The ride is April 28th & 29th so we will have to get to training pretty quickly for the ride, I have done it years ago when I was in better shape so I'm sure I can get back to that level. She does cycling classes twice a week which I know is nowhere close to the real thing but I would think it would help with the butt callous. It's probably not the best idea to do for a new rider but hey why not shoot for the moon. I am just trying to get her a good bike that can handle the 175 mile ride so I'm not sure if I should go hybrid that will still be comfortable for daily cruises as well as a stretch for a distance ride or if I should go straight road bike that can handle the 175 mile ride with no problems.
