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

I don't think I would have been such a good runner if I hadn't enjoyed it.

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.

What spurs a person to get more serious is highly individual, but I have found that no matter what a person's level of ability, motivation must come from within, or it will not last.

Sustained motivation is essential to achieving your potential.

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.

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.
