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.

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.

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 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.
