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.
