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.
