Our bodies crave exercise, and reward us in so many ways when we do so.
We are designed to run and we increase our chance of daily happiness when we do so.
If you're laboring up a steep hill, imagine that a towrope is attached to the center of your chest, pulling you steadily toward the top.
Here is the start, there is the finish line. Between that, you have to run.
We have a no puke rule. The purpose is performance, not puking.
Being an athlete is a state of mind which is not bound by age, performance or place in the running pack.
