On climbs I just realize how much I appreciate the opportunity to get the exercise as most people (including myself) are so consumed with the stresses of everyday life (work, family, bills etc...) that we neglect our health with lack of exercise. My commute to work is mostly downhill with one climb. On my return it is mostly uphill the whole way. I use the hills as a stress reliever not a stress inducer by thinking about the benefit that the hill is giving me. I cant begin to tell you how riding has made me look and feel. When it gets really tough I imagine myself on some climb in one of the races I saw on the last OLN Cyclism Sunday. To tell the truth, if you are lucky enough to get in a good climb everyday, its the best exercise, going and the ride down the otherside is the payoff.
