That is not enough. Sport has been great for me, a great learning place that if you want to achieve you can, even if you are from the poorest part of Africa.

You must do as your people do. If my people are poor, I must be poor. People ask me, 'Why don't you find a personal coach or a private car?' I can't. Then I won't be part of my people.

If I don't train enough, of course I'm nervous.

My father thought sport was something fun - he didn't know it was a way to make money. Then I won a Mercedes at the world championships and I gave it to him. From the moment it arrived my father said: 'Good, you can support not just yourself but me too'.

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.

The marathon always starts after 30K. That's where the problems start. You start without any problems, without any pain. All the pain comes after 30K. Sometimes, it's possible to have pain even in the finger.
