Many people know that Ethiopia is poor. When I break a world record, maybe people get to know something else about Ethiopia, something good. We can't make planes or cars, we don't have the materials. We do what we can.

When I run in Ethiopia, I look out and see eucalyptus trees and rivers.

I remember in particular my first victory when I achieved a very fast time in what were perfect conditions but since then the wind has always been a factor against me.

My school was six miles away from where I lived on the farm. I had to walk and run, there and back every day, through gorges and over rivers. If I was late, there was a very big stick waiting for me.

My father thought sport was something fun - he didn't know it was a way to make money. Then I won a Mercedes at the world championships and I gave it to him. From the moment it arrived my father said: 'Good, you can support not just yourself but me too'.

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 know for me when I promise something I want to deliver. If you don't, you have to disappear.
