I'm interested in Dathan Ritzenhein's future in the marathon, and I believe that's where we need to address some issues he seems to have. He's had good marathon coaches - both Brad Hudson and me. He's figured out the fueling. He's got this incredible aerobic engine. But something's still wrong.

I can't tell you why a particular athlete would leave a certain coach, but I can tell you there could be many reasons. They could have personality conflicts. They could have misunderstandings. Lots of stuff can happen.

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.

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

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.

I've found that my athletes run their best races after about 10 weeks of intense training.

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