There is a very small number of cyclists (99% guys I'm guessing) that are willing to beat the crap out of themselves for whatever personal reason (I'm not judging) on the simple bicycles machine riding endless hard, mean, soul searching, hours of angst and pain, miles. Very very few women are willing to go that route. Maybe 1%? Personally speaking, we're just not into that sort .......
I feel extremely fortunate to be married to one of those 1%!
