The greatest stimulator of my running career was fear.

I hadn't a clue who I was racing against. All I knew was how I was going to race.

Training was a time where resolutions made in the enthusiasm of an inspired moment were put to personal test.

The single biggest change in middle-distance running, from the 1500 metres to 10,000 metres, has been the track surface.

The important thing is the attitude of the athlete, the desire to get to the top.

Poetry, music, forests, oceans, solitude-they were what developed enormous spiritual strength. I came to realize that spirit, as much or more than physical conditioning, had to be stored up before a race.

I have never been a killer. I'm not an aggressive personality and if I can remember any emotion I felt during a race it was fear. The greatest stimulator of my running was fear.
