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.

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 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 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 love my tribe, the Maasai are very good people and humble.

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.
