I am proud to announce that I did my very first 25 Mile ride Saturday!! It was the Crane Cruise in Medaryville IN. My daughter went with me, and rode my husband's bike. Both are Specialized AT bikes. Not built for speed, so I always ASSUMED my 10 mph max speed was partly due to the bike. well, since my daughter (and everyone else, including 2 people on tandems with children on the back), were passing me like I was sitting still, I realized, I NEED TO GO FASTER!!! So, my goals are 15 mph, and a 50 Mile ride next spring. Now, any advice on HOW to accomplish this?
