Nature break?

[Tri Girl]

I saw a picture from last year's Tour that had riders as far as the eye could see lining both sides of the road taking care of business. They didn't even dismount their bikes- just stopped to do their thing. I found it to be hilarious.
Let's see if I can find it:

This is from CSC's website called: Get up to Speed on the Tour. It answers a lot of questions.

How do riders take bathroom breaks?

With longer stages lasting up to seven hours, it’s inevitable that nature calls.

Riders try to go to the bathroom before the start of the stage. When the need for a bathroom stop is urgent, riders will pull off the side of the road to take care of business. Sometimes in longer stages the bunch will organize a bathroom break to allow several riders to stop while the remainder of the bunch rides slowly until they catch up.

Etiquette calls for riders not to attack when another rider is answering nature’s call. Sometimes, riders will even ease off the back of the bunch and take care of business without even stopping, a delicate, sometimes imprecise maneuver.
