I don't have a bicycling personal website - but I do post about bicycling on my personal website (in its own category, so it can be seperated from therest of the content if you want).
I'm not much for personal content as I just don't care to share things with the world like some sort of neurotic attention-wh*re - but I did start journaling about biking the day I bought my Kona (this past week, in fact).
I'm a big obese guy (over 500lb), so as embarassing as it is to be that revealing and open on my site, I decided it was necessary to keep myself motivated. If there's ever a day where I feel like slacking off on any aspect of biking or health, I'll know that I have to get my stuff together because I don't want to look weak to the rest of the world.
Anyway, it's
