I have coached and counseled a number of serious cyclists. I help them to learn how to be focused, confident, energetic and ready to endure and to compete.
There are many tips, programs and books for riders at www.StayInTheZone.com
Also, you have to get the right bike and the right equipment.
There is a super bike shop in Ridgefield, New Jersey. They guys who run in are super. They fit you carefully and the prices are right.
I have bought about ten bikes there myself. Check out The Cosmic Wheel.
