When you talk about world record times, you have to understand that everything must be perfect the weather, the course, the temperature. It is not always enough to be in good shape.

Since I achieved something, running has exploded in my country.

My school was six miles away from where I lived on the farm. I had to walk and run, there and back every day, through gorges and over rivers. If I was late, there was a very big stick waiting for me.

I'm a runner first before anything else.

Once you have commitment, you need the discipline and hard work to get you there.

First, do enough training. Then believe in yourself and say: I can do it. Tomorrow is my day. And then say: the person in front of me, he is just a human being as well; he has two legs, I have two legs, that is all. That is mentally how you prepare.

If I don't train enough, of course I'm nervous.
