 140-160

On paper these sound okay and Mittleman then details three levels of training for casual, recreational runners through to the more competitive. In his top level programme you run 3 MAPs, 2 MEPs, 1 SAP each week. This doesn’t seem like a bad mix.

The SAP training sessions are quite light volume (in my opinion) involving intervals lasting from one-to-five minutes. On the first week you total only seven minutes in the SAP zone and in week twelve it maxes out at four intervals of five minutes – twenty minutes worth. Then he strongly recommends taking a prolonged break of three months from SAP workouts; so only doing two blocks per year.

My training compared

The setup of my sessions for a week looks similar – I typically do three harder session each week and four recovery runs. One of my harder sessions is a long run which is not highly intense and would be the equivalent of an upper MEP / lower SAP session. The other two workout days would more likely involve entering the SAP and even going above it if I’m in a phase of shorter intervals. On recovery runs, when my legs are very depleted I struggle to get out of the MAP (sub-130) zone but more usually I’m hitting 130-140 thereby including some MAP work.

In “When You Need MAF” I analysed a typical training week for myself and looking at it again with these zones I find I’m nowhere close to what Mittleman is advocating. On the week in question I spent only 40mins in MAP, 2hr47 in MEP, 2hr55 in SAP and 22mins above SAP. When I look closer at his SAP programme I find I do more in one week than the whole twelve week’s programme (2hr27!)

The most significant line in the book is on page 195 “While running in my MEP target zone of 145-155, I reached the point where I could maintain a steady 5:45 per mile. I wasn’t straining or uncomfortable.”  This is the sort of heart-rate I use on my twice-weekly Steady runs and sometimes approach on my long runs. While I don’t have the endurance ability of Stu Mittleman, I can run 7:00 per mile at heart-rates in this range with the same effortless feel.

I’ve been following my regime for months and continue to use it while making progress and seeing my pace vs heart-rate improve. I’ve yet to pick up any of the injuries or illness that seem to be put forward as a reason to use age-related heartrate training. It’s hard to see what benefit I would derive from running slower more often and barely doing any training at threshold or faster.

How to EAT for the distance

I have to admit I didn’t make it far into this section. I read a book on nutrition many years ago which I tried to follow but any running books pushing me towards a diet that cuts out sugar doesn’t appeal to me. My diet is dominated by carbohydrates and the suggestion that I cut these out leaves me wondering what I’d eat as I don’t like cooking and I don’t eat a lot of fruit and vegetables. That said, I don’t eat sweets or crisps although there’s usually room for a slice of fruitcake or a flapjack!

I have always eaten to my hunger and while this is not a perfect strategy, I’m fit and healthy. What I have noticed is once I finally figured out how to do endurance training, I stopped getting hungry, I even stopped wanting cake. While my diet is still dominated by carbs – cereal, bagels, bananas, rice, pasta, bread and potatoes – I only eat when I feel hungry. Often I don’t feel hungry even after coming back from a long run.

What I now understand is how I used to train depleted my muscles of their glycogen and set me up to crave carbs to replenish the stores. As you improve at endurance training two things happen; firstly you improve the aerobic quality of the intermediate fast-twitch so that they still use glycogen but much more efficiently and secondly you tend to stop doing sessions that use the fast-twitch muscles which are fuelled by glycogen.

Let’s return to the biography I gave in the beginning. Mittleman was already endurance-trained and capable of running a 2hr46 marathon when his journey began. He could run 6:20/mile off little training and later states he can run 5:45 at 145-155HR in his MEP zone. Mostly Efficient relates to what I see as aerobic glycolysis. It still uses sugar but efficiently as the zone name suggests.

He states on page 189 that he’s happy running at 12min/mile pace for his MAP run three days per week and that he was once asked by Runners World why he ran twenty miles per day to which he answered it’s all he had time for! That’s the sort of thing you expect from ultrarunners who are interested in running for five hours or more but it’s no route to success over shorter distances. Ultra training for long distances requires many hours and miles of training and it can only be done at slow paces or the body will break down.

So we see he’s recommending eating strategies that are appropriate to his event. What we have to remember is the context of Mittleman’s running career. He is a champion ultrarunner. He is out for hours on his races and no doubt trains for hours each week. The average pace of his 100-mile world record is 7:44/mile and while that might sound fast to some runners, it’s not in the context of shorter races. I’d expect that to be a heart-rate of around 115bpm. There’s no doubt fat-burning adaptions are very important for races lasting over an hour particularly marathons and ultras. Any runner interested in middle distance or parkrun will benefit from improving their aerobic base but will need to encourage both fuel sources and this is true for the 10K and half-marathon as well.


This is a book filled with information that can help people build a greater understanding of how to approaching training. What I particularly love is the chapter where Stu Mittleman describes the different sensations you will feel as you move up the training intensity scale. When you’re on a slow, low heart-rate jog you can be in tune with the sights and sounds of the world barely breathing; when you’re doing anaerobic intervals your attention will narrow and everything thing will be focused on trying to catch your breath and get to the end of the effort. I believe running by feel is one of the most important skills all runners could learn.

I don’t agree with using heart-rate monitors to train and applying an age-related formula even less so. I agree though with mixing up the week to have slower paced runs dominating the schedule and this fits with the 80:20 rule. The idea of improving the aerobic system by improving mitochondria is important to all distance runners but this doesn’t necessarily mean fat-burning.

The areas of the book I skip are the sections on muscle testing and what to eat. The latter is more down to my own preferences and the area of applied kinesiology is considered a pseudo-science. Linking say knee pain to stressed out adrenal glands affecting the Sartorius muscle seems tenuous to me and doesn’t fit with anything I’ve experienced but then I rarely get injured or ill.

When I read Slow Burn, I found it contained much I already knew but then I’m a voracious reader when I’m interested in a subject. I think for many people there’s much they could learn but they then need to put it into context of what it is for. This is a book about how to run marathons and ultras if you’re not too worried about your time or getting fast quickly. It doesn’t make any claims that it will help you over shorter distances and, if I’m being a little blunt, that’s because I don’t think it will.

MAF Training review – Part 6 When You Need MAF

My previous articles about the MAF Method discourage using the age-related formula for low heartrate training. But in this post I’m taking a more positive angle because there’s a reason people went to Phil Maffetone and he was able to help them. So while, I’m not a fan of the age-related formula, I am a fan of building good endurance which relates to what Maffetone refers to as MAF – Maximum Aerobic Function. While I’m not going to advocate using his formula, I am going to detail and explain the circumstances where a block of endurance training could be useful.

A parkrunner I know is a very capable runner yet, in a decade of running, his progress has been very limited. In fact, he’s barely knocked a minute off his parkrun time. When we first met he’d been running again for perhaps six months. He’d been a talented youngster, quit and now returned to running as he approached forty. It hadn’t taken much training to achieve a twenty minute parkrun yet in all the running since he has barely scraped under nineteen minutes. Despite training five days per week, six at one stage, he really hasn’t made much progress.

His years of running have been blighted by Achilles’ problems. Whenever he starts to train harder with speedwork his Achilles becomes sore and limits his running. He then backs off the pace until long after the Achilles has healed, only to restart the speedwork and go through the same issues. Until recently he was able to run a 19:30 parkrun at full effort but over the last year he’s developed a hamstring injury and is struggling to break twenty minutes. On the tougher local courses, he can’t even break twenty-one minutes!

If he could go to Phil Maffetone, I’m sure MAF would get him back to health and restructure his training to help him improve. I’d still argue against using the age-related MAF formula because he’s over fifty and training at 125 (further five beat reduction for recent injury) isn’t going to produce decent longterm results. Yet, as you’ll see in the next section, he’s clearly not getting the aerobic development Maffetone would encourage and is running around almost every day of the week at heart-rates which are too high.

A typical week’s training when you need MAF

He typically runs five days per week – three midweek, a parkrun on Saturday which is always a faster effort, a Sunday run which is his longest of the week while the Wednesday run tends to be slightly shorter. He gives himself two rest days which, being on Monday and Friday, space the week’s training out nicely. All in it’s not a bad training structure to follow. Here’s the heart-rate graphs from those five days of training.

I’ve put a yellow line to indicate where a heart-rate of 150 occurs and you can see that on every run he is reaching and surpassing it for a decent portion of the time. In fact, at parkrun the heart-rate reaches 170+ and most days he’ll be hitting the 160s at some stage of the running. He’s not just exceeding 150bpm but exceeding it significantly on almost every run.

I consider the overall amount of time spent running each week to be an issue. Totalling about 25 miles per week in 3hr 20mins it’s not enough for a distance runner. Of course everybody leads different lives and has different priorities so I can’t be too critical. Yet at less than an hour the Sunday run isn’t long enough and it should surely be possible to find more time for it. If he was an 800m runner, an hour might be long enough but he isn’t; he describes himself as a 5K / 10K runner. Apart from a couple of ten mile races and a half marathon; 10Ks have been the furthest distance raced in all these years. This overall lack of training volume is part of the problem.

The average pace for the week is 7:45/mile and the Wednesday run is the slowest at 8:11/mile. Given a parkrun time that is just breaking twenty minutes, Jack Daniels’ VDOT tables suggest Easy runs should be somewhere around 8:30/mile pace. So again, alongside the evidence of the high daily heart-rates, we’re getting an indication that there isn’t enough genuinely easy running taking place.

There’s two more problems these stats don’t reveal. On each of the training runs he stops to cross roads which give him one to three minutes recovery on any run. There’s over nine minutes of stops built into these runs. It may seem picky but anyone who has done distance training knows a break is refreshing. If you’re running anaerobically those breaks allow you to recharge the batteries and keep pushing (too) hard. Now you may argue it’s impossible not to stop but, with good timing and route choices it can be avoided. I often go weeks without needing to stop on any of my runs simply by running on roads with low levels of traffic, early in the morning and being flexible about when and where I cross roads. I will happily run an extra fifty paces up a road to let traffic die down before crossing it. But obviously do the safe thing.

The other unseen problem in these graphs is there’s some decent hills on the routes. He’s trying to maintain the same pace up and down them but that pushes the effort up which explain some of the higher heart-rates.

Graphing all those runs differently we can see the time spent in a MAF-HR zone of 130 or less; a middle zone of 131-150 which is usually safe for older runners to train at and a 150+ zone where the training effect is large but also takes time to recover from.

It’s clear he’s running hard five days per week with heart-rates hitting the 150+ mark. You would think the two rest days would be enough but they aren’t. What’s actually happening is the muscles are being trained anaerobically. The days after the rest days (Tuesday and Saturday) are faster runs because the muscles are refreshed but all that allows is for him to go out hard and reinforce the anaerobic training. There is no aerobic development. One of the benefits of day-in, day-out training is it leaves the legs somewhat fatigued to the point where they have to go slower and that helps the aerobic development.

The main consequences of this approach are that he’s getting injured and not improving.

What good training looks like

Injuries were the sort of thing Maffetone was happy to dive in and sort out. As I have stated repeatedly, I’m not a believer in the age-related formula but I am a believer in what Maffetone was trying to get his clients to do which is stay healthy and get faster by building an aerobic base through good endurance training.

My own training during this period saw me run nearly double the training our Needs MAF runner was managing. I was just shy of fifty miles taking 6hr 24mins yet we had the same average pace for the week at 7:45/mile. Despite all this extra mileage I’d been training every day for almost three years without illness or serious injury. While I picked up a couple of glute strains along the way (which came from trying too hard in speedwork) neither lasted more than a week and I was still able to run. While our parkrun times are similar, my base endurance is improving and I am positioning myself to go faster in the longterm.

You can see I run every day but only push harder on two days (Tuesday and Friday). There’s a few little glitches on my heart-rate monitor particularly Wednesday which highlights the problem of accuracy with heart-rate training but otherwise I’m comfortably well below 150HR on my recovery days. My Sunday long run sometimes scrapes into the red but the training effect I’m interested is in building endurance on those runs. Even a good ninety minute run is still only a hard, aerobic effort. Where the Needs MAF runner has to take two rest days every week, I’m getting out there and running on them too.

Another intriguing detail of our training weeks is that we accumulate the same amount of 150+ ‘red zone’ training time but my extra running accumulates time and fitness in the supporting zones while allowing the body to recover from the harder sessions. If I tried to run hard every day like he does, I’m sure I would be getting injured too.

We’re both fifty years old and Maffetone would like us to be doing all our training to a heart-rate of 130 or below. I don’t believe in that but I do total over an hour of my weekly running at this level and it’s usually in the first couple of miles of the runs while my body warms up. This is important – I’m listening to my body to get an indication of how it feels and whether I can push hard. Maffetone talks about doing warm-ups in his book but the people who think he’s only about low heart-rate training miss this.

On days following a harder effort I find my legs don’t want to do too much and it is a struggle to get the heart-rate up. My legs can be glycogen-depleted so I just jog along to aid recovery. If I tried, I could probably push to higher levels especially if I’d had a day off but I don’t try to push it every day and that was Maffetone’s message.

80-20 training

Much of Maffetone’s work occurred in the 80s and 90s when heart-rate monitors were still new. The science of exercise physiology has progressed a lot in recent years. What we now know, due to the work of Stephen Seiler, is that elite athletes tend to split their training into 80% below lactate threshold and 20% above it.

Throughout this post I’ve referenced a HR of 150bpm. Be careful – 150HR is not THE definitive value to use; it’s the data that was available to me. That the Needs MAF runner trains somewhere around this level most days shows it is probably somewhere around his own.

One hundred and fifty is close to where my lactate threshold heart-rate usually lies and I calculate I have a 76-24% split above and below it. That’s within the bounds of 80-20 training. On the other hand, the Needs MAF runner’s training split comes in at 54-46%. It begins to explain why he’s failing to make progress and getting injured when he starts to do even more intense work!

Arguably it may be wrong to use 150HR to split his training but it’s clear he’s training too hard every day because his body is letting him know through injuries and lack of progress. You can also see when he runs 30secs/mile slower on Wednesdays, he has lower heart-rate so it would be easy for him to include more genuinely easy-paced runs. Doing that, as Maffetone outlined is the key to staying healthy and injury-free.

Although I’ve been explaining all this using data you don’t need a heart-rate monitor to know whether your training is going well. Just a bit of common sense and listening to your body will tell you. When it creaks and groans it’s time to back off.


My six posts on MAF training are among the most detailed and honest articles about it on the internet and well worth reading. I’m trying to help runners get past the idea that training to a single number on a heart-rate monitor is the answer to all their problems. Good training involves scheduling the right mix of sessions at the right times. A block of endurance training like Maf suggests is just one part of what you need. My years of training and coaching allow me to know what to do and when to do it to help runners get fitter, faster and healthier. If you too would like me to help you then please contact me with details of your running and how you think I can help you.

MAF, Hof and Cerutty

Percy Cerutty is one of the forgotten coaches of the 20th century. His most notable protégé was Herb Elliott who won the 1,500m gold at the 1960 Rome Olympics and knocked six seconds off the world record for a mile, that’s pretty good to have on your resume. Cerutty’s methods were consider eccentric and bizarre yet I found some commonality between what he coached and the work of Wim Hof and Phil Maffetone. It’s useful to understand their common ground as, while Hof and Maf aren’t specifically coaching runners, the underlying principle is important to all distance runners and building health. Let’s begin by recapping Maf and Hof!

Phil Maffetone

I’ve discussed Maffetone’s work at length previously. While he wasn’t a running coach, his work as a chiropractor helped many long distance athletes improve their times. His main concept is to build the aerobic system so exercise becomes fuelled by burning fat. Athletes do this by training to a heart-rate calculated using their age, muscle-testing for weakness and changing the diet to eat fewer processed foods, grains, dairy products and animal fats while eating more vegetables, fruits, nuts and seeds.

Coming up with a definition of health is an interesting conundrum, because when you when try, it ends up being defined by a negative. The negative being the absence of illness, injury or any other way the body may be malfunctioning. Just saying health is the perfect functioning of the body doesn’t say much.

Maffetone’s method is about eliminating or reducing, to an allowable level, those things which cause ill-health. When many athletes train they often do so with too much intensity which causes the parasympathetic nervous system to rev up, create adrenaline and generally cause the body to become unhealthy due to the waste products caused by anaerobic metabolism. Maf focuses them on improving the aerobic system to delay the anaerobic system from kicking in and lower its overall use.

While he never specifically coached athletes, he helped them get healthy by improving their aerobic base. His best known success is Mark Allen, who went from runner-up in multiple Hawaii Ironman races to being a five-time winner.

Wim Hof

I recently read and wrote about Hof’s book “The Wim Hof Method” and the three core tenets of his system. Improving the aerobic system by taking cold showers, breathing deeply and mentally focusing to achieve goals. Like any good system of improvement, his method starts off with small challenges and gradually increases so you can contend with more.

Hof is not a running coach either and while he has run a marathon barefoot up Mount Everest and swum 200m under sea ice; I consider his most impressive achievement to be the story of how researchers injected him with E-coli virus. In 16,000+ previous trials participants always developed mild flu-like symptoms from the injection – yet Hof didn’t. A subsequent experiment then saw him train twelve people in his method who also remained healthy despite the E-coli injection. The scientists were amazed yet it seemed natural to Hof.

Like Maffetone, Wim Hof explains the benefits of his method as coming from building the aerobic system up. He talks about how an improved aerobic system keeps the body functioning in its naturally alkaline state whereas anaerobic metabolism pushes it into an acidic state. He explains how deep breathing suppresses inflammation and cleans out waste products in the lymphatic system.

While their descriptions of the specifics may differ, the underlying principle is the same of improving the aerobic system to maintain health and create a strong immune system.

Percy Cerutty

So that’s an outline of Phil Maffetone and Wim Hof’s methods and rationales towards keeping your body healthy. Now we look at Percy Cerutty and how through his own experiences he discovered similar principles and put them into action to turn Herb Elliott into the world record holder for the mile and 1,500m as well as remaining undefeated in thirty-six mile races.

Herb Elliot and Percy Cerutty running barefoot strides

In Beyond Winning, Gary M. Walton writes “Born in 1895, Cerutty grew up in a working-class suburb of Melbourne. He was a weak, sickly, and underprivileged child. When he was six years old, he contracted a case of double pneumonia that caused partial paralysis of his left lung. For years, heavy exercise and especially running caused sever discomfort. He suffered from chronic migraine headaches and was usually sick after races. [Cerutty entered mile races, winning ten – one in 4:32] When he quit running in his early twenties, his health continued to slide. By the time he was 43, he had suffered from a nervous and physical breakdown requiring a six-month leave from his job as a telephone technician.”

This is a man who was clearly struggling with his health but during his six-months off, Cerutty decided to challenge his mind and body. It was do-or-die. He rebuilt his confidence by building up to diving off the high tower at St Kilda Baths, took up weightlifting, hiking and swam in the icy Yarra River near his home. He was beginning to develop his back-to-basics, no comfort Stotan philosophy – a mixture of Spartanism and Stoicism.

He created a weekend training camp at Portsea where runners would come to live in bunkhouses, run up sand dunes and eat raw foods. Walton states breakfast was “rolled oats, nuts, dried fruits, bananas, raw cabbage, brown bread and cheese”. But it wasn’t just about physical exercise, in the evenings they would talk and read books of philosophy and poetry, a purification of the mind.

A typical day at the camp:

  • 7am – 5 mile run before breakfast wherever they wanted to go
  • 8am – breakfast (as detailed above)
  • 9am – swimming, surfing or outdoor chores like chopping wooding, painting, carpentry
  • Noon – training and lectures followed by another swim
  • 2pm – lunch – fish and fresh fruit
  • 3pm – siesta
  • 4pm – weight training (a new concept in the 1950s)
  • 5pm – 10 mile run along dirt roads ending at the sea
  • 7pm – tea and general discussion on a variety of topics led by Percy
  • 11pm – lights out

One of the features of the Portsea half-acre training camp was a 60⁰ sand dune rising 80ft which the record to run up was 11 seconds and which Elliott had run up and down forty-two times on a another occasion. There was the Hall Circuit – 1mile 285yds – which Elliot had covered in 5min21 – as well as a ¼ mile Stewart Circuit which ended up a steep hill. Training wasn’t solely around the camp but also took in the local dirt roads, parks and golf course.

While Cerutty trained Elliot and other runners to world records, his aim was not specifically to win titles or run times. It was about getting the absolute maximum out of oneself. His Stotan creed was about removing the crutches and supports that people of the era were beginning to let creep into their lives. When he toured America, Cerutty was appalled at how Americans were flabby, drinking and smoking too much. While this may have been judgemental and critical we should remember he believed in what he preached and went from constant ill health in his younger years to being able to run a sub-3 marathon at age 50 which set the Victoria state record at a time when the world record was 2hr26.

It’s clear there is a similarity between Wim Hof Method and Cerutty’s training camp using nature to harden the mind and body. Swimming in cold water is used by both as a way to strengthen the will; but Cerutty probably never realised, unlike Hof, that it is strengthening the aerobic system as well. Even so, running on sand, up and down dunes would have had Cerutty’s runners breathing deeply just as Hof recommends. The overlap between their methods seems notable.

While there is less immediate commonality between Cerutty and Maffetone, both recommend a careful diet which involves natural foods and avoids processed ones. Cerutty’s diet though tended to be more carbohydrate-based whereas Maffetone’s doesn’t. But Cerutty was training runners like Herb Elliott for middle distance events where carbohydrates are the primary source of energy whereas the Ironman triathlons Mark Allen took part in need fat to be a key fuel source.

What Cerutty was discovering in his training camps was how to build the aerobic system through a combination of daily distance running at a time when these things were rarely understood. The daily regimen of running for half an hour in the morning, another hour in the evening as well as cross-training with sea swims or surfing would certainly have left athletes tired but improving their aerobic system. The overlap with Wim Hof’s Method is clear and Hof’s method has clear overlap with Phil Maffetone.

All distance runners will improve their times and capabilities by building their aerobic capacity and endurance. While the Stotan approach of Percy Cerutty is no longer necessary, it is easily achieved with a committed approach to modern training methods.

Dealing with the heat

Britain finally seems to have found its summer and a heatwave is predicted over the next few days. This doesn’t bode well for any of us who can’t run early morning or in the evenings when it’s cooler.

There’s no doubt heat, or more importantly humidity can affect your running. While a hot day can be unpleasant, it’s the latter that’s the greater issue because it makes it harder to keep cool. High humidity means there’s high levels of water vapour already in the air and this means the sweat / water on your skin has nowhere to go – it can’t evaporate. So it just sits there and stops you from sweating further which is a key mechanism used by the body for cooling. The heart already works harder, as evidenced by a higher heart-rate, to get more blood flowing to the skin to take away the internal heat which occurs through sweating.

If the body temperature rises too much it can be dangerous. The body usually functions at a temperature of 37-38C but add a couple of degrees to that and it begins to impair muscle function. Get to over 40-41C and you’re in danger of heat exhaustion. Heat exhaustion is problematic and if left untreated it can turn into heaststroke which can be deadly.


I think I suffered heat exhaustion once. I was running at the beach, in the middle of summer, and it was a hot sunny day. The day before I’d done the same route – a ten mile run, five miles out, five miles back and even though it had been hot, I had no issues.

On the second day, I felt fine on the outwards stretch and I seem to recall I had a slight wind in my face which helped me feel cool. Then I turned around and it was hot. Any breeze was now on my back, so I got no benefit and I was running with the sun shining on my front. Where I’d run at 8min/mile on the way out, my 6th mile slowed to 8:30 and I was beginning to feel bad. The 7th slowed further to 9:10 and I took a couple of minutes break, standing in the shade shivering behind a beach hut. My heart-rate wouldn’t drop below 115 even though I was just standing there. I resumed at an easy jog, as I still had three miles to cover to get back to the car, but when the 8th mile came in at a shuffling 9:45 I decided it would be best to walk the rest. I had no further effects that afternoon and the following day I felt fine and was back out running okay.

I’m not quite sure what happened. I’m sure I was a little fatigued from doing the ten mile run the day before although longer sessions were quite common at the time. I may not have eaten or drunk enough before setting out. I find in the hot weather, I am constantly drinking fluids and still underhydrated. One other thing may have been an issue, at one stage of the run I sped up to get past the land train that runs along the prom. This pushed my heart-rate up into the 150s and may have set off a chain of events that I would otherwise have avoided had I just been jogging casually. Whatever caused it, I believe I took the right action by cancelling the session and walking back. Fortunately I’ve never encountered it since.


I’ve always been a big believer in drinking to thirst. Most of the day I have a cup of tea to hand but I don’t force it. When I was more endurance trained and sweated less, I found cups of tea would be half finished. At the moment, with the heat I’m drinking lots of tea and I’m still seeing that I’m underhydrated when I go to the toilet. The colour of your urine is a good indicator – when it’s clear you’re hydrated, when it’s golden or even darker you need to drink more. Even though I don’t noticeably sweat during the day, I’m still losing fluid from the body – water particles will be exhaled in your breathing.

The advice used to be to drink lots before a marathon and to keep drinking throughout. But this became a risk with runners drinking over a litre per hour for 3-4 hours. It could lead to a condition called hyponatremia which can almost ‘drown’ the body’s cells and wash the important minerals out of them. The advice now is to drink to thirst.


Of course if you can do your runs in the early morning or late evening, they’re much more enjoyable. Last Sunday, I did my long run at 5:07am and was home well before 7am. It was cool from start to finish and I still had the rest of the day to enjoy the sunshine.

On other days, I’ve been running in the heat of the day but I don’t mind it. Most of the runs have been for recovery purposes which are deliberately kept slow enough that they don’t cause me to break sweat too much. There is a little but it doesn’t get too uncomfortable. I’ve actually found it’s worse when I arrive home and stop moving. The lack of air circulation causes any sweat to start building up.

The couple of workouts I’ve done in the heat I don’t mind. It’s probably because the intervals aren’t that long and you get a rest afterwards. I believe the real danger of running in the heat comes when you try to hold onto a decent pace for a long time.


If we’re lucky enough to have good weather for the rest of the summer months then it’s worth understanding that it takes around two weeks for the body to get used to the heat. There’s always going to be some degradation in performance because of it until that occurs.

Best advice I can give you is to get out and get used to it. Keep yourself hydrated by drinking to thirst and don’t try to force yourself through anything that feels untoward or out of the ordinary.

One legged chair squats

With my speed improving over the past month, I took another read of Pete Magill’s Speedrunner book to see what extra I could learn. One of the things I’ve found with learning is that rereading stuff is helpful. The first time you read something it may seem to go in and be understood. If you then begin to apply what you’ve read and grow, a reread brings a different perspective on the same material.

Among the exercises listed in the book are one-legged squats. These are nothing new to me and last November I started doing exercises as I wanted to be able to do a pistol squat which is a full one-legged squat to the ground and back up. I did exercises for about six weeks which were beneficial but when combined with the faster running I was doing, my left glute got sore and I decided to put them on hold rather than get injured.

Reading Speedrunner as I sat in my garden last Monday, it was one of the rare sunny days we’ve enjoyed this summer. The front half of the book is an explanation of the concepts of maximum velocity, acceleration and sprint mechanics while the second half details exercises that will help to improve these.

A variation to the one-legged squat was also detailed. Begin sitting in a chair (as I happened to be doing at that point) and raise yourself up out of it on only one leg. This allows you to go with a smaller range of motion plus the security of not falling backwards or collapsing on the floor. I gave it a try.

My right leg was just about strong enough to do five reps, it was a struggle but I got them done. The left leg was not so easy. Almost immediately on trying the hamstring muscles in the back of my thigh were crying out in pain with the difficulty. I could do it but it was on the edge of a strain. Fortunately I know my body well enough to know when to keep going and when to back off. I did the five reps and that was it.

In the following days, I continued to do five reps each leg, each day. The left leg still strained at the effort but subjectively I knew the pain was reducing, so the muscle must be getting stronger. Plus the exercise itself is also an improver for balance and coordination. It’s worth noting that for all the technology we have, there is nothing that could tell me I was improving beyond a subjective assessment.

By Saturday, after five days of this, I was feeling strong enough to do ten reps on each leg. The left leg was still a little grumbly about this, the right leg strong but actually not quite as good at balancing when up out of the chair.


On Sunday I went for my long run and with the combination of miles and a decent pace (rather than recovery) it’s the sort of run where any new form can begin to be ingrained. I didn’t particularly notice anything different with the left leg starting to strengthen up but in the last mile or so, I found my right shoulder dropped and began to swing a little easier. They may not seem connect but the arms and legs working in opposite pairings, so the right leg / left arm swing together in time as do the left leg / right arm.

Fixing form issues is quite often a case of looking at the whole body as a system, not simply focusing on the body part you thing is an issue. A good example of this is when you have a runner who heel strikes. The instinct is to get them to run on their toes more but quite often I find it is happening because their hips or glutes aren’t working properly. And I reckon this is what happened to me this past week. I got the left glute-hamstring area stronger, it worked better and consequently that led to the counterbalance from the right shoulder correcting itself.


I’ve continued with the one-legged chair squats this week and they are getting easier and easier. The reps of standing up onto the right leg are now beginning to feel as easy as it does when standing up as normal onto two feet. The left leg is still a tad weak but it will strengthen up. I’ve noticed the right shoulder seems to be dropping into place more often when running and during sprints my form felt great.

One of the surprises is that I need to do this strengthening work. While I do press-ups, corework and dumbbell curls to keep my upper body in shape, I had always considered running was enough for my lower body, particularly in recent months where I’ve been doing hills. Apparently it wasn’t and while it is difficult, if not impossible, to find a set of tests to identify any weakness; it certainly highlights the benefit of doing a range of activities outside of pure running.
