I've thought about this a lot recently, and something I often forget to do pre-ride is to stretch. I think a lot of people feel that this is unnecessary, because they figure the workout will limber them up on its own, but I don't think that way. From my experience, stretching the leg muscles (quads, calves, etc.) and even the upper body (arm muscles mainly), it tends to give you greater flexibility and, as I've been told, somewhat better circulation. I think I'll try to remember it next time I ride. What are your thoughts on this process for ride-prep?
