Not only is [a half marathon] a good test for the marathon, it is also good for those who feel they were just getting going in a 10K and are physically and mentally primed to go further. A half marathon is a good test of your endurance, without the physical punishment of going the full 26.2 miles. More so even than the 10K, it will teach you about patience, pacing, and how to negotiate a wider range of physical and emotional cycles.

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.

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.

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.

I am about to get involved with the biggest cancer hospital in Norway. They are building a fitness center to work with patients. I will be a consultant.

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.

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