Racing 10,000 metres on the track
On Thursday I lined up with 28 other runners, all with the same goal: to run 25 laps of the track as fast as we could. Initially I followed Burkie, as his even-pacing is legendary and I thought he'd run around 45 minutes. Pete was running just behind, with Kelley and Mick ahead, while the fast-starting Bronwyn ran with Craig — these two quickly splitting away from our group. Following Burkie, I ran through the first k in 4:28 and the second in 4:28. Perfect! Or so I thought. I started losing contact with Burkie as we ran up the back straight to the 3k mark. 4:37 for that k — markedly slower. The rest of the race was pretty much a grind. Pete overtook just before the 5k mark (23:11) and ran a negative split, finishing in 45:59. I continued to fade, running the second half in 24:36, for a finish time of 47:46.96. Burkie finished just behind Pete in 46:07.
My average heart-rate for the race was 147 and it was lower in the second half than the first, which is unusual for a track race. For the same race in 2010 I ran 45:57 at an average heart-rate of 153. I'm slightly confused about this. I suspect my legs weren't fresh enough on Thursday evening to run at a speed that would have pushed my HR into a higher zone. Between now and my goal 5000 on 29 March I'll be running 'training' races pretty much weekly. I may turn some of those into extended training sessions as suggested by Sling in the comments on my last post.
