It's a very pretty ride, although I haven't ridden it in a few years. I'm usually working it, since it's my club's big ride. It's hillier than Cinderella, all the routes except the 35 mile option go up to Gilroy Hot Springs (one of jobob's favorite rides.....) Although I hear there may be some route changes this year, so no guarantees!
Cinderella is relatively flat, you may be able to do it. Heck, I just started training for it last week - a whole 20 miles on Saturday.
