Sometimes when you get disappointment it makes you stronger.

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

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

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.

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.

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.
