I am new to the forum and need some advice. I have been cycling for 3 years now. This year I am training to ride in the MS150, which is a 170 mile, 2-day ride from Houston to Austin. This past weekend I rode a 70 mile ride and a 40 mile ride to prepare my body for riding two days in a row. I was sore in the usual places, however, I am also extremely sore on my tail bone. Since I that part doesn't touch the seat, I am curious if anyone has had this problem and if so, what they did to alleviate it. It is quite painful and uncomfortable. Any advice anyone can give would be greatly appreciated!
