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

When you promise something, you must fulfill it.

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

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.

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 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 think if you come first with a new world record, that is the best.
