When you promise something, you must fulfill it.

Athletics is in my blood.

When I had no shoes I was comfortable - I used to run barefoot. When I wore shoes it was difficult. To run in shoes was ok, but at the beginning of my career it was hard.

I know what I want when I start a marathon: to win! But what do you want? Make sure you're clear in advance and don't go out too fast.

He was not a runner, my father, but he was quick. I always remember it was very difficult to escape from him when he was angry. If he wanted to beat us he would always catch us. Even me, he could always catch me.

Always, if you win mentally, you can win physically as well.

Like some high official, you have to tell your brain: 'Do it. Come on. I have to do it.'
