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.

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

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

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.

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.

Sometimes when you get disappointment it makes you stronger.

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