Improving Sprint Technique Part 2

I’m trying to improve my sprinting by videoing myself and then comparing it to the theoretical model of the best sprinters in the world. It’s not rocket science but I’d like to feel like I’m running rocket powered. While there are distinct differences between sprinting and distance running, even distance runners need to be able to sprint for the finish line and there should be some common mechanics which will carry over to make me efficient over any distance.

For example, as detailed in part 1, I noticed my foot was landing too far out in front of me causing me to vault over it. When I brought the foot closer, my runs began to feel like I’d taken the brakes off and my glutes were doing the work.

The best sprinters have cadences well over 250 steps per minute, often approaching 300 yet I struggle to even reach the 220s. Watching the video of my sprinting it all seems lumbering and cumbersome. While a still image can look fairly decent, watching actual footage tells a better story. When my foot lands it seems like I’m stuck to the ground for an age as my body passes over it.

Watching and rewatching footage I began to see my head and shoulders were rising and falling against the background. The next questions was “Why is that happening?”.  And from that I began to see both my knee and ankle were collapsing and I was flat footed with each step which produced the illusion of being stuck to the floor for so long.

Knee bend just after landing (thigh yet to reach vertical)
Ankle bend

Good sprinters try to maintain leg stiffness (of their support leg) with the knee hardly bending. Their ankles don’t flex much either and they stay up on their toes – the heel never touches the ground. Inevitably there is some flexion in the knee and ankle due to the forces being generated as the weight of the runner lands but the more it can be minimised, the better. Likewise the heel will move towards the floor slightly but never makes contact. This flexing allows the Achilles tendon to load up with elastic energy and then release to help propel them forwards.

Usain Bolt – knee and ankle flexion

If you compare the pictures you’ll see both myself and Bolt are at the same stage of the stride; the arms match, the knee coming forward matches and the thigh of the support leg is vertical. But the foot is completely different. My ankle has collapsed and flexed and the heel is barely off the the ground; Bolt’s heel is notably raised and the foot is at right angles to the lower leg.

Initially I thought there was too much knee flexion but I’m no longer so sure. But there’s a definite lack of ankle stiffness which is causing an energy leak and it’s that which I’ve been looking at over the past month or so.

How to improve is of course always the harder question to answer when you locate an issue. Trying to resolve this became a matter of trial and error. I tried to focus on keeping the joints stiffer. I felt I had the requisite strength to keep my legs and ankles stiffer – after all when I skip / jump rope they don’t collapse, it was just the sprint technique wasn’t allowing me to get it right.

When I ran my sprints and strides I made an effort to maintain stiffness in the joints. I think it was a little beneficial but it put new stresses through my joints and for a time the tendons in the rear of my left knee were feeling swollen. It didn’t stop me running, it didn’t hurt training; but the knees were certainly unhappy if I was squatting down to say get something out of a cupboard. I made sure to keep the volume of these sprints lower though as I knew there was a danger of trying to do too much and injuring myself.

Note – while leg stiffness is important you don’t want your leg to be locked out at the knee because that has a high chance of leading to an injury. Failure to flex under high forces can lead to bone jarring into bone.

Similarly trying to stay up on the toes can lead to issues with calf muscles and tendons and there’s a good reason for allowing some ankle flexion. When the ankle flexes (i.e. the toes lift up and move closer to the knee) the Achilles tendon stretches and just like an elastic band it stores energy. When this elastic energy releases it provides some of the propulsion for moving forwards. While sprinters’ ankles flex the heel stays off the ground but a distance runner’s heel will come into contact with the ground momentarily and this needs to be allowed to happen for the storage of elastic energy.

One of the mental models I’ve been using is to think of how skateboarders paw the ground to keep their deck rolling. They time the kickback to add speed as the board begins to slow. It seems to me sprinters are doing the same thing; but where the skateboarders are able to take a foot off the board, paw the ground and then rest the foot back on the deck; sprinters are trying to stay airborne with just their legs extending down to make a short but powerful contact. You could think of the Roadrunner’s legs whirring along at speed..

The other adjustment I made was to try and get my foot down to the ground quicker – what coaches refer to as a hammer action. If I could move the leg down quicker then it would apply force quicker and the foot would go through quicker leaving less time for the joints to flex but still allowing some ankle flex to load the Achilles.

In trying for this quick contact and to stay more airborne, I’ve found my sprinting begin to morph and on occasions I have felt myself springing along as the Achilles does more of the work. There’s still more to do but I think it’s heading in the right direction.

The Hare and the Tortoise

You may recall as a child being told Aesop’s fable about the hare and the tortoise – the story of the speedy hare taking on the slow tortoise in a race. From the start, the hare races off into a lead, certain to win, while the plodding tortoise is left behind. Confident of victory, the hare takes a nap and while he is asleep the tortoise passes him. When the hare awakens he see the tortoise approaching the finish line and, despite his best efforts, the hare is unable to catch him and ends up being beaten. Parents and teachers love to tell this story as a way of saying “don’t rest on your laurels”, “don’t get lazy”, “keep putting in the effort”. The hare doesn’t, the tortoise does.

Now if, like the hare, you’re a runner for whom speed comes naturally – racing 5Ks or 10Ks is never going to be a problem. You might slow a little towards the end but fatigue is rarely enough of an issue that you need to have a lie down and sleep. And as much as the slower runners may plod steadily they’re unlikely to beat the hare.

But step up to a longer distance where fueling plays an important part and it will happen. I got serious about running when I had my own hare/tortoise moment. At the time, I was capable of running a 5:55 mile and 21min 5K parkruns (6:45/mile) and I entered a half marathon. I did some training towards covering the distance in the preceding month or two but it wasn’t extensive. I made the mistake of looking at race calculators which suggested I’d be capable of running around 1hr35 – this didn’t seem out of the question as I’d run 1hr38 the previous year. My running had been sporadic since. Even so I certainly wasn’t that unfit.

Hareing off I ran the first mile in 7:22, the next with the field beginning to spread out in 7:05 followed by 7:31 and 7:20 to take me through four miles in under thirty mins. It was all reasonable so far but miles 5 and 6 came in at 7:45, 7:51. There was a stretch of gradual uphill in there so I wasn’t too concerned. It was after that when the wheels came off.

Mile 7 was 9:00 and mile 8 was 9:38. My legs had gone. My stride was non-existent, I felt terrible. While I didn’t stop for a nap like the hare, I stopped to talk to a couple of running mates. I walked a bit and took 20min30 to cover miles 9 and 10. Then I summoned up the energy to restart and jogged the last three miles averaging 8:40 surrounded by runners who were theoretically much slower than me. I finished in 1hr51. It was a frustrating debacle. If I’d known how bad it would be I could simply have set out at 8:30/mile and got round comfortably.

What it did though was to kickstart me into take running seriously. I spent the next couple of months building a decent aerobic base – a term I didn’t then understand – but which I now teach to runners. Six months later I ran a 1hr31 half marathon.

On that fateful day, I’d finished surrounded by the tortoises who had gone out steadily within their capabilities and knocked off mile by mile. Meanwhile I’d hared off at a pace which was slower than my 5K but without the training to back it up – giving myself no chance of success.

The moral of my running story is twofold:

  • For the hares – if you enter a long distance race make sure you have done the training to back up the pace you’re intending to run. If you haven’t then you need to take it a little easier.
  • For the tortoises – if you can plod along and finish the race comfortably, it’s time to dig out some speed and challenge yourself to leave your comfort zone.

Aerobic Training Takes Time

If I offered you the chance to take two mins off your 5K time in a couple of months – I’m sure you’d jump at the chance.  Of course this depends on how fast your current 5K time is, but it’s exactly what I did when I went from a 5K parkrun time of 25:03 on 1st February to 23:11 on 15th March. Speaking accurately that’s not quite two mins improvement but it’s also much less than two months! And I did it through almost pure aerobic training.

That improvement is going from a pace of 8:03/mile to 7:24/mile – which is about 39secs – an average of 6-7secs/mile per week. Think about that if you did this training for three months you might expect to be running a mile per minute quicker than you were. What’s the catch? Why doesn’t everybody do this?

Anyone who’s read about aerobic training and especially a system like MAF training will know the literature says improvement will be slow. They interpret this to mean it will take months. They interpret it to mean that when 2-3months later they’re still doing the same pace for the same heart-rate, they just need to be a little more patient. That’s a wrong interpretation – if they’re months down the line with no change, then it’s clear indication their training is ineffective.

Here’s what aerobic training takes time really means …

Aerobic training log

On Saturday Feb 1st I ran 8:03/mile. On Sunday I did a 3-mile run at 8:05 pace. On Monday I did a 2-mile run at 7:45/mile. On Tuesday I did a 3-mile run at 8:11 pace. On Wednesday I did a 3-mile run at 7:58/mile. On Thursday it was another 2-mile run at 7:38 pace. On Friday it was a 3-mile run at 8min/mile.

On Saturday I returned to parkrun and ran 24:46. On Sunday I ran three miles at 8:37/mile. On Monday it was a three mile run again at 8:36/mile. On Tuesday it was two miles at 8:24/mile. On Wednesday, three miles at 8:26/mile. On Thursday three miles at 8:17/mile. On Friday it was the two mile run at 8:05/mile.

On Saturday I didn’t go to parkrun but ran from home for three miles at 8:31/mile and then did the same three mile run on the Sunday at 8:08/mile. On Monday it was the two mile run at 7:42/mile. On Tuesday it was three miles at 8:25/mile. On Wednesday the three miles came in at 8:01/mile. On Thursday it was the two mile run at 7:46/mile and on Friday a three mile run which was paced at 8:28/mile.

Are you bored yet? Keep on reading there’s still another three weeks of running data to go through.

On Saturday I returned to parkrun and ran 24:21 which is 40+ seconds than three weeks ago. Improvement is already showing up. Sunday I went out and ran three miles at 8:20/mile pace. On Monday I ran two miles at 7:31/mile. Tuesday was three miles at 8:08/mile. Wednesday’s run was the same three mile run, this time at 7:53/mile. Thursday I was back on the two mile run at 7:31/mile. And on Friday I did three miles at 8:23/mile.

On Saturday I was back at parkrun running 23:52. Another surprise thirty second improvement over the previous week. Sunday’s run was three miles at 8:00/mile. On Monday it was the two mile run at 7:26/mile followed by three miles at 8:15/mile on Tuesday. Wednesday was three miles at 7:53/mile and then on Thursday it was the two mile run at 7:36/mile. Friday was clearly a tired leg day as the three miles were run at 8:58/mile.

The tiredness meant I gave parkrun a miss on the Saturday allied to it being a wet and windy morning. Nonetheless I still did three miles from home at 8:37/mile pace. On Sunday it was another three miles at 8:22/mile. Monday was the two mile run at 7:43/mile. Tuesday, three miles at 8:35/mile with Wednesday’s three miles coming in at 7:56/mile. Thursday I did another two mile run at 7:41/mile and Friday was 7:58 pace on a three mile run.

On Saturday March 15th I went to parkrun.  My legs felt great and I ran 23:11.  Almost two minutes quicker than six weeks before.

If you didn’t bother to read all that in detail, I don’t blame you. I could have produced it in a graph or table to give quick visual understanding but I deliberately wrote it longwindedly to make a point. To read it properly requires great patience. And that’s what runners need if they’re going to get aerobic training to work for them.

The training consists of the same thing day-in, day-out with slight variation in pace. Some days are faster; some days are slower. There is no clear pattern of progression other than at the parkruns. Not every runner has the luxury of a local parkrun to measure their progress.

On top of the basic detail I give you, bear in mind this is just the running. Think about what you do with the other twenty-three hours of your day. Getting up. Breakfasting. Work. Lunch. More work. Evening meal. Watching Youtube or television. Sleeping. My week includes going to the gym on Mondays and Thursdays. That’s why Tuesday and Fridays are always notably slower. If you’ve been promised aerobic training will make you faster then you’re eager to see results and those other activities are taking up time before you can go for your next run.

Living through days after day of just doing simple aerobic runs where the pace might be a little faster or slower than the day before can be tough as it doesn’t bring clear results. It’s not like starting a weekly speed session where you will see quick gains. For example last summer when I was running a 440m lap of my road I went from 6:01/mile to 5:01/mile in three weeks.

There’s a temptation for runners – “I now feel better off the bit of aerobic training I’ve done and just jogging around every day surely won’t help forever; perhaps it’s time to drop in some speedwork as I know it’s worked for me in the past”.

They say “a watched pot never boils” but that’s what runners doing aerobic training often do. They keep checking, comparing their times and paces looking for that improvement. If they use a heart-rate monitor they’ll be including that data.

All this is a great example of where you have trust the process. Set the target of doing a block of aerobic work then just get out and do the runs and don’t worry about the results. In a few weeks’ time you’ll see they’re getting faster.

When coaches mean say “aerobic training takes time” I’ve tried to show you what they mean. You should begin to see some kind of improvement in three weeks whether that’s a faster pace, a lower heart-rate or just feeling better on the runs. It might take six weeks to begin to see notable change but if, by 8-10 weeks everything is still in the same place then your training isn’t effective. It’s time to change direction.

Winter Gym is Over

I needed to get stronger if I was ever to run faster. This was my reason for signing up to the gym. At home I have some weighted vests, dumbbells and other equipment for the workouts I’ve been doing the past few years but I realised if I wanted to get stronger, I needed to lift heavier. That presented a choice – either buy more equipment which would take up space in my house and get used relatively infrequently or join the gym.

Ahead of returning to the gym I began to get excited thinking back to the times I’d lifted weights before. There were two primary periods – at the start of the 1990s when I was a teenager and in 2007-08 in my late thirties. I remember being able to bench press multiple reps at 90kg as a teenager and squat reps of 130kg in the Smith machine in my thirties. Now in my fifties would I still be able to achieve these standards?

While these might have been classed as goals, I wasn’t interested in setting specific goals. I had a vague goal – get stronger and stay healthy. Consequently the first few weeks in the gym were spent very carefully setting up for squats, deadlifts and bench press in the free weights area. Partly making sure I understood how to set up the equipment correctly but also prioritisiting technique over lifting heavy weights. I also didn’t want to get sore by trying to lift anything too heavy, too soon.

In the first session I found myself comfortably half-squatting 8 reps of 50kg and bench pressing 5x60kg. Four weeks later I was doing some half squats at 110kg and struggling to bench a couple of reps at 70kg.

My priorities have changed over the months as I identified weaknesses. For example, with the bench press, I attempted to press 80kg at Christmas and failed. I didn’t make the progress I was hoping to make considering I’d been able to do 65kg on my second session. So I moved to using the Chest Press machine to see if that would help. It didn’t and when I attempted 80kg again in my final session I got stuck and had my spotter give me a little bit of help to get it past the sticking point. Maybe next year.

Similarly I went to the gym intending to strengthen glutes and quads using squats and deadlifts. I stopped deadlifting at Christmas because I had a pulled a muscle in my back and need it to recover.

Injuries like that have been a part of this gym training but not while there. Both sides of my back (rhomboids) and both hamstrings have been strained but these injuries occurred while doing sprints. I believe it’s because I’ve strengthed the muscles and am now putting forces through other parts of the body which aren’t used to it. Injuries led me to add exercises to strengthen the adductors, abductors and hamstrings (leg curl) which can only be beneficial.

With squats my initial aim was to push the weight as high as possible over the training period. I reached 149kg just before Christmas in the Smith machine and added another 10kg just after but unracking the bar began to feel like it was squashing my torso even just standing with the weight on my shoulders. At the same time I realised my deep squats, where I could barely do a single effort at 70-80kg, were too low by comparison and since the New Year I focused on upping this. It’s been very successful as I managed to do a 100kg deep paused squat in my final week and felt there was capacity for another rep. I still occasionally worked the top end and managed to do multiple sets and reps of quarter-squats at 160kg in the free weights area.

On my final leg session I repeated my so-called Seb Squat Challenge which I did with half squats at Christmas and this time attempted it with deep squats. I completed it successfully but it might well have been the toughest session I’ve done. The ten reps at 85kg left me gulping for breath, just like when I’ve been sprinting!

Going to the gym twice per week has been enjoyable without feeling like I’m overdoing it. With my sessions on Mondays and Thursdays, it’s allowed me to go to parkrun on a Saturday with relatively fresh legs. While I didn’t have a benchmark run from before the weights I ran 23mins in my first month, the same again at Christmas, slipped to 25mins while injured and then have rebuilt it to 23mins with increased daily runs of 2-3 miles but no speedwork outside of very short sprints.

And this non-movement in parkrun time is while having putting on about 15lbs / 7kg / 1-stone in weight. My legs have grown by 2 inches / 5cm; as has my chest and arms – I look more like a rugby player than a runner. I detailed how my gym shorts ripped last month and when I put my tailored shorts on again a few weeks back they no longer fitted, they were far too tight. It’s been like that with most of my clothes.

It was never my aim to get bigger but I guess it’s inevitable as you add strength. I deliberately did low rep sets which are meant to avoid muscle hypertrophy. I particularly didn’t want to add upper body weight which doesn’t provide much, if any, benefit to running and maybe that’s why my bench press never improved back to my teenage days. But I was never in this to look good, it was always about functional training – providing muscle for power and health.

There is no doubt it has been an excellent investment of my time. As a general estimate I’ve added 20-30% strength in all the exercises I’ve been doing. I notice when I’m running I feel very stable around my core, my legs feel strong and that there is more to come.

While I could continue going to the gym over the summer, my aim is now to focus on turning the strength into power and rebuilding my lacate threshold to run faster over sprints and parkrun. I’m also interested to see how my body reshapes without any gym work, how much of the strength I’ve developed is retained and how quickly I can reaccess it next winter.

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.

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.

Update on my 800m training – Jan 2023

I feel like I’m in wash-rinse-repeat with my training at the moment. I keep cycling through the right training sessions yet the race results keep coming out the same. I can see some improvement in the stats and speed, yet when I race it is no faster. But this really is the secret to coaching – figuring out where to apply effort.

Coming into January I was working on top-end speed using short intervals lasting around a minute. The pace was intended to be at my calculated 3K-pace broken into sets. The sessions I did were made harder by high winds and I ran my 300s along a section of road which caught the brunt of it along with a gradual hill in the first/last 100 metres depending on which direction I was headed.

Illness strikes …

I had done two sessions at the end of December then my Sunday run went backwards. I wasn’t too concerned as a VO2 lull usually happens at the start of a new training block. But there was a concern – my sister brought a hacking cough to visit over the Christmas period and I fell under its spell. I wasn’t terrible but I was struggling. Yet after a couple of days, I felt slightly better and mistakenly did a 3rd session which, while generally close to target, led me to scale back training as the coughing got worse. I missed the next session of 300s and focused on getting healthy, but was still running each day. By the following Monday it had gone. My mother is still coughing all these weeks later whereas mine was gone in ten days. This is why I believe in keeping fit and healthy especially as you get older. With a good aerobic system your body’s immune system can fight stuff.

Race taper

With only two weeks left to the rescheduled Christchurch Christmas 10K, I knew I needed to taper so I did one more session of 300s and then an even sharper session of 10x100m with 30s standing recovery aiming for 5:30/mile. I found them really easy which probably aligns with why I’m better suited to short distance than long.

A week ahead of the 10K, I went to Poole parkrun on what was an atrocious day. Very high winds and rain. It was absolutely pelting down as I arrived but had eased off by the start. Once again my speed seemed lacking as the first kilometre only came in at 4mins. Along the windiest stretch I ran a 4:20km – at 6’2” and broad I’ve got a large frontal surface area to be blown back. The finishing stretch headed into the wind a second time and having passed them earlier, five men now passed me as my pace dropped to 8min/mile and I felt like I was barely moving. My finish time of 21:02 was good enough to place 19th. I’d guess it’s a long time since Poole parkrun’s 19th finisher ran over twenty-one minutes. While I could make excuses for the wind and rain, the fact is my opening kilometre of 4-mins was fresh-legged and running with the wind; however much others may suggest a sub-20 was on the cards; it wasn’t.

Race

Christchurch 10K itself reinforced this analysis. The run was another cold morning and it was a shame to see the race not as well attended as it would have been before Christmas – less than 200 runners. Many of the others had deferred their places until next December because they’ve started marathon training or other races were taking place on the same day.

I set off quickly not holding back, but again my kilometres were all over four minutes. I reached 5K in 20:38 and then held on for the second half to finish in 42min08. I was somewhat disappointed as it was only fifteen seconds or so faster than last year. All my efforts from a year’s training had added barely anything. However my heart-rate monitor told a different story. Last year my average heart-rate was 159, on this day it was only 152. That’s incredibly low for me on any race. I’d expect it to be up around 161bpm. What it suggests is my fuel source is mostly aerobic but something is blocking me from running faster. When I look at the final miles the pace is consistently 7min/mile.

Finding the problem

On the Tuesday before the race I did a 7-8 mile Steady run averaging 7:17/mile. I felt blocked to run any faster, when I arrived home I realised I had put in more effort than I should have. On the Friday following the race, I did a Steady run at the beach – just letting my body pick up speed and it settled around 7:35-40/mile with heart-rate hitting 150ish. It was a completely comfortable run but slower than I expected.

The day after the Steady run at the beach I went to Upton House parkrun and ran 21:58 averaging only 149bpm. I started slowly and picked up pace as the run went on. But again, it was a big effort to get any much quicker than 7min/mile on tired legs.

A quick look at my old favourite, the Jack Daniels’ tables shows a VDOT of 49 results in a 20:18 5K and 42:04 10K. My Christmas Day parkrun was 20:27 so matches up quite nicely to this. Jack’s tables give a Threshold of 6:55, a Marathon pace of 7:24 and Easy run pace of 8:40. Each of these matches with what I’ve found in training.

Fixing the problem

All these facts – speed of steady runs, not being able to run quicker at parkrun or 10Ks, lower heart-rate when racing, feeling the pace at which I have to put effort in to go faster suggest my aerobic system is clogged and causing the anaerobic system to kick in too early.

In all my years I’ve learned that you have to trust the results from races, especially longer ones where speed counts less. However good things may feel in training or what the heart-rate monitor may suggest, race results are the best guide to what needs to be done.

I could probably just get faster doing Steady runs twice per week with easy runs or recoveries on other days but I want to experiment a little. I want to see whether I can do the same set of Threshold intervals I did this time last year but with more control. I’m going to stay at around 7min/mile as VDOT suggests it’s my Threshold and see if that filters things down.

The block of training I did last year through February and March went well and began with intervals at 6:50 pace and by the end I was closing in on 6:30; but when I arrived at April’s half marathon my legs had nothing. I’d overcooked it. This time I’m going to make sure I don’t exceed Threshold by focusing on my breathing. That will be my guide. Last year, I was pushing efforts to hit a target and it didn’t work.

I did my first session on Tuesday and having warmed up for two easy miles averaging 7:20/mile – not that far off the repeats pace – I began the session.  I accelerated just past 7min/mile and the mile repeats then felt limited at around 6:55 – in line with Jack’s prediction. But, unlike last year, it never felt too taxing and I never had to push harder to hit similar numbers. I’m going to give it three weeks of these and see how things are progressing. If it isn’t going to plan then I’ll drop back to doing the Steady runs instead.

Update on my 800m training – Dec 2022

I reached December after three months of training to boost lactate threshold and began tapering for Christchurch 10K on Dec 11th. My performance at Boscombe 10K on Nov 27th was less than desirable but I knew I was still early in my taper. As I reported in November’s update, I ran easy all the following week and my legs began to freshen up nicely. It was quite a change to be simply going out and not doing any thing extra where usually there’s some kind of workout or longer steady effort each week. Each run was limited to forty mins and in the week before raceday I began to reduce this further. On the preceding Tuesday I found myself running five miles in under 36mins which is better than my last five mile race in 2019!

Anyone living in the UK this month knows how bitterly cold it got. Reading the forecast I had doubts whether the race would be on and come raceday I drove there with the car’s external temperature gauge reading -3C while slushy rain, or maybe it was snow, hit the windscreen. Walking to get my number presented a hazard in itself with the pavements very icy. I sat in my car shivering despite being wrapped up and, in a rare display of negativity, hoped the race would be called off. It was. Ice is my one major concern when it comes to running and I felt sure with the temperature still around freezing that it wouldn’t get warm enough to melt any on the course. The organisers came to the same decision.

I went for a run later in the day, taking it carefully around local roads then next day went to the beach to do some interval work. I figured the one place that wouldn’t be icy was somewhere with lots of salt water and sand!

That same day I received an email from the organisers saying they were hoping to reorganise the race in early 2023. While this was great news it also left me in limbo not knowing when it might be or how to train so I just continued with the easy / steady runs. On the following Saturday with the intervals out of my legs, my early morning run just flew. My forty-one minute run covered 5.8 miles and I barely got out of breath. The last mile and a half was on the roads by my house and I was hitting 6:35/mile. It felt great.

A week later, with Christmas Day falling on Sunday, my usual long run day, I ran down to Poole parkrun. My legs felt good but seemed to lack another gear. When the parkrun began my glutes fired in a way I’ve never known and I was propelled forward yet I didn’t seem to have the pace to break twenty minutes. I managed to put in some surges to overtake runners but could never up the pace for long and finished in 20:25. Slightly disappointing from the perspective of being fifteen seconds slower than last year yet a feeling that the run was a breakthrough as I’d jetted along. The run home felt comfortable and I found myself able to run closer to seven minute miles as I approached home despite having already put in 10+ miles.  When I analysed my parkrun I found that while the kilometre splits reflected the small up and down gradients in the park, my mile splits came in at 6:31, 6:32, 6:33. A consistency suggesting I’d hit my lactate threshold but had nothing more to give. It identified the direction I now need to take training.

Looking back it’s almost six months since I did any dedicated speedwork. At the beginning of July I was passing my peak and finding my aerobic endurance starting to decline. All my training since then has been focused on rebuilding stamina and raising threshold. It seems I’ve been very successful at this but my fast-twitch have been deactivated in the process. This is very much expected and part of the periodisation process Arthur Lydiard coached his runners with back in the sixties.

The aim now is to start doing faster efforts lasting around a minute to rebuild anaerobic capacity and give me the speed to push harder at parkrun next time.  The session I’ve picked is three sets of 4x300m with 45secs rest and three minutes between sets. I’ve done two sessions of this workout and the results have been good. I’m aiming for around 66-67secs per effort and on the first session, only two days after parkrun, I averaged 66½. The course I’ve picked is straight but does have an up / down nature to it and it’s been windy this past week. I’m finding the downs are closer to 61-62 whereas the ups are barely hitting target. The second time I did the workout my legs were fresher and I averaged under 65s and was able to hold back on the privileged efforts.

The news has come through that Christchurch 10K has been rescheduled for Jan 22nd so that’s what I’m now working towards with these. I think I should manage two more full weeks of them and then take it easier in the week preceding the race. After that I’ll look to go back to winter endurance training and prepare for an April half marathon. I’d also like to get to parkrun and run a quick one at some stage.

Update on my 800m training – Nov 2022

Winter training continues with building the aerobic base. In October’s recap I detailed the nine weeks of solid aerobic and threshold work I’d done since late August. Now my thoughts turned to faster anaerobic training at 5K and 10K paces in preparation for two 10K races.

Each week I ran kilometre repeats twice. On Tuesday’s it was 5x1K with 3-min standing recovery aiming for 3:48; Thursday was 6x1K with 200m jog recovery aiming for 4:00. I returned to an undulating course which runs alongside a main road. In one direction it is net downhill which are the 1st/3rd/5th efforts while the uphill occurs on the way back. Despite November being full of high winds and rain, I couldn’t have had more perfect weather when I ran. Somehow every session was still, blue skies and sunny.

The sessions came in as follows:

Alongside this I started doing some body weight squat work on Tuesdays and Fridays to try and strengthen up my quads and glutes. When I tried these last year I discovered my left glute was particularly weak; this time it was strong from the first session and I decided to build up my volume slowly. I even started doing a couple of minute’s worth of balance work on each foot to try and improve balance as well as taxing the kinetic chain up the leg.

The net result of all this was, as you can see from the sessions, my legs couldn’t cope with what I was doing and I started going backwards. “No matter” I thought as I’d deliberately planned a three week taper into Christchurch 10K on December 11th.

The taper started on Sunday 20th November when I ran a shorter (10-mile) long run on a flatter course than usual. It was the best time I’ve ever recorded on the route – under 1hr14 on a fasted run straight out of bed. It was a real confidence builder but in retrospect perhaps it was too much only a week out from my first 10K at Boscombe.

The first week’s taper included the final 5K session which, coming two days after the best ever long run, was a little disappointing. But I still had five days for the legs to recover before running the 10K on the Sunday. It turned out to a somewhat disappointing race as I clocked 42:49. I thought my legs were beginning to perk up when I ran in warm-up (I was amazed to see myself running 8:20 pace at 122 heart-rate) but the first kilometre of the race was only 4:07 and I never cracked four minutes. When I compare that to my training intervals I’d expected to have some sub-4s and be holding back in the beginning.

The question is why did I not run well? The conclusion I came to is my legs were carrying too much fatigue and muscle damage. Now that isn’t necessarily a problem as the whole point of tapering is to let the legs freshen up. The first kilometre of the race not being able to get close to what I’ve done in training really highlights the legs were under recovered.

Looking back over the past few years of running this has been something of a perpetual theme. Trying to run races or parkruns without a decent taper. Or to put it the other way round, doing too much training during the week which I’ve been unable to recover from. I’m always a lot more careful with runners I coach but my legs more often than not haven’t felt painful or tired by the time a race comes around so it hasn’t seemed like that’s the reason I’ve underperformed.

I think the biggest culprit has been pushing the Sunday long runs along rather than allowing the pace to come to me. It becomes a third workout for the week. When I was racing well a few years back; I never pushed the long runs just did them easy. Yet I’ve been arriving home and not feeling tired or hungry which suggested I hadn’t overdone things. I’m not some of the weekday sessions haven’t been too big either – I’ve been chalking up fifty miles per week and following the 80-20 rule and that’s where the limitations of using heart-rate monitors and formulaic training appears – there is no easy way to identify how much muscular damage you’re suffering other than by results.

Three years ago I started a run streak that lasted until April this year when I finally took six days off around the Bournemouth Bay half marathon. That’s another race that didn’t go well because my legs were heavy and fatigued. That was why I decided I needed a three week taper for Christchurch 10K.

But I also didn’t recover enough after the half marathon. The rule of thumb is to recover for a day per mile of racing yet a week later I was beginning my next block of training and doing hills for the first time in a couple of years, so I accrued more damage on other damage. It’s hard to look back and know when I last had a block of training where I wasn’t on fatigued legs. Maybe it was late October 2021 after an 800m time trial or the May before that. Whenever it was, it was a long time ago. If I go back to 2020 I did some very easy running when I started all of my 800m training.

As I said before, the point of tapering is to give the legs time to freshen up. Since last Sunday’s race, I’ve gone out and run easy for forty minutes each day. Genuinely easy or effortless runs as I like to call them. It’s felt lovely to arrive home from every run and feel like I could go round again. The avg. pace has gradually improved over the week – Monday 8:24, Tuesday 8:11, Wednesday 8:03, Thursday 7:47, Friday 7:31, Saturday 7:27. None of this has been forced, it’s just what happens as the legs freshen up. Yet I can still feel a little bit of missing oomph and spring from my legs, there’s still more damage to repair.

With the improvement I’ve seen over this past week the temptation is to believe the legs are ready to run and squeeze in one last training session. That’s the mistake I’ve been making in the past. My legs function best when I let the fast-twitch freshen up. I’d really wanted to go to parkrun and see where I’m at but I only get one shot at my 10K; whereas I can go to parkrun on any other week after the race so I’m just going to keep taking it easy next week and see how it goes at Christchurch. If nothing else I’ll learn a little more about the effects of my taper and how I can best peak for a race.
