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.
