Well after 3 months of trying to be a self taught cyclist, I figured out that the key to a good ride(for me) is constant rpm not speed. Went out today with the express intent to try to maintain a steady cadence. Rode 13 miles, used whatever gear it took to maintain, paid no attention to speed and at the end of it my average speed was the same as when I was fretting over speed. I think I was trying to spin too fast. I felt a lot better too, didn't kill myself. Think Ill spend the next 30 days riding 13-15 miles at a constant rpm!!
