I am quite impressed with the progress Ryan has made, and have always hoped he would make it, but doubted he would. He did (as I recall) start out earlier than he initially expected, so some of the forums skepticism was probably helpful...
My doubt is shrinking.
I believe I read somewhere in the past week poking through Ryan's site and background, that he played college football, so I think even though the muscular demands are different, the discipline of college football is paying off for Ryan and part of what is making this work for a relatively inexperienced cyclist.
Ride Ryan, Ride!!!
