I've never enjoyed my running more. I also do 200 sit-ups a day, 60 push-ups, and a lot of stretching. I've had some back issues. I think the stretching helps with that.

I didn't give myself enough breaks during the training year to recover. I didn't understand the power of periodization.

We may train or peak for a certain race, but running is a lifetime sport.

Trust me, my runners aren't going to run one event while looking past it to the second event. When they get on the line for the 10K, that's a do-or-die situation for them.

Winning times in the New York City Marathon have not dropped all that much over the years, but rather U.S. runners went backward. In 1983, there were 267 U.S. men who broke 2:20 in a marathon, and by 2000 that number was down to 27.

If you want to achieve a high goal, you're going to have to take some chances.

With my runners now, they get two month-long breaks during the year.
