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

I'm a runner first before anything else.

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.

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.

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.

When you talk about world record times, you have to understand that everything must be perfect the weather, the course, the temperature. It is not always enough to be in good shape.

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