I used to run to school, 10k every day. And this at altitude, perfect preparation, really.

I was the kind of child who worked hard every day with the cows and sheep - I was a very aggressive boy.

When I was 17, I used to really think about what I wore every day.

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.

In the rainy season, sometimes to get to the first lesson we had to run really quick, because we had to cross the river to school and we'd have to go up and down the bank to find a place to cross because there is no bridge.

I run every day now. I never ran before.
