In terms of fitness and battling through cancer, exercise helps you stay strong physically and mentally.

One day you are happy and laughing and the next you are crying.

For a couple of days after chemotherapy, food tastes really bland, even the best foods. I haven't been sick, but have been a little tired. I haven't lost any weight.

Too many people I meet believe that you can sit in a chair and be given motivation. With exercise and fitness, you get it by doing. The mental qualities you need are all linked like a chain. If you give exercise a try and see results, even if it's as simple as feeling good that you get out the door, you'll become motivated to repeat the exercise. Seeing results is inspiring.

Everyone wins the marathon. We all have the same feeling at the start-nervous, anxious, excited. It is a broader, richer, and even with twenty-seven thousand people-more intimate experience than I found when racing in track. New York is the marathon that all the biggest stars want to win, but has also been the stage for an array of human stories more vast than any other sporting event.
