Yesterday I finished reading Mike Heft on Wheels: A Field Guide to Doing a 180 (2004, NY: Harmony Books) and it's both a great read and maddening at the same time! Overall it's very well written, moving from past to present, with glimpses of the past. It really strikes home with me as I work towards regaining my fitness, reading about this 255 pound smoker and heavy drinker use cycling to get fit and lean (trading one obsession for another). Unfortunately, the story is marred at times by some heavy-handed self pity, which really break up the flow, but it doesn't detract enough to stop it from being a good read. Recommended.
