Restrooms can be few and far between in some of the long, long ultramarathons I do. Many people of both sexes will answer the call of nature not very far off the trail. When you're 12 hours into a race in the middle of nowhere, tired, sore and often nauseated, and you have 25 miles to go, modesty goes out the window.

And I'll tell you, I've seen some women whose "pit stops" are almost as quick as the guys!!!! Maybe it's a matter of practice. I even saw one gal pee standing up (yes I'm sure she was a lady) but don't ask me how.
