You know for me when I promise something I want to deliver. If you don't, you have to disappear.

My father thought sport was something fun - he didn't know it was a way to make money. Then I won a Mercedes at the world championships and I gave it to him. From the moment it arrived my father said: 'Good, you can support not just yourself but me too'.

If you're planning only to make money and nothing else, you'll be broke.

When you run the marathon, you run against the distance, not against the other runners and not against the time.

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.

At the moment I am a little bit politician, yes. I think that could be my next step. It is not because I want power, it is because of what I think I could do for the people.

Some people start a sport just to reduce weight, or some say, 'My doctor ordered me to run and do exercise', and for others, they run for completely different benefits. But it is not like that with sport. We need to eat, we need to rest, but also we need to run.
