The longest training ride was like yours, but on a Diamondback mountainbike! It was a blast the first day was the hardest the rest just fall in place. I ate like a pig as my body was in need of more and more energy. I rode one day with a guy dressed as a nun with with the the big flying nun hat and black clunky shoes. Plus take a tip from the century riders and do the two finger swipe every morning. The aid station should have big jug of petroleum jelly. Another guy was riding along crying tears as his ass was bleeding form a shitty seat and diaper rash cream! He did better after we got him to a checkpoint. Great challenge and worthy cause. I'm in.
