I've had a lot of success over the years racing in New York, but the main point is that I feel the marathon is a different event, a lot more my event.

In the week before a race, I try to stay away from germ areas. I keep disinfectant wipes in my bag for when I have to use a supermarket trolley or something like that.

The biggest danger is trying to put too much pressure on yourself, trying to get in too good shape.

There's always going to be somebody who takes a dislike to you and you can't waste time worrying about it.

I have achieved a lot and I'm grateful for that - I'm just a bit greedy because I want to add the Olympics. It's once every four years - everyone wants it and very few people get it.

At big championships it's not the fastest person, it's the person who gets it right on the day.

I don't feel guilty in having pleasure!
