I realized I could run after finding out that my dad used to run and it gave me the morale that if he did it then maybe I could also run.

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 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.

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.

Sometimes when you get disappointment it makes you stronger.
