Today I go to the doc and see if he will give me a shot in the knee to help heal tendonitis I got a week ago Saturday from a case of the "stupids". I did a 55 mile ride with some friends at a moderate pace through rollers and changed my gearing from 70 to 66 which was perfect for the ride except I jamed up a lot of rollers seated where with the 70 I would have stood. Lessons Learned!
