I know what I want when I start a marathon: to win! But what do you want? Make sure you're clear in advance and don't go out too fast.

When you run the marathon, you run against the distance, not against the other runners and not against the time.

You need three things to win: discipline, hard work and, before everything maybe, commitment. No one will make it without those three. Sport teaches you that.

I used to run to school, 10k every day. And this at altitude, perfect preparation, really.

I have seen things few of my countrymen have. The first time I went on an aeroplane I couldn't work out how the lavatories worked up in the sky.

This hand is not very active always, because it was in this hand that I carried my books. My carrying hand was always my strongest. Now I think my other hand has developed more muscles from signing all those autographs.

Like some high official, you have to tell your brain: 'Do it. Come on. I have to do it.'
