I've always wondered about the validity of these figures:

(snip) Because there is obviously a vast difference in how people both walk and bicycle. I ride a lot, and at least 90% of the time at a fairly good pace with elevated heart rate, breathing, etc. OTOH, when I walk I never experience that sort of "pump", so I have a hard time seeing how I burn less calories riding than walking. I get there faster on a bike, but with more effort. I also observe many people however who ride much more leisurely, often coasting whenever possible, while I usually pump just as fast downhill (unless it's very steep, which it isn't around here). So I wonder which type of rider and walker they measured? -- Harmon Seaver CyberShamanix http://www.cybershamanix.com ------------------------ Yahoo!
