Thanks for the tips. For me, upper body and core work is very important. I've had 2 bouts of upper back/neck pain and 1 bout of shoulder tendinitis in the past 3 years. I have to make sure I do specific exercises to keep my upper body strong for fear that I will have more overuse/postural injuries and problems. I try not to overdo it and plan on keeping the upper body stuff on recovery days or lighter spinning days. I don't use super heavy weights and often include therabands into the workout. I don't work out my legs with weights during cycling season.

Right now I am at 40 miles for my "long" ride - which is not too difficult for me since I was doing that amount last year and got up to 60. I think doing a century will be hard and a little painful, but I feel good about doing it. I just hope I get a dry day that isn't too chilly. I do live in Michigan afterall!
