I bought a Trek 2.3 a month or so ago to get into shape. 53 years old, carrying 30 pounds or so I don't need, used to run but messed up my knee. I need a challenge..to race..to tour. I enrolled in a Cycle Camp that is going over basic bike maintenance and group riding skills. Not going far, but learning alot. Longest ride has been 16 miles (I know, not much..but for me it is. Today we went and did some hills...damn near killed me but I got down into my granny gear and got up. It felt great! I think that I am hooked. My legs are stiff and I'm sure they will be sore as hell tomorrow...but it was worth it.
