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.

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'm a runner first before anything else.

I was the kind of child who worked hard every day with the cows and sheep - I was a very aggressive boy.

I always tell young athletes the same thing, 'Wherever you go, whatever you do, what must your top priority be? Running.'

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.
