No need to be afraid, those numbers look good to me and it seems you have 25 years on me. I just ask to see how much of a wimp I maybe. Yesterday I rode 20 miles, AVS 13.1, and TM was 1:31:41. There was wind and hills too. My fastest decent was 28.1 MPH. I don't know were I compare to more serious cyclist. My bicycle is an 1983 mixte style Schwinn le tour. It does need some work, but seems good enough to get the job done. I thought I needed a good road bike to help improve my performance or maybe am I just looking for excuses. In the end it's all about the fun anyway.
