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.

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

Even today, in retirement, I find it very distracting if there is conversation during a run. I work out as much for my head as I do for my body. I'm a thinker. A lot of my ideas come to me more easily when I am running. That is why I like to run in the morning.

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.

To suddenly be a hero on a world basis was hard for me to understand. God gave me a gift. I got the chance to use it. I didn't think I deserved what people were saying. My talent is just more visible than theirs.

Running gives me a clearer perspective on the world, and it makes me feel special. I've never been a traditional tourist. I've always seen the world by running, and that has allowed me to view things in a different way. Places look different in the early-morning hours, when the streets are deserted.
