That's a fairly substantial if in my case - but Running Times has an online article on running recovery tricks that you should look over if you're in the middle of your track season. Some you probably already do, some you won't, and a couple might be worth trying. Not sure if I'm up for liquid nitrogen - and they sound a little hesitant, too. I was a little surprised at the bit about warm-ups doing more to prevent muscle soreness than cool-downs. Since my race pace is a warm-up, I should be pretty darn safe.
