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.

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.

I love running. It's as simple as that ... it has given me endless rewards: physical, emotional, and professional. The benefits of running are lifelong. I ran as a child, and I intend to run into my old age.

Spend at least some of your training time, and other parts of your day, concentrating on what you are doing in training and visualizing your success.

Exercise and sports are greatly affected by what goes into the mind, and the mind is greatly affected by sports and exercise as well. This is true among exercisers at all levels, despite their different goals. A major element in mental training is visualization ... Visualizing a positive outcome can create a pattern of success, as long as you set realistic and specific goals.

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.

If you are training properly, you should progress steadily. This doesn't necessarily mean a personal best every time you race ... Each training session should be like putting money in the bank. If your training works, you continue to deposit into your 'strength' account ... Too much training has the opposite effect. Rather than build, it tears down. Your body will tell when you have begun to tip the balance. Just be sure to listen to it.
