The marathon is like a bullfight.

I'm doing great heart-wise. I get a complete stress test once a year, and those have gone well. I have stents in two arteries, and they are holding up. My other arteries haven't shown any additional clogging.

You have to change things in order to get to where you want to go. And things might get worse. But if you're not getting where you want to be, already, in a sense, it's as bad as it can get.

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

I like the marathon because it's one race where you can find out who's really the toughest. On the track, sometimes a guy can just pull away, and you want to stay with him but you don't have the leg speed. The marathon is slow enough that anyone can stay with you if he wants, if he has the will. The marathon is ultimately a test of will.

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.
