I feel like I could be a fast sprinter, but I don't know how fast is fast. Without a lead out, and at the end of my 30 mile loop, I am able to sprint up to 38MPH. I feel like this is my max sprint speed after an average ride. I have seen 41.X MPH on a few training intervals, but that is always with fresh legs.

Anyone else want to toss out there sprint speeds?
