The worst injury I ever had was a stress fracture from running.

I am a private person and that has always been my personality.

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

I don't think I would have been such a good runner if I hadn't enjoyed it.

For every finish-line tape a runner breaks -- complete with the cheers of the crowd and the clicking of hundreds of cameras -- there are the hours of hard and often lonely work that rarely gets talked about.

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.

Sustained motivation is essential to achieving your potential.
