It's even in the rules somewhere!
(but I think after even 10 hours on the bike, some folks will get pretty stinky.
Not ladies of course - they merely glow).
I might get a doctors certificate that I neither snore nor fart - i then expect to be allowed entry to the Unisex Quiet Dorm. (it's only a small minority that snore properly, but sadly they really do ruin it for the rest! Earplugs pretty much do the job for me, especially if I have a few 100km in my legs. )
