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.

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

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.

Going to the Olympics as a Maasai I want to make them proud because, after the warm welcome they gave me when I went back and being their leader, I want to also be the warrior in the Olympics. That will be something good because that will be the first Olympic gold medal for the Maasai.

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

Races always are good to show where you are reaching in your training as well as to keep you sharpened. Every race, in my program, I put it in a special way like a ladder, climbing up slowly and slowly to the next one. I see where my training is, and that is like a test.

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.
