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

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'll never do that again!

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.

My basic philosophy can be summed up by an expression we use in Norwegian: hurry slowly. Get there, but be patient.

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.

The worst injury I ever had was a stress fracture from running.
