I like this question ! I hope people keep posting , it ' s really interesting to read . Much of the hamster brain I go through on a bike comes down to , Why do I bike ? and broader extrapolations of that question . Depending on the day estimating how many pedal strokes I made on the last tour , how many I ' ll make on the current tour something on the order of 1 million per month of touring , if I remember right . Surely there must be a more comfortable seat . Going through a city big enough to have a commuter population Yeah , I can pass that guy on the racing bike . And probably stay in front of him , too . Hello , DenverNo but really , why do I keep biking ? Do I even enjoy it ? It seems like other people who enjoy biking enjoy it rather more . Was that gnarly pothole at the bottom of this hill or the next ? Smells like pond . I guess I enjoy it . I certainly enjoy the metabolism .
