The elbow will be beautiful before it is over, but nothing serious. and my shoulder a little sore. It was worth itAt least I finally figureed out what I've been doing wrong when shifting my Trek. Basically I've been teaching myself, and that can be interesting.
My personal trainer thought it interesting that the person I hired to give me a couple of riding lessons early on never really focused on how to shift. She gave me a very complex diagram from Sheldon Brown's site, but we didn't go over the basics and I didn't know enough to know what to ask. My trainer rectified that yesterday and he focused on my shifting and basics of riding in traffic. It was fun, and very needed.
I have been surprised at the amount of vibration that reaches the handlebars from rough roads though - yesterday I hit a patch so rough that my feet came off the pedalsI know my LHT would have handled that patch differently, but it isn't fair to compare a fitness/flat-bar road bike with a steel touring bike.
