This is what I wanted. They tell me that London is the best field in history. I wanted to be part of that. Because everyone will be there it will be a wonderful challenge for me. You can see the best runners, how they look, how they run. For me to beat the best is what counts.

In the rainy season, sometimes to get to the first lesson we had to run really quick, because we had to cross the river to school and we'd have to go up and down the bank to find a place to cross because there is no bridge.

When I wake up at 5 in the morning is it just to jog? Definitely not, I give it all of my efforts.

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.

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

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.
