All through high school and college I absolutely lived and breated for the sport of running. School, work, and even my social life were like things I did on the side. Then at 21 I suffered the first of an extremely frustrating string of injuries that spanned the most dressed time in my life
I was finally able to get back into it on a serious basis at 24, but during my time off I was basically forced to learn to appreciate other things. Now at 26 I'm getting as much enjoyment out of running as ever (although I do feel like kind of a chump when some 17 year old hotshot nips on my heels). However, I mave a much richer life outside of running than I ever did before, or would ever have had if if not for the injuries.
It's just amazing, in retrospect, how consumed I was by it. I thought it was a truly healthy obsession, but I could have gotten lost in running for the rest of my life.
