That's what running does to lives. It's not just exercise. It's not just achievement. It's a daily discipline that has nothing to do with speed, weight, social status, sexual orientation, political affiliation, where you live, what car you drive, or whether anyone anywhere loves you. It's about the slow and painful process of being the best you can be.

I don't know if there's a proper way to define toughness in a runner, but I do know that there comes a sudden moment when the mindset shifts. The impossible becomes doable, or at least attemptable. The long run goes from two miles to four to ten to fifteen, until it becomes routine at some point deep in an intense training cycle to knock off a couple hours without giving it a thought.

Running has taken me on adventures great and small, at home and around the world. It has provided me with hope and perseverance on days when I had none-and even, once every great while, warmed me with that fleeting ray of sunshine known as glory. Running has taught me that I can do anything, just so long as I keep putting one foot in front of the other. Sometimes that notion is metaphorical and sometimes not. In this way, I have been inspired to attempt things I would have never dreamed possible. And it all started with a single step.

To be a runner is to learn continual life lessons. To be a coach is not just to teach these lessons but also to feel them in the core of your marrow. The very act of surpassing personal limits in training and racing will bend the mind and body toward a higher purpose for the rest of my runners' lives. Settling for mediocrity-settling instead of pushing-those who learn to be the best version of themselves know the secret to a full life.
