Every day I spend time on the treadmill. I am walking faster, stronger and harder than I was two months ago.

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.

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.

I tried to keep it secret, but the story got into the newspapers. It was more difficult for my family, who couldn't understand why the media wouldn't leave me in peace.

Sustained motivation is essential to achieving your potential.

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