I didn't ride yesterday; too busy eating and partying and watching football, but in 2008 overall I did manage 206 rides for a total of 7,577 miles.  That's an average of 37 miles per ride, and 146 miles per week.  Yay, me.

Looked at another way, that's about ten hours of riding per week, which is about 7,000 calories, or about 1,000 calories per day...

I'm pretty sure I could never get that much exercise any other way.  I had to find something I liked to do - anyway - and in so doing trick myself into getting a workout.  Cycling is not for everyone, some people like to run, or swim, or whatever...  one thing for sure, it beats walking to the 'fridge :)
