That's what I noticed. The place to learn how to sprint is on the road. Accelerating mass on the road and increasing power demands at the cube of the speed is a whole different thing. Moving the bike...

If it's pee and it's cold, just go in your bibs. No harm done. I once loaned a bib-wearng rider a pair of warmer socks. He had to take them home and launder them before returning.
