It's been 2 weeks since I started riding my bike to work (and home again). I'm feeling much better, cooling off faster after each rode, and gradually getting faster.
I've missed 3 rides (took one day off to hit the mountains, and had a family shindig one evening), but other than that, I've been riding full time. I don't see anything that would make me stop now, except for wet (or white) stuff.
To keep myself motivated, I've been keeping a "ride log" here using Drupal's custom content types, and some custom PHP/MySQL to generate an overview. That's worked out pretty well from a technical perspective, and helps me to see at a glance how I'm doing.
Now, to put some cash into my bike. Hand grips are cracked and falling off. Gears need adjustment. Some mystery squeek/creak from the frame when I pedal. I'll need a headlight/taillight soon, as it starts getting darker in the mornings. I really should put a bell on it, especially now that there's at least a microscopic chance that I might actually pass someone...
