I love doing that!! totally my thing!! haha. I wish I looked that clean after a race..
I take off my helmet and goggles, I have dirt caked on my face like no other.. and I'm spittin' out dirt clods and crap... It's not pretty. haha. and how dirt ends up getting behind my chest protector, undershirt AND jersey... is incredible haha.
I think it may have something to do with the air gaps and open spaces that men don't generally have on the chest...
