Overall, I thought it was a very nice ride and I'm looking forward to doing it again. The 30 miler was actually over 35 and with my mistake, I ended up going a bit over 37. I was actually happy about this since it set a personal record. I was suprised there was only one rest stop on this route. It wasn't an issue for me but I could see 35 miles with only one rest stop being real tough on someone who has never even tried close to 35 miles before.
Regarding CV bikes, I saw a guy on an early 80's Fuji and complimented him on it. I almost went with my CV Fuji but felt for my first benefit ride I wanted the modern shifting and wider tires offered on my CX bike.
