This is so true. I think its part of what's great about being a 'runner.' It's not like being a trobone player, where you have to be pretty good to tell people you are one. If you go running today, you are a runner.
Even if you’d never get old or even get fat and your dog could take itself out and everyone loved you and you always slept well and you never got sad and all your teachers all thought you were a genius and no one ever broke up with you and every scholarship was a full scholarship and the world wasn’t a mess and your body looked good all on its own and every day in every way you felt like you wanted to feel, you’d still run.
I suffered from horrible shin splints when I played soccer, attributed to all of the running I did(I was a midfield and forward and played lacrosse and ran cross country, in addition) Now I have pretty bad plantar fasciitis, yikes. Great guide to running.
