You should go to a professional bike fitter in your area.
Actually, this was after getting fitted onto the 56 and not liking the results (namely the way-long stem and hanging the saddle off of the very front of its rails; "It won't fail catastrophically, it'll just break," the fitter said..

), then exchanging for the 60 right there in the store that evening.
On the smaller bike, I'd hurt so bad that I'd turn home not long after simply getting warmed up. By now, though, I've only stopped riding when I've either run out of time, gone where I wanted to go, or just gotten tired of it.
