Update on my 800m training – Oct 2022

Offseason training continues. I’ve just put in nine weeks of solid aerobic and threshold work and it went both well and badly. The aim had been to improve my threshold from where I estimated it currently to be at 6:50 to 6:30 – so the plan was to do three weeks at 6:50/mile, three at 6:40, three at 6:30.  Each three week block would be a progression of 6×1 mile, 4×1½ mile, 3×2 miles with a jog recovery.

The results came in as follows:

While there were ups and downs in there, I rated the first 8 weeks as having gone decently and there was an overall improvement from where I began to where I’d reached. Not perfect but a definite improvement. You can see the average pace improving over the weeks in line with what I was hoping to achieve.

Then came week 9, it was atrocious – overall worse than week 1. There was a good reason for this. It didn’t simply come down to having screwed things up, I caught something and spent the week blowing my nose hundreds of times each day and waking up through the night. Whatever it was, it raised its head on the previous Friday where I was inexplicably thirty seconds per mile slower than the previous week over my nine mile course.

It lasted for 4-5 days and knocked my fitness backwards. I’m hoping this loss is temporary as the body recovers and returns all its hormones and red/white blood cell counts back to normal. I seem to be okay now.

I’ve written a lot about Maffetone training and while I don’t rate low heart-rate training as a method, I agree with the idea of a strong aerobic system being important to health. It was certainly the case for me. While my running went backwards for a few days, I never stopped being able to do the things I need to do on a daily basis. Once I realised I was under the weather, I cancelled my supplemental training (core work, press-ups etc.) and avoided other unnecessary activities. Basically I took it as easy as possible while still running every day. It’s debateable whether it was worth doing that 9th workout? I wanted to give it a go and just decided to get the best out of it I could. I didn’t push to hit target once I saw how far off the pace I was.


The days of the training week have been building endurance to support this work. I’ve done an hour Steady run on Fridays and an 11.7 mile long run on Sundays straight out of bed. On week 4, I went to Sandhurst Memorial parkrun, where I ran a tired legged 20:48 in place of the Friday Steady run. The parkrun still came in around 6:40/mile which suggests my threshold is improving. Then my Sunday long run* was 12 miles up and down the Basingstoke canal towpath. The legs were naturally not up for a faster effort after an all-out parkrun.

What’s strange is my Fridays haven’t been quite as good as they were six months ago when I was doing a similar block of training yet the Sundays have been really pleasing. Almost every week has been a sub-8 avg. pace which is a level of consistency I’ve never seen before. It hints that I’m finally building the base endurance to a point where the body is recovering quicker.


All in all, it’s been a decent block of training through September and October and I achieved what I set out to do. I feel confident I can crack 40-mins in the 10K for the first time since 2015 and then later run a parkrun PB. I’ve got four weeks to the Boscombe 10K and then a further fortnight until Christchurch 10K which is the more likely course to break forty on. These first four weeks are going to see me running kilometres intervals with shorter rests to boost lactate tolerance and clearance and fire up the fast-twitch muscles enough to get me on pace. It’s time to go anaerobic!

Update on my 800m training – Aug / Sep 2022

In my last update I detailed that I had gone back to endurance training as all the hills and speedwork of the spring had toppled my aerobic base. It was somewhat disappointing but also necessary if I’m to sort out my 800m. I now realise I’m done for this year and it’s going to be a winter of building endurance and stamina. The introduction of hills and sprints was great fun but also introduced way too much naturally anaerobic fast-twitch muscle. As I haven’t been near these areas in years, things toppled quickly. Hopefully by next winter, my base will be bigger and I’ll be able to handle the anaerobic side better.

Having restarted endurance training in early July I found I wasn’t making much progress; then in early August I realised I was beginning to get aches and pains of the sort when you’re training too anaerobically. I had to reset AGAIN. My focus became to ensure I set off on runs at a slower pace and built up to my aerobic limits. That reset did the trick as the pains dissipated and the endurance began to build. Even so I was still a good 30+ secs/mile down on where I was back in March. It was a surprise to me how easy it is undo everything.

Mid-August I did an all-out parkrun at Poole and clocked 20:25. Quicker than running there at Easter (20:40) but slower than last Christmas (20:11). I cannot tell you how frustrated I am feeling at not being able to get back under twenty minutes. Another parkrun at Sandhurst Memorial parkrun in late September was even worse at 20:48 but it’s a tougher course and my legs were fatigued so that didn’t concern me.


I’ve entered a couple of 10Ks – Boscombe on Nov 27 and Christchurch two weeks later. I’ve gone back to using the training system I used on my only ever sub-40 run back in 2015. Controlled threshold work on a Tuesday, a Steady run on Fridays and a long run on Sunday. This is the same as I was doing in February and March this year.

My plan is to do intervals at Threshold pace (6:50/mile) for three weeks, then up the pace to 6:40 for three weeks and again to 6:30 which will take me through to the end of October. After that I’m going to do shorter intervals at 5K and 10K pace which will hopefully see me breaking forty minutes again. It’s an aggressive schedule but so far the body has been holding up.


Endurance-wise it took me until mid-September to get back to where I was in February. That said, my fasted Sunday morning long runs have all been coming in at a decent pace, usually sub-8 average for 12-miles, no stops. For whatever reason, I seem to be running these quicker than in February.

Possibly some of the drop off I’ve been experiencing is down to a change in running form. Since last October I’ve been working on my form using drills at least once per week and somewhere around late June, combined with the sprints I was doing, I began to feel I was running differently. Less hip rotation and more power from the glutes. Of course, using muscles that have never been involved in my running, meant they needed to be trained and quite possibly they had a lower lactate threshold due to this. Whatever it is, the form change is beginning to feel powerful at times and I just have to keep working at it.


Behind the scenes I’ve been wondering about whether I’m cut out for training like this. For all the miles and effort, I’ve put in over the years; my improvements have been sporadic. I’ve decided this winter will be the acid test. Hopefully when spring arrives next April, I will see a decent improvement in my half marathon time.  If I don’t then I’m scrapping the endurance focus and putting my training time into working on speed and to see whether I can get my 200/400 times down, even if it’s at the expense of longer distances.

I’m going to give it a fair crack of the whip and train the best way I know how to. The one sticking point is I entered the London Marathon ballot yesterday not realising the race is in six months’ time (April). If this were to be the year I get a place then my training would have to look at lengthening my long run out to twenty miles. Even so I’d expect the training I’ve got planned, to fit in well with how I would need to train. We’ll see when the ballot results are announced at the end of October. I’m currently doing just shy of fifty miles per week and have been for the past two years so the base is there for whichever direction I need to go.

Update on my 800m training – July 2022

The intention entering July had been to get the final six weeks of 800m training done, using JackD’s schedule as a basis, then run a 800m time trial. It didn’t work out like that.

I did the first week and was a bit sluggish on a 3-mile tempo – aiming for 6:40/mile, I ended up averaging 6:54. Not great given I was running 6:48/mile average on similar session in mid-June but I had done sprints two days before so figured that might have left some fatigue in the legs. Two days on, I did 3x600m and only ran 2:05, 2:05, 2:12 where I’d been hitting as fast as 1:58 in training last year and was expecting to go faster – closer to 1:50.

The following Tuesday I did some 200s that came in around 5:20/mile whereas I’d been hitting as quick as 4:50 in April and then immediately went into a couple of individual miles. It was one of the hottest days of the year but I didn’t feel bothered by it. The first mile came in at 7:02 then a 2-minute standing recovery and my legs were like lead and I could only hit 7:28 in the second mile. I’d overcooked it. Peaked too soon this summer.


So that’s it, since mid-July I’ve gone back to recovery work and hour-long tempo runs to rebuild my endurance.  The first run I did I covered 7½ miles at 7:46/mile pace. The fastest individual mile was 7:18 even though that was predominantly downhill.  This really highlighted how much aerobic fitness I’ve lost. At the end of March, just before my half marathon, I was running 9 miles at 7min/mile, now I couldn’t even run one mile at that pace.

This has been the focus for the rest of July and will be through August – rebuild endurance. By month end, I’d reached the stage where I could average 7:25/mile and my legs were begin to run better but I’m still finding it a struggle to run faster aerobically.

But the focus of the last few months has been to recruit more running muscle and build my speed, I think I achieved and now I have to train some of that muscle to be more enduring. It’s somewhat frustrating to see myself go backwards like this but it’s what all elites go through. It’s difficult to build and maintain a peak for any longer than twelve weeks, I’d say I got 8-10 weeks.


The other thing I’ve been working on is strengthening with various exercises, including one legged chair squats, and my glutes seem to be firing and my core stabilising better during runs. I feel like I’m gliding over the ground more than I used to. In the short term this may also be a source of my problems – using muscles that have never been used before and needing to train them more aerobically. Hopefully as the body adapts to their introduction I will speed back up. Whatever it is, I’ve learned that the only way through this is to up the aerobic work.

Update on my 800m training – June 2022

Last update I mentioned improving top-end speed is the priority this summer even if it comes at the expense of other parts of training. I’ve been doing weekly sprint sessions which alternate between hills and on the flat. The general process has been one of starting with a small amount of sprint work and gradually increasing it. Back in April my first session was 6x8secs – a total of 48 seconds effort. The next week it went to 8x8s (64s), then 10x8s (80s) followed. This morphed into some 60m flat sprints which came in at just under 9-10secs each but only four of them to avoid overloading the body with the new type of effort.

The hills then lengthened to 10secs (x8 reps) that still totalled the same 1min20s of volume before pushing up again to 10x10secs (1min40s). On the alternate weeks, 80m flat sprints were taking around 12s and then a 100m in 15s. Back on the hills, a single 20s effort replaced the final two efforts of the previous 10x10sec and oh my, that was hilariously tough. I was good for the first 15secs but as I entered the new territory of the final 2-3 seconds, my legs became jelly and could barely propel myself. That set the stage for adding a 150m sprint (22+ secs) on the flats and then hills went all-in with 2x25sec. This was my biggest session to date at 2min10 of hills and they won’t get bigger. On the flat, the volume is topping out at 700-800m which fits nicely with trying to be 800m runner.

The latest session was 2x60m, 2x80m, 1x100m, 1x150m, 1x200m as it begins to tip towards speed endurance. The shorter efforts now barely tax me but the 150 and 200 were tough. Ideally I would have taken longer recovery times. A sprinter would usually be taking fifteen minutes recovery before attempting the 200m, I took six minutes. Woefully inadequate and I began to pay for it at the 80m mark as the legs tied up and co-ordination went. My hopes of a first recorded sub-30 sec were dashed.

The setting for these efforts are my local roads. There’s a couple of hills nearby, in fact it’s hard to find a decent straight flat stretch off the main roads. There is one round the corner from where I live which has a slight gradient in the middle so I’ve used that. Unfortunately because it gets busier later in the morning, I’ve been out at 7am doing the sprints which isn’t the best time to go with all-out efforts. With it being mid-June and the longest days, I was up at 5am for breakfast a couple of times to get something in before my sessions. I should add I followed the sprints with some other fast threshold-paced type running.

The results from the speedwork seem to be bleeding through and I certainly feel I’m getting more push in the first steps and technique is improving. While the GPS isn’t accurate on the shorter efforts – it takes around 15-16s to get down to the faster paces – it has recorded me running at 3:35-3:40/mile on a couple of occasions which is scarily only as fast as the world record pace for the mile! But go back a year and I was struggling to run much quicker than 4:45/mile pace, so there is improvement.

The only downside of these sprint sessions is they take 3-5 days to recover from. Quite often my Wednesday sessions were a letdown and off target pace; eventually I ditched the Friday interval session in favour of a Steady run.


Nominally I’m following JackD’s plan and I finished off the 3rd phase of training with one of my favourite sessions … 600m effort in 2:03, 30s standing recovery, 200m in 37secs … three times over with a 7-min jog recovery in between.

When I did this session six weeks ago near the end of May my legs were simply too tired and I couldn’t get below 2:10 / 39s for the 600 / 200 split, I totalled 8min39 for the 2,400m.

This time around my times were 2:02 / 39 … 2:05 / 37 … 2:07 / 36 – 8:06 total time. Unfortunately the scheduled day saw me running into a hefty headwind for over half of the 600m efforts. I think they would have been on target on a calmer day, but it did give me an advantage on the 200s although I think I’d have been hitting those numbers anyway.


All in all, it’s been a good month with fitness improving and the goal of improving speed beginning to take place. I can’t believe I’m already down to the last six weeks of training before I attempt another 800m. It’ll be almost a year since the last one by the time I get around to it. I’m not expecting miracles but I am looking for a decent improvement over last year’s 2:49.

Update on my 800m training – May 2022

Was it the hills?  I entered the month feeling positive after some very quick short intervals in April but throughout May my legs have struggled. I started doing hills in April to build speed and they’re certainly feeling stronger but they also tend to take a few days to fully recover.

I’ve never been a decent sprinter but I think I probably should have been. Firstly because I find it easy to put on muscle, and secondly because I’ve never found it easy to be good at distance running. Once I got on Strava I began to see how often quicker runners are able to get better results despite training half as hard as I do. I seem to lack the natural aerobic capacity that many distance runners have.

This is all behind the reason why I decided to give 800m running a try. It’s an event that still needs decent sprint speed backing it up. But when I started following a plan by Jack Daniels eighteen months ago, it didn’t do much for speed recruitment and I made a deliberate decision not to overdo things as I found it easy to run quicker than expected. This again is another reason why I think I’m better suited to short distance racing.

Even so I felt my top-end speed was missing as I could barely get my peak speed below five minute mile. Last February, I started looking at how to improve cadence in the hope this would improve my form for sprinting and top end speed. Six months ago I started doing ten minutes of sprint drills twice per week to clean up my technique. It’s made a huge difference.


So here I am doing Summer Training to build speed and peak for my next 800m attempt. With my aerobic base enabling me to run seven minute miles for an hour in the winter, I decided it was time to introduce hill and flat sprints on a Monday to recruit more running muscle and get faster at the top end. It seems to be working.

Six years ago, I was doing the same set of workouts and my times then for 60m, 80m and 100m approx. were 10½ secs, 12 secs, 16½ secs. Admittedly I tended to do these after another session but this year I’ve recorded times of 8.75s (60m), 11.5s (80m), 14.6s (100m). A definite improvement and fairly good considering I’ve barely done anything like this in the past half-decade and I’m now in my fifties.

I also found on the most recent block of flat sprints I was hitting some high cadences with the two highest values coming in at 262 and 278 on different efforts. I’m slightly wary of whether the cadence monitor is wholly accurate but if it is these are genuine sprint numbers. Again this backs up the belief my form is improving.

The rest of May’s training was something of a slog to hit target paces. Quite often I missed my faster targets but the legs always seemed sluggish after the sprints. This resulted in a decision – I’ve decided though that working on speed over this summer is the priority so if other sessions are a little behind because of that, so be it. Overall my numbers are still an improvement over where they were a year ago.

On into June. This is the hardest block of training. I’ve felt tight and slow on recovery days but hopefully I’ll get through it!

Update on my 800m training – Apr 2022

April has been a month of weeks! Following on from Bournemouth Bay 1/2M on the 3rd, I took a few days break. That was the first week. Then I started training and it was a heavy-legged slog culminating with a not-too-great parkrun. That was the second week. It was followed by three workouts in a week and the legs finally beginning to lighten up. That was the third week. And finally, last week I’ve begun to feel back to where I was in March aerobically.

I’ve been wondering how to approach this block of training. While I liked the structure of JackD’s 800m training plan which I followed for two cycles last year, I didn’t feel I improved enough off of it. Having worked on my endurance all winter, I felt I would be safe to begin working on speed and wanted to use some of the concepts which Steve Magness talks about in his book – The Science of Running.  Most notably this would involve hills and breaking the interval work into sets of 800m.

Hills

Mondays has become hill sprint day. These are the tool espoused by Magness for improving speed and recruiting more muscle. It’s all about short, all-out efforts lasting only 8-10 seconds followed by long recoveries. By working as hard as possible on each effort, you maximise the speed and recruitment without having the legs tie up with fatigue. The long recoveries then allow the energy systems to recharge for the next effort.

My legs have lost a lot of muscle and size over the past ten years. When I was in my early twenties, the gym report states my quads were around 26”; these days they’re 23” at most. It’s no surprise my legs were so strong because every sport I played I went at full-force. Playing squash was lunging two or three steps in each direction. Running round a football pitch or basketball court was accelerations of 5-10 metres to close down an opponent. Playing volleyball gave my legs a good workout with constant jumping at the net or squatting down in the back court. When I went for a run, I started off at a sprint and held on to puff my way round. All of that is the antithesis to how I’ve been training for the past five years.

I followed Magness’ plan back in early 2016 but they were usually done on tired legs, after an hour effort run along the beach promenade. My training progressed during those months but I was doing other good effort sessions at the same time so I can’t quantify how effective they were.

I’ve certainly felt good on this year’s efforts and they have combined well with improved running form from the sprint drills I’ve done since October. The following day is always a little slow but that’s to be expected with the muscle fibres recovering.

Short intervals

My intention was to do my own version of speedwork on Wednesday and Fridays. For the first two weeks I decided to follow Jack’s plan of 200s and 400s until I was ready to implement my own ideas.

The reality is when I started doing these sessions, I found my pace was off-the-charts compared to last year. Having not run a recent 800 time trial, I had nothing to base my training on so I estimated, based on my half marathon training, that I was likely in around 2:36 form and therefore should be running efforts at 43secs per 200m. The first session of 200s all came in at 39-41secs despite having tired legs. The following week I was aiming for 1:26 for 400s and found myself running a couple at 1:17 and a couple at 1:22. This was a huge improvement over the same session in training last year when I was hanging on for 1:30-32. The previous cycle it was 1:35-36 hanging on.

Last year I would feel tired after sessions; this time I’ve been running far quicker than expected but not feeling torn down afterwards. Given I was so far ahead of my intended pace I’ve decided too stick with Jack’s plan and not change anything around in terms of the efforts and splitting it into sets. The only change I have made is not to adhere so stringently to the warm-up and cooldown durations.

The final session of April was two sets of 6x200m with 10-min jog recovery between. The first effort of the second set came in at 35.2 secs which is the fastest I’ve done. Compare this to the 48-secs I was running when I began 800m training in December 2020. It wasn’t just one fast effort, all but one effort was sub-40 and the average came in at 38.16sec.

Near disaster

Despite my success, I’m slightly concerned I may be overdoing these. At parkrun after the successful 200s session, my left Achilles ached and then popped on the Sunday long run. My first thought was “oh no” but I could run without pain and have just seen it as a warning sign. I’ve probably been doing these efforts closer to 800m pace than the intended mile pace and during May, I’m going to focus on pacing these at around 41½ sec per 200 (5:30 per mile).

Actual disaster (minor)

On arriving at Poole parkrun in mid-April, I cinched on my watch and the strap broke. I had to carry it all the way round. That evening I went away to a birthday party and danced until midnight. Next morning, waking early at 5:40am in a strange bed I went for my long run up the Basingstoke Canal. I intended to do my standard 10-12 mile run lasting 1hr20-40 and popped the watch in my back pocket. I didn’t mind running without the numbers but I had no indication of how fast or how far I was going. My legs were so tired from the all-out parkrun and a night of dancing that it was a trudge. The final miles back I gutted through, working mentally hard to avoid the urge to stop and walk. When I arrived back and pulled the watch out of my short’s back pocket, I was stunned to see I’d run for 2hr05 and 14+ miles. No wonder it was tough – that’s my longest run in time and duration in almost two years.

Can’t decide whether to change both parts of the strap!

I carried my watch around in my hand for the next two weeks. It’s impossible to know when to start or stop efforts in an interval session if you’re carrying it in your back pocket. What I noticed is the outsides of my shoulder aching towards the end of runs. I’m not sure if it’s down to carrying the (very light) watch with arms/hands locked in position or whether it’s just the effort of the sessions. I have had shoulder aches at other times when I’ve run fast. Nonetheless it got me wondering about those people who carry bottles which are much heavier.


It’s been a great month of running. I’m not sure whether it’s the hills or the winter training but something has improved about my running since the last cycle. I’m sure it’s down to improving my aerobic system over the winter and closing the gap between the fast paces and my general runs. Where last year the gap was the better part of 3-mins (9-min mile vs 6-min mile) now it’s closer to 2-mins (7:30 to 5:30).

I’m certainly finding it easier to recover between intervals and be ready for the next effort. But I also wonder if that’s partly because they’re being run quicker! Running an effort in 1:17 compared to 1:30 a year ago may not seem much but it’s 15% less time. Friday’s intervals, for example totalled around seven and a half minutes, a minute less than last June and ninety-seconds less than six months before that. While the individual efforts may be using as much concentration and energy, overall there’s less to recover from. This is why elite runners end up doing bigger workouts, they can do more as they get fitter. I could theoretically add a couple of more efforts to be doing the same volume of work as last year.

I’m looking forward to May’s training. My focus is on getting the pace right and ensuring I get enough recovery to avoid any injury.

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.

 Effort 12 (uphill)34 (uphill)54 (uphill)

8-Feb3:584:043:584:104:044:10
6x1K with 200m jog recovery intervals

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.

Update on my 800m training – January 2022

January has been a revealing month for training. It has really ebbed and flowed, showing the typical pattern of ups and downs that every runner can expect. While the intricate details of my training may not be of interest to everybody, the pattern should be.

In mid-December, I concluded I was struggling for aerobic speed. While my top-end speed hasn’t been fantastic I have been able to run 200s at 5min/mile pace but, at all the parkruns I ran through Oct-Nov-Dec, I’d struggled to run any kilometre quicker than 3:55. Compare this to my past and I could run one in 3:45 in 2019 and much faster in the years before that.

I embarked on running kilometre intervals with three minutes standing recovery which had always been an old session favourite. The route I use is undulating with definite up and downhill legs. The recent sessions were slightly complicated by workmen creating a cycle path on the other side of the road and parking their vehicles along the verge. But only on one occasion did this impact me.

I began these efforts on Dec 23rd and did them once per week. The first three weeks showed little to no change but during this time I struggled with my general running. This probably wasn’t helped by running a Christmas Day parkrun (20:11) between the first two sessions and seemed to send me into a running spiral.

Intervals – 5x1K with 3-min standing recovery

Below are the results of the 5x1K with 3-min standing recovery, plus I’ve included Christmas Day parkrun to illustrate how my running looked without the recoveries and what I was trying to improve upon. It’s noticeable that my first intervals weren’t much faster than the parkrun.

18-Jan3:424:013:504:063:49
25-Jan3:433:543:493:593:50

You can see for the first three weeks, the first kilometre was still only capable of being run in around 3:55 and then on 11-Jan, I clocked 3:44 and went faster the following weeks. What’s noticeable is how slow the other intervals were on the 11th and I think this is because my legs had dug out more fast-twitch muscle which was producing more lactate and this then made it harder to run the following intervals especially the uphills. Over the next couple of weeks, the body began to adapt so either less lactate was produced or it was cleared / tolerated by the body allowing the later efforts to speed up.

The highlight of running a kilometre in 3:42 is it’s the same pace as my 800m a year ago. Not only did I run 200m further on this training effort but I was then able to do further efforts three minutes later. Remembering back to my original time trial, I did jog immediately after but my breathing was rasping away and my lungs burning for the next fifteen minutes and beyond.

Long runs – 11.7 miles every Sunday

I have a standard long run to Broadstone which I’ve been running fasted (no breakfast) at about 7am. In late November, I clocked my quickest ever time of 1:29:06 (7:38/mile) with an average heart-rate of 151.  The following weeks I prepared for Christchurch 10K so didn’t run it again until December 19. This came in at 1hr32 and set a baseline for where training was about to go. The start of January saw my body absolutely crash with heavy legs after Christmas Day parkrun and two sessions of intervals. Just too much and I needed recovery hence a 1hr45 run where heart-rate barely got out of the fat-burning zone. As the weeks passed, the long run quickened up until I ran a course PB on January 30. The variability of the long run highlights how when you move the body towards faster work, the endurance drops off.

Steady run – 7.4 miles

My second workout of the week has been a Steady run usually on a Thursday. I hadn’t run this route in a while but my previous best ever was 56:25 set years ago. Often it takes over an hour if I’m doing an easy run.

For the Steady I would head out and push up to an upper aerobic feel – what I feel is marathon pace intensity and just hang on, never pushing it. It’s a route with a long uphill at mile 3, heads back down for faster miles at 4 & 5 before a gradual uphill to home.

I was pleased when I ran a course PB two days after the first set of intervals but when I overloaded in the next few days, I took it easy the following week. Once my legs were back, I began to see the same improvement and benefits that I’ve experienced on my long runs.

The run on January 27 was done with an extra day of recovery, on the Friday rather than the usual Thursday. I’m sure it helped and I was really pleased to achieve three sub-7 miles during the run – admittedly on downhill miles! It’s a long time, if ever, that I’ve run those sorts of splits on a local route outside of a race or workout.

Drills and strides

These have continued twice weekly and, as I’ve said before, they seem to have made a massive improvement to my running form. I feel I’m beginning to skim over the ground with all my effort applying horizontally rather than a bouncy, up and down stride which you see in many runners.

I added in a C-skip at the start of January as the B-skips had become coordinated and I was no longer having to break them down into smaller parts. C-skips are what most people would think of as “butt kicks” (heel flicking up to kick the backside) and they unlocked some of the tightness in the quads. But there was a small downside as the increased efficiency began to put a strain on previously unused muscles and I’ve been struggling with a painful left glute which then began to extend down into the left ankle area. Nothing terrible and never a problem when I’ve been running but flaring up during long periods of sitting.

On the week of 6-Jan when I didn’t do the Steady run, it was because I ran the intervals on the Wednesday to give myself extra recovery. The following day, after doing drills, I ran one 200m to get an idea of where I was at and it came in at 35.81secs. The fastest since I began 800m training and close to my best recorded ever. The cadence was consistent, starting up at 206 before dropping slightly to 204 then 202 – but it was very smooth. I was pleased with it considering I’d run hard intervals the day before.

January over, looking forward to February

So that’s how January’s training has gone. The only negative is I only attempted one fast parkrun on 22 January and that came in at a disappointing 21:19 at Upton House, over twenty seconds slower than my PB there. But I know I’d been training hard and my legs were recovering from it. The fastest kilometre was only 4:05 which is notably slower than the sub 3:45 I was running in training.

While I’d like to have continued with the 5x1K to see how they evolve, I’ve decided to take training in a slightly different direction for February and March as I’m intending to run the Bournemouth Bay Half marathon on April 3. So I’m going to fill in the gaps with some 10K-paced work on the next 2-3 Tuesdays then switch those workouts to half-marathon paced work and looking to build the endurance to support it for the longer distance race. That will round off my winter training and set me up for getting back to 800m work in the spring.

Update on my 800m training – Nov-Dec 2021

Traditional winter training for middle-distance runners is a combination of building endurance and running cross-country. In my case, I’ve replaced cross-country with an all-out parkrun effort every couple of weeks.

After my last 800m time trial (2:49) in October, I took a recovery week and then began the endurance work. Using a fortnightly cycle the plan was to do two Steady runs (Tuesday and Friday) and a long run on Sunday on week one; a Steady run on the Tuesday and a faster-than-Recovery paced run on Thursday with the fast parkrun on Saturday. It worked quite well and my first three parkruns came in at 21:20 (Oct 23rd) and 20:55 (Nov 6th) at Upton House then a road trip to The Great Field parkrun (Nov 20th) where I ran 20:26.

With Christchurch 10K on December 12th I wasn’t planning to do specific training other than to taper and run on fresh legs. I’d planned to run one more fast parkrun between Dorchester and the race but Storm Arwen hit so I replaced it with some cruise intervals.

The 10K was a little disappointing as I went in expecting to be somewhere in the 41-42min range and ended up clocking 42:25. Not a terrible time by any means but my legs never felt good. I have a feeling I killed them in the preceding week by running a low volume of 200s and 400s. On the Friday (3x400m), Tuesday (2x400m) and Thursday (2x200m). That really is a low volume but perhaps I ran them too fast as I originally was aiming to hit 5-10K pace and the 200s came in at 37s which is faster than my 800 pace. That was a fun session as I ran it at the cricket pitch. Groups of college sixth formers on their lunch breaks were dotted around and they began heckling and cheering me on!

Since the 10K, I ran another 21:01 at Upton House and then on Christmas Day on the flats of Poole, I was among 798 runners as I ripped round to finish in 20:11. Touching distance of being back under twenty minutes.


After giving the legs a week to recover from the 10K, I decided I’m lacking decent aerobic capacity. On the parkruns and race I’ve barely been able to run quicker than 3:55 for a km. In 2020 I could run 3:48, two years ago I was hitting 3:45 and five years ago I was close to 3:30. The endurance training has been good but it’s been to the detriment of my aerobic speed. Even my top-end speed isn’t great and I believe this has contributed to the disappointing 800m time trials this year. I’ve noticed as my leg speed has disappeared so has the size of my quads – at least a couple of inches smaller than they were.

The consequence is I’ve begun running my old favourite session – 5x1K with 3-min recovery. It’s a great combination of distance, pushing the aerobic capacity and improving lactate clearance and tolerance.

The endurance training itself has begun to look great. I’m running twelve mile Sunday runs at sub-8 pace – close to 1hr30 most weeks. But also my recovery runs have got faster despite me keeping them easy wherever possible. This has really set me in position to build the speed side with the kilometre intervals and I’m hopeful this will have me close to nineteen minutes at parkrun by end of January.


Supplemental to the running, I’ve been finding sprint drills and strength work have been highly beneficial. The drills have been great in identifying inefficient running form and after two weekly sessions for two months, I’m finding the improved posture and muscle activation are beginning to bleed into my runs. Most significantly I’m start to get the feel for how to sprint and this can only be a good thing for my 800m time.

The squat work has strengthened up my legs but also the muscles in the hips and glutes. It highlighted a weakness in the left glute on the outside which was clearly not contributing to my running. As it strengthened up, it began to fire during runs and, in the long term, I’m expecting it to make a difference. On the negative side, I did too much squatting too soon and after about three weeks began to find my legs were getting sore so I stopped to let them recover for a week.

It’s been a useful two months, especially as I’ve taken over a minute off my parkrun time with my best time in four years at 20:11. I’m intending to stay with this plan through early 2022 and maybe run Bournemouth Bay half marathon in the spring. I’m sure a big part of improving my 800m time is going to be improving my aerobic capacity with the 5x1K intervals – I’ve really allowed my leg strength to drop in favour of efficiency the past few years.

Update on my 800m training – Oct 2021

The time had come to run another 800m time trial and find out whether JackD’s plan was working. 

A quick recap – last December I ran 2:58 to set a baseline. In April, after following Jack’s plan for a cycle, it reduced by only five seconds to 2:55. I then did six weeks of endurance training and it reduced a little more to 2:53 in early June. This was where I started my second cycle of Jack’s training from. The summer was then spent following the plan as best possible allowing for hamstring strain in July and a fast parkrun in August. I did all but three of the scheduled sessions.

So here I was back at Poole Park and having gone through my usual pre-run routines, this time I ran 2:50, maybe 2:49. Still no significant improvement. This was highly disappointing given I thought I was capable of breaking 2:40. Back in early September I ran 1:58 for 600 in training – that’s 2:40 pace so I should have been faster on the time trial. But it wasn’t to be. Realistically when I got to the October time trial I’d already passed my peak and was on the way downwards hence the poor showing on the day.

There’s no doubt I’ve generally got faster and fitter from the training but it’s not resulting in faster times over 800. If anything all I’ve done is brought the average of training up. I’ve not got significantly faster in the top-end speed – I ran 37-38secs for the first 200m of this time trial, back in December it was 39-40 secs. That two second per 200m improvement simply reflects what’s happened in the time trials.

World class 800m runners are easily capable of running twenty-five seconds for 200m – even the women. I’m nowhere close to that, maybe thirty-five seconds at best. So I’ve got to find a way to improve top-end speed because if you start running 200 quicker then the subsequent sections all get quicker. Even with a drop-off 400 is covered in under a minute and so on.

Endurance rebuild

Following the time trial, I knew I needed to let my legs recover. I spent a week doing very easy jogging. And that’s all it was – jogging. I’ve come to realise that when I’m past my peak it’s because my body has begun switching Intermediate fast-twitch fibres over to anaerobic mechanism and these can only be rebuilt through endurance training – lots of easy running, no speedwork.

My first Sunday run of the rebuild saw my heart-rate barely going over 130bpm during the entire run. Yet it still felt effortful in its own way which always highlights a drop in endurance. In the following days the pace picked up but I was still only barely running 8-min/mile until my legs came back. Yet by end of month I was beginning to see some miles closer to seven minutes and even putting in a couple of 6:50s on Steady runs. My final Sunday long run of the month was close to where I’d been in late August. Theoretically I could have picked up the 800 training again but I want to spend the winter on endurance as all world-class runners have a large aerobic base.

Form drills

Recognising my top-end speed isn’t good enough, I started looking at how to improve my general sprint speed without resorting to hillwork which usually overpowers my endurance. As I detailed in Stride Length, I’ve been thinking about how to improve this and started doing more drillwork – marching, A-skips, B-skips and straight leg bounding – to try and improve my running form. And boy, did it improve.

From the first day of drills I could feel my left glute hasn’t been working, my knees haven’t been lifting enough and my lower legs (the calf) have been inhibited in extending the stride. That inhibition has come from previous attempts to improve form where I looked to get rid of heel striking. There is so much conflicting information out there, most of it by people who are interested in very, long distance running rather than speed.

Given it’s ten minutes after an easy run twice per week, I’ve really enjoyed doing the drill work. I think it’s a new challenge and I can feel it’s going to help. The disappointment of the time trial has quickly gone.

Pistol squats

When I was researching exactly how to do sprint drills I came across heptathete Chari Hawkins doing a pistol squat.

Trying one I couldn’t get anywhere close even hanging onto my kitchen counter! It occurs to me that at the bottom of the pistol squat is very much the sort of position sprinters push out of from the start blocks. Developing it must be useful for getting faster especially as Chari Hawkins can run a 24.4sec 200m.

So I’ve begun doing daily squat work and discovered my left leg is weaker than my right. Much of that is related to muscles around the left hip which has impacted my running stride in the past. Doing the squat work has begun to strengthen this.

Combined with the drill work, my running form has changed massively in a couple of weeks. I’m feeling stronger and more balanced in my running. I’m sure my stride length is increasing simply because I have a stronger push off.

Coming up

The next block of dedicated 800m training is a long way off. I’m going to use this winter to build endurance. I feel that’s also holding me back. The best 800m runners in the world all have big aerobic systems which reflects in their easy runs being in the 6-7min/mile range – currently that’s top end aerobic running for me; not easy. I need to build mine up while maintaining contact with my speed.

I’m hoping to maintain speed through a fortnightly fast parkrun (as well as drills and strides). It’s a long time since I went to parkrun and ran fast regularly. I feel sometimes I’ve got so focused on training that I don’t get the reward of actually racing fast. My first fast parkrun on Oct 23rd came in at 21:20 at Upton House. While it was a four second PB over August, I know there’s much more to come as the legs were fatigued from a big week of running.

The other thing I’m looking forward to is Christchurch 10K in mid-December. While I’m not intending to do any specific 10K training for it, I am focusing on it and will taper for it. After that I will probably look to run a decent half-marathon next spring before resuming 800m training again. It’s all a long way off and yet it’ll fly by!
