Professional cyclists. Do the stop the bike and pee and lose some time? Do they pee while biking? Down the road or in used bidon? Dipers? Or they have superhuman bladder and do not pee at all? Mind you they drink gallons of liquids and they can’t just sweat out all of that.
And of course, there are some other sports that this could be a problem…
Paula Radcliffe stopped to relive herself during the London Marathon recently and, IIRC, during an interview with Frank Skinner she admitted to having defecated during a race as she didn’t have time to stop, grim business to be sure!!
Hehe. Back when I raced in college I recall the group I was in passing the women’s peloton. They had all agreed to stop and take a potty break and the riders were either squatting on the side of the road or standing around waiting for their teammates and competitors to finish up.
This was on a road in a rural area near Reno, so it’s not like there was anyone other then cyclists around to see it…
I’ve read a story of Greg LeMond racing when sick with, well #4 running down his leg. I’m not sure if it was the TdF or another stage race but I’m pretty sure it was in Europe. Those guys are hardcore.
I’m not sure of how it is in all conditions, but when I rode in sweltering heat and was pretty much constantly sweating, I really never felt the need to urinate. I was at one race and I kept riding (off course, of course) after I had already finished, and for the 6 or so hours we were at the location I never had to relieve myself.
Considering the output of their bodies, I imagine they could go for quite a while without needing a bathroom break. Thinking back to redoing my brother’s roof during a New Mexico summer, I drank water and whatever else my sister-in-law brought up the ladder, but could go all day without a whiz moment.
I drove in a 300 lap stock car enduro race once. The whole thing took about 4 hours and I never had the urge to go the whole race. But about 15 minutes after it ended, nature called in a big way.
FYI, a stock car enduro involves taking street legal cars, making minimal changes, usually only for safety, placing all the cars on the track and dropping the green flag. The race ends when the first car completes 300 laps. The race I ran started 56 cars, about half were still running at the end. I ran 284 laps and finished 11th driving a 61 Chevy Biscayne.
it’s not surprising that they wouldn’t have overwhelming urges during long periods of physical activity, if I’m remembering my biopsychology correctly.
the autonomic nervous system, which basically controls involuntary stuff in the body, has two divisions, sympathetic and parasympathetic, and basically when one is very active the other is not. the sympathetic division is pretty much your “fight-or-flight”, adrenaline-pumping, high-physical-activity division, whereas your parasympathetic is your default, boring, sitting around digesting food and not needing much oxygen to the tissues division. so if you’re cycling, or fighting, or running from a bear, energy is directed away from things like digestion and urine production, and towards pumping your heart faster, dilating your pupils, breaking down glycogen in your muscles, et cetera.
