The ski jumps at Calgary
I started with the intention of running something close to 21 minutes (I would have been happy with 21:30). After 500 metres or so I thought I had an achievable pace going and was feeling good. Then Roger (20:27) and Geoff (21:20) glided past. I ran more or less with Heidi for 3k, and was managing to hold a gap of 30 metres or so to a couple of young girls from my club, Lili and Caitlin.
The last 2k was not a pretty sight as Heidi and the two girls disappeared over the horizon. I've made a chart of kilometre splits — it dramatically shows my wheels falling off one by one. My race looks like the profile of one of the big ski jumps at Calgary. I know because I took the lift to the top of the biggest one in 2003.
The other two lines on the chart show a better way to race a 5k. The middle one is from my all-time 5000m PB. The bottom line shows the splits Ron Clarke ran in 1966 on his way to a World Record. I'd like to run an M50 PB this coming track season. To do that, I need something under 4:15 kilometres. I'm inclined to keep my starts like the lower slopes of the Calgary ski jump, and hopefully flatten it out as my fitness and speed improves.
