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.

Once you have commitment, you need the discipline and hard work to get you there.

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.

When I had no shoes I was comfortable - I used to run barefoot. When I wore shoes it was difficult. To run in shoes was ok, but at the beginning of my career it was hard.

I can't change everything by myself but I can be one of the people who are trying to change the situation.

I wanted to experience New York, to look up and see buildings.
