Speed work

After last week's hill reps, I'm now confident I can run (or rather walk, slowly) up Scafell. However, I'm less confident that I can keep my legs moving fast enough to descend quickly. This was highlighted in the race on Sunday when I lost ground on the flat and lost loads of ground on the descent.

So tonight, instead of hill reps, it was sprint reps. This is even more tiring. I think my flat course is about 250 metres, but it's through a sheep field, so it's not exactly perfect track training. I did 8 reps flat out before feeling completely broken. It did feel good to be running quickly again.

Whenever I do sprint sessions I am reminded how good proper runners are. I probably was close to averaging about 4:10 minute/mile pace for 250 metres. At the end of each rep, my heart rate was 165 (from 140 at the start). And yet there are guys who can run this pace for quite a few miles. Amazing.
