In my Olympic history I don't think I have achieved my potential as an athlete. That's what I want when I look back at my career. I want to be able to say I gave it my best shot.

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.

You can be strong and true to yourself without being rude or loud.

It's totally different from last year because I came in with good shape with no health worries so it was about going out there and running well and enjoying it.

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.

I took a lot of bad things after Athens. I just learnt to deal with it. The problem was beforehand I had this feeling where I was trying to please everybody - I wanted everybody to like me.

I start planning then that's dangerous because then I have a target that I'm blinkered towards and I won't listen to the warning signs quite so much. I'd rather be in shape and then look around and say there's a race next week and jump into that than have it planned.
