Ok I've got a question on sprinting speed. First of all, I am small (5' 10" 140 lbs). Anyways, last week in the middle of an easy ride I did a few sprints, just to see ballpark what speed I could get up to. This was with a slight tailwind, but not too strong. I was only able to get up to 32.5 mph!!! Dang I mean can't Lance do close to that speed for an hour?

What kind of speeds am I going to need to get up to in order to contest sprinters in the end of a race?
