To add to the addictive nature of cycling, in a few weeks people will tell you that you are looking better than ever. You will be working with someone helping you and they will need a rest, but you will still have energy and stamina. You will try not to gloat, but you will feel very good inside. And, you will find yourself just feeling good when you finish a ride. Fatigue eventually sets in and that keeps you from riding all of the time.
