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.
I always tell young athletes the same thing, 'Wherever you go, whatever you do, what must your top priority be? Running.'
Many people know that Ethiopia is poor. When I break a world record, maybe people get to know something else about Ethiopia, something good. We can't make planes or cars, we don't have the materials. We do what we can.
When we race in London a world record will be the last thing on our minds.
I think if you come first with a new world record, that is the best.
My father didn't think running was sensible. He told me running is just wasting time.
