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 – Feb / Mar 2022

To recap: since my last 800m time trial I’ve spent the winter following the traditional offseason regime of an 800m runner. Building the endurance base while slotting in some fast parkruns to try and build leg strength / speed replicating cross-country racing.

After a couple of months my parkrun time began to drop but it was also clear my top-end speed was limited. This was never a problem for me when I was younger because I used to throw myself into every run, play sports with lots of sprints / jumps and do circuit training. But my thighs have lost 3-4 inches over the past few years by focusing on endurance over speed and I lost over a stone during 2021 (188lbs down to 174lbs).


By end of January, I’d improved my speed for a kilometre interval to 3:42 and moved back towards endurance work in preparation for the Bournemouth Bay Half marathon which takes place this Sunday. The plan was as follows:

  • Monday – 30-min recovery run fasted straight out of bed followed by ten minutes of form drills.
  • Tuesday – session to work on half marathon pace (aiming for 6:45-50/mile).
  • Wednesday – 40-min recovery run plus ten minutes of form drills.
  • Thursday – 1hr easy run around Poole Park – mostly flat.
  • Friday – an hour Steady run around the area – 7+ to 9 miles.
  • Saturday – easy parkrun. As I no longer wanted to work on speed, I only planned to do one all-out parkrun about midway through these last eight weeks just to keep it ticking over.
  • Sunday – while in an ideal world I would have lengthened my standard 11.7 mile long run out past the half marathon distance, I made a choice not to. I’m interested to see whether the last mile or so of the half is a debacle or whether the rest of the training sees me through.

Tuesday

I began February with a couple of 10K-paced interval sessions of 6x1K with 200m jog recovery. These were a follow on from the 5x1K with standing recovery I’d done throughout December and January. By using a shorter jogging recovery, I’d begin to improve the aerobic functioning of the muscle fibres.

My notes show the first session was “trying to fit in one session too many over the past five days” and when you compare the second week’s numbers there’s a clear improvement.

I’d like to have repeated this session for a few more weeks but I needed to move onto working at half-marathon pace where the aim was to do much longer intervals at a slower pace (4:12 – 4:15 per km or 6:45 – 50 per mile). The jog recoveries were a quarter of the distance covered.

While the first week was tough and I barely got on pace for the efforts, the following weeks saw a phenomenal improvement as the distance lengthened out and the body adapted. A couple of the sessions were run on windier days 7-15mph and, while the course I use was relatively flat and on a figure of 8 loop – running into the wind was sapping.

The standout sessions were the 4th and 5th weeks where the 3-mile efforts were worth 20-21 minute parkruns (back-to-back); and then the following week on the shorter three 2-mile efforts the pace came in at 6:27, 32, 37 avg. The final week was slightly disappointing as I didn’t get close to matching it but I think my legs were struggling after an amazing Steady run on the previous Friday.

Friday

With the 7½ mile Steady run I’d been doing through January now taking 53-55 minutes, I decided to go back to an old 9-mile route from home along Gravel Hill and through Canford Heath that would be more challenging due to a long uphill on miles seven and eight.

Notes: 18-Feb run round the shorter 7½ mile route due to Storm Eunice with its 30mph winds that day. The run itself was never too bad. No steady run on 4-Mar as fast parkrun the next day.

The last time I ran this route in April 2020, I set a course record of 1hr08+ so the first run at 1hr06 was a significant improvement. To be running 7min/mile pace by the end of the training block is testament to how this run combined with the Tuesday Threshold session has made a significant improvement to my endurance and stamina.

Saturday

The only fast parkrun came in at 20:48 at Upton House. It was an extremely windy day and my legs were still fatigued from the Tuesday session. So it was only a small five second PB but I’m sure at Poole with fresh legs I’d happily be sub-20.

Sunday

The long run has continued to be early on a Sunday morning usually at 6am and always fasted, straight out of bed.

Having set a course PB on 28-January I was stunned by how badly the following week went. My legs were absolutely gone and barely had any pace. I think it was down to the change in training phase but gradually as the weeks went by the speed quickened up on these despite doing a challenging Friday session each week.

I finished off the training block with a 10-mile run last Sunday up on the flat past Bournemouth Uni, through Winton and back through Kinson. At 7:28/mile it was the fastest Sunday long run I’ve ever done and a real confidence booster ahead of the half marathon.

Mileage

The weekly mileages during this period have been 47, 51, 52, 50, 52, 51, 50, 47 miles for a total of 400 miles in two months. This has been by running every day of the week and accumulating 6 – 6½ hours training time each week. More often the weekly structure has seen Tuesday totalling 10-miles, Friday 9-miles and Sunday almost 12-miles for 60% of the weekly mileage.

Half marathon on April 3rd

I was really pleased with this block of training as preparation for the half marathon – I think there’s a high probability of breaking my 1hr31 PB if conditions are good. I’m hoping to break the 1hr30 but the legs have felt fatigued and I left my taper late.

Even so, the whole point of the past six months was to build a bigger endurance base during the winter ready for another round of 800m training and I’ve certainly done that. I think I’m at the fittest I’ve ever been, it’s just a case now of proving this with race times.

With this improved aerobic base, I’m hopeful I can now begin to push the speedwork harder. I’d shied away from running efforts too fast previously as that usually undoes my training, resetting my fast-twitch muscle to anaerobic and precipitating an aerobic rebuild.

I’m not quite sure how I will train in April. I need to give myself at least a week of recovery running after the half marathon and I’d like to see where my parkrun time is at. After that, I’m intending to resume 800m training and while I may use JackD’s sessions as the basis of my training, I’m going to tweak them to try and help improve my top-end speed. Building leg speed is becoming a priority and I may even start doing some hill sprints – I’m just nervous about that because when I did them two years ago, everything went backwards!

Anyway, let’s see how the half marathon goes and leave the future until after that.
