When I decided that the weather (was right), I had to take the chance. The real thought in my mind — and by then I did have a coach, Franz Stampfl, we met by chance in the train — I hadn’t planned to do it. He said, “If the weather is bad, what you have to remember is that (a), I think you can run it in 3:56,” which is what a coach would say, so I didn’t pay too much attention to that. The second thing he said is that if you have an opportunity, not a perfect opportunity, and you don’t take it, you may never have another chance. It was that thought, I think, which eventually led me to attempt it.
