Twas a lovely day for a run.
You know you're a runner when your ties last a lifetime but your running shoes last 6 months. You know you're a runner when no amount of weight lifting can satisfy you quite like being out on the trails. You know you're a runner when you finish races at the back of the pack and you could care less. You know you're a runner when it has become increasingly more difficult to tell yourself that you're not a runner.
I am a runner.
