Interesting article in Bicycling Nov 09 about Adam Leibovitz U.S. bicycling champion. He battled ADHD for years with medications, and then discovered bicycling. He says "When I was off the meds and rode a lot, I'd feel great" When I'd take rest weeks I'd be bouncing off the walls."
Also he says, "I never feel more serene-or more focused then after a good, hard ride."
Well I gotta go, like those close to me know, I need my "meds", my day on the bike.
