The other day my cousin and I rode out Rails & Trails..........mind you now I have not been on my bike for a couple of years. We did 13 miles...........man was my butt sore!!!
We both had a spill each..........both times just standing still LOL............we were trying to get off on the side where the gravel was and lost our footing. She had just a tiny scrape........I had blood running down the leg. I told her later we did not wreck............we just laid down.....FAST & HARD!!! LOL Was a beautiful day for a ride and glad I did it...............not sore the next day at all and leg not even sore............just not pretty looking. Perhaps do it again............not sure on that...............I would like to get a BIGGER seat to see if that helps.............it's a bigger seat or get a smaller butt...........the seat will happen quicker that the small butt!!
My sister was able to get a bigger seat for her bike. I think she went to a bike shop and special ordered it. But she is able to bike for miles and not have a sore butt.
