I've been reading these forums for a number of weeks now, and would like to thank everyone that contributes here -- there is such a wealth of information!
In early September, my doctor told me I had to lose 50 pounds to avoid exacerbating a disease I have called Ankylosing Spondylitis. I started by just dieting, but felt I really needed to add an exercise component. I cannot stand dealing with gyms, so I went looking for an alternative. I considered commuting on my bike. I thought I would give it a go event though it was a "pretty long" commute at 7 miles one way (I know, I know -- this is a laughable thought process after learning the commute lengths of some of the commuting forum posters). I'm very lucky in that 85% of the commute is on a dedicated bike path from San Jose to Los Gatos.
After visiting a few of the LBS's, I decided on a Giant FCR2. I've been commuting 3-4 days of the week for about three weeks now. My legs are constantly sore, but I'm sure this will pass. I'm looking forward to learning how to maintain my bike myself. I bought Zinn and the Art of Road Bike Maintenance to this end.
As for the weight, I've lost 13 pounds so far, and am down to 206. My goal is to get to 170 by the end of Feb. I have no doubt that commuting via bike will help me get there. And who knows... maybe I'll get the fever to do more than commute after a while
