Right now, after having had back surgery, I am finally back to running again.

How did I know you ran a 4:30 mile in high school? That's easy. Everyone ran a 4:30 mile in high school.

When you first run up First Avenue in New York, if you don't get goose bumps, theres something wrong with you.

Hills are speedwork in disguise.

The irony of that is, what makes it kind of ironic, is when you do become successful as a professional athlete in particular, a lot of the young children who are emulating these stars do have a different perspective.

You can actually suffer a little bit more going slowly than when you're going really fast. A faster marathon might even be easier than a slow one, in terms of what it takes out of you mentally.

You have to know your body. It's part of the beauty of the training process, and once you've determined how much your body and mind can take, you can then begin to reach your potential.
