I had as many doubts as anyone else. Standing on the starting line, we're all cowards.

Whatever we accomplish in life, if it's solely for our own good, then it doesn't mean that much. The things you do that affect others in a positive way are the ones that count. Whatever facet of life you're in, God has given you a gift; do the best you can with that gift.

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

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 think in running, to be honest, that even though athletes are very dedicated and are willing to train and do whatever they need to do to prepare, more often than not they're not in a very professional environment where you've got a high performance director and a coach that are really monitoring your daily activities.

I run four miles most days, at about 8:00 to 8:15 pace. It's totally relaxed.

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.
