Tour de France 2010

I wonder if anyone could help me, you see, I was looking at all those chaps, five odd hours and ten odd litres, and no peepee stops?
Are they peeing down their own legs as they ride? Or wear nappies? Or do they sweat enough not to need peepee stops?

They have 'comfort breaks' aka piss stops by the roadside. It's usually not on TV.. for obvious reasons.
