I will always listen to my coaches. But first I listen to my body. If what they tell me suits my body, great. If my body doesn't feel good with what they say, then always my body comes first.

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 want to go down in history.

I'm lucky. The best possible place in the world for training is Addis Ababa, so I am home all the time except when I am racing. I like to be there, near my family, my kids, also the real estate business I run with my wife.

What can you do if a part of it is uphill? You can't work out another route. You've just got to run the one they give you. But they tell me London is a nice course. Even the cobbles, I hope, are not very much of a problem for me.
