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.

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

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.

I was ready in 2008 for the Olympic Games but unfortunately I missed the Kenyan trials with a thigh injury. I watched those Olympics but it was tough to watch. But it was good in the end because a Kenyan, Wilfred Bungei, was the champion.

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

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

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.

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.

Going to the Olympics as a Maasai I want to make them proud because, after the warm welcome they gave me when I went back and being their leader, I want to also be the warrior in the Olympics. That will be something good because that will be the first Olympic gold medal for the Maasai.

I was still young when I missed Beijing. I was favourite to win a medal but I knew I had time. My coach advised me to stay at school and finish my exams. Even if I had gone and won the Olympics, I might not have handled the pressure. So I moved on.

Sometimes when you get disappointment it makes you stronger.
