Running today, with intermittent walking, all on the track at Monstro's university. Here's how it broke down:

stretch

warm up: 800 m with two flat-out 100m straightaways

stretch

workout: 800m with four flat-out 100m straightaways, walking briskly on the curves.

cooldown: 400m walk, stretching

There was a guy walking in lane one (big pet peeve of mine): when I started he was half a lap ahead of me. Before I finished my second warm-up lap, I'd passed him. Boo-yah!

My left knee is hurting and my left leg is feeling tight. Time for a massage!
