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.

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

My family means everything to me and the birth of our daughter has enabled me to have more focus on my career and every time I compete, I dedicate my success to them.

My father's encouragement is what has brought me this far, because when I grew up I wanted to be like him, and I knew I had that ability to become an athlete. Being an Olympian is one of the greatest things, and being an Olympic gold medallist is one of the most prestigious titles in the world.

I missed the final of the World Championships in 2009, but I told the coach I would break the world record in 2010. Which I did. Then in 2011 I won the World Championships and now in 2012 it is the Olympics. That is how I have been working.

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.

Fantastic, I am very happy to be the fastest 800 metres runner in the world.
