There is something about the ritual of the race - putting on the number, lining up, being timed - that brings out the best in us.

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.

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

You've got to look for tough competition. You've got to want to beat the best.

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.

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.

Another inspiration that has helped me get through has been Lance Armstrong's story. My cancer is not nearly as bad as his, but I believe in staying motivated and keeping as fit as you can.
