I'm retiring from competitive running, not from running. You cannot stop running, this is my life.

My father didn't think running was sensible. He told me running is just wasting time.

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

In the marathon a crazy athlete can just keep pushing from the beginning, at a championship you don't need a time just to win the race.

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.

I have to change a lot of things before I become a good marathon runner.

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