You know for me when I promise something I want to deliver. If you don't, you have to disappear.

I remember in particular my first victory when I achieved a very fast time in what were perfect conditions but since then the wind has always been a factor against me.

Like some high official, you have to tell your brain: 'Do it. Come on. I have to do it.'

I'm a runner first before anything else.

My father thought sport was something fun - he didn't know it was a way to make money.

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 haven't done a marathon for a long time. So we'll see. I will need good luck.
