That is not enough. Sport has been great for me, a great learning place that if you want to achieve you can, even if you are from the poorest part of Africa.

Age for me is just a number.

In my life I do a lot of things but I never forget my training.

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

You need three things to win: discipline, hard work and, before everything maybe, commitment. No one will make it without those three. Sport teaches you that.

This is what I wanted. They tell me that London is the best field in history. I wanted to be part of that. Because everyone will be there it will be a wonderful challenge for me. You can see the best runners, how they look, how they run. For me to beat the best is what counts.

If your body is damaged, wounded, it can be fixed, but if inside, mentally, you are wounded you cannot fix it, it's hard.
