As a kid, I wasn’t very intentionally athletic; I didn’t take part in sports leagues (mostly because I lived in the middle of nowhere) and my interest in school athletics died out after middle school when it got competitive. In high school, I fulfilled my PE credits with marching band.
Despite my lack of interest in physical fitness, when I was 16 or 17 I started jogging, and I’ve been at it since pretty regularly since. The other day, I decided to total up the number of miles I’ve probably run in my life. I’m currently running 12-20 miles per week, but there were periods–especially when the kids were young and we lived in a colder climate–where I ran a lot less. So, I figure 10 miles per week or 500 miles per year is a safe average. At that rate, I’ve run around 16,500 miles in 33 years. Again, let’s round that down to a nice 15K miles for good measure. I find that amazing!
