This was a question for my “Ask a Pro” column in Velo magazine, but the editors thought it was a little dirty, so they gave me permission to put it on my site instead.
You don’t have first-hand knowledge of this, but I thought you might know, anyway. I’ve seen men pee off the bike during races with a push from their teammates, but what do women do when they have to go during a race?
Indeed, as a male, this question is foreign to me, but I asked around for a good answer. From what I’ve gathered, women have some sort front butt, and they poop babies out of it. I forget what they call it or how it works, exactly, but I hope this helps answer your question.
