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.

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.

My father thought sport was something fun - he didn't know it was a way to make money.

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.

What can you do if a part of it is uphill? You can't work out another route. You've just got to run the one they give you. But they tell me London is a nice course. Even the cobbles, I hope, are not very much of a problem for me.

You know, I want to help my country. Definitely I can help them, simply by winning races. Sure, they can follow my path to a good career. But for me it is not enough. I want to be more than that. In everything I want to be a role model.

My father didn't think running was sensible. He told me running is just wasting time.
