Update on my 800m training – June-July 2021

I’m now six weeks into the second time round with my 800m training. My first go-round, following a Jack Daniel’s plan, lasted from December to May and didn’t provide great results as my 800 time only improved from 2min58 to 2min53. But I knew I was running faster, felt fitter and hoped a second go-around would show better results.

This training block is full of intervals ranging from 200-600m in length. As you’ll see in the stats the vast majority are short with just four 600s planned. Last time I was aiming to run at 48sec/200m but later realised I should have been using 48½ which I could only just scrape on the 400s and 600s.

I’ve been working to 47sec/200m which is the training for a 2:52 800m. Trouble is, I’ve been averaging 43s for 200m, 1:31 for 400m and 2:15 for 600m. It seems like this reflects the discrepancy between my time trials and how I actually felt my fitness had been progressing.

More speed

Last time I tried to be accurate with my interval efforts – not going fast than necessary but always hitting target. This time I’ve thrown caution to the wind and allowed myself to run without holding back. That’s not to say I’ve gone all-out, I haven’t; just not held back.

Some interval stats for those who love them!

I’ve also introduced 8 strides of 10secs after my Friday morning recovery run. Ideally Jack would have me doing these on two of my recovery days but I didn’t want to undermine my aerobic base too much. Last time around, I didn’t do any; this time I’m doing one set. Next time around, if everything is going well, I’ll introduce the other day.

I suspect it’s (a lack of) this faster running that was holding my 800m time back in the past. I’m beginning to see my fastest pace come down from 5min/miling to 4:30/mile during strides and this may partly be down to the limitations of how quickly my GPS watch can produce an accurate pace.

Injury risk

The bigger danger is pushing too hard may lead to injury and it happened. I suffered a minor hamstring issue in week 5. It was the final 200 of a session that had already totalled 2,800m, and when I’m feeling good as I was, I tend to like to finish strongly; so  I pumped my legs as hard as I could but felt a tightening in the right hamstring and it began to knot. I eased off, finished out the effort and jogged home.

I was fortunate to have this happen on the Thursday as it gave me five days to recover before my next set of intervals. I still ran on the days in between and by the Tuesday my legs were feeling great during the warm-up. I eased into the efforts but by the 4th 200 I was getting a sense I might not last. The next 400m I felt some tightening and on the next it was even more notable so I backed out and jogged home. That was last week and I missed the final day of intervals opting to keep runs easy and never push them along. I did a couple of strides on my Sunday long run and that seem to confirm the hammy is ok so I’ll resume training to the plan.

Long runs and mileage

The switch from a block of pure endurance work to repicking up speed work left the legs struggling on the general runs but it didn’t last past the first couple of weeks. But the introduction of the strides also sapped the legs going into the Sunday and so I haven’t seen much progress on their pace, they’re still around the same pace as last time around.

The six weeks of training I’ve done so far have resulted in 41.3, 45.1, 44.7, 45.7, 42.0, 43.8 miles.

Running form

Since April, I’ve been looking at how sprinters run and trying to apply some of their techniques and drills to my own running. The strides have been useful for this and I’ve particularly been focused on minimising hip rotation through better knee lift. I seem to be getting higher cadences on many runs and that’s going to be an important part of getting faster. The higher cadence corresponds with a concomitant rise in my glutes doing the work.


Once again I’ve really enjoyed this block of training. Getting out and running fast is fun especially as I’ve been finding it so easy to hit target. The hamstring injury is frustrating but I’m hoping that with the next phase of training being longer intervals at a slower pace that it’ll survive. I can run on it as long as I don’t overdo the forces going through it.

In the next phase, I’m meant to up my paces for fast efforts by a 1-sec/200m but, given I’ve been finding it so easy, I’m going to compromise by adding 2-secs so that I’ll actually be aiming for 45s per 200 which is what I’ve usually been running them at. This isn’t recommended as you should train at paces that relate to proven times and I haven’t actually run a 2:48 800 that would justify it.

Parkrun is also due to restart at the end of July and I’d like to attend. I’m not going to run hard every week but I’d like to see where I’m after all this training. I feel like I’m close to sub-20 form. It’ll mean dropping a workout, which isn’t ideal when you’re following a plan, but a fast parkrun will still have benefits.

But the priority is keeping the hamstring healthy.
