About two years ago, I weighed in at 225 @ 6'3''. I got a DUI and assault charge for running over a crackhead who ran across 4 lanes of traffic in the dark. Needless to say, I lost my license. From January through May (in suburban Denver) I had to use my bike or walk everywhere. I went from 225 down to 173. Some of this was probably due to stress though. I was looking at some prison time but my lawyer got me a good deal :-). I Have since gotten my car back and have returned to my rightful weight of 225. 173 was nice though :-)
However, being a Clydesdale is not so bad. I may be big, but I haven't found a riding buddy to keep up with me, especially on the climb! If you're local and you have the same issue, maybe you should PM me. I road single track and road but prefer the dirt these days.
My bikes: 2004 Specialized Allez Pro, 2014 Trek Remedy 8, 1987 Miyata
