When I was a little boy, I always wanted to run. I loved competing with my friends.

Races always are good to show where you are reaching in your training as well as to keep you sharpened. Every race, in my program, I put it in a special way like a ladder, climbing up slowly and slowly to the next one. I see where my training is, and that is like a test.

The Olympics is a special event and winning is very important. For me as a world record holder and world champion, the only thing I am missing is the Olympic gold medal and that is what I want to achieve in my career.

The weather plays a very big role. I have run very few races in the raining and the cold.

Already in 2007 I thought I would be able to break the World record in the near future. That time Sammy Tangui was the pacemaker in Lausanne. I liked the way he was running. He is tall, he has a strong body and his stride is similar to mine. I told him in one of the coming years I would need him when I try to break the World record.

Even if the pace is slow in championships, you can still sprint well and still power in the last 200, which is always the main part when the race is slow.

It's something special to break the world record at the Olympics.
