I have not had the chance to go out there and do myself justice in an Olympic marathon yet. I have not been able to get to an Olympic marathon injury-free yet.

I apologise to people when I need to.

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

Never set limits, go after your dreams, don't be afraid to push the boundaries. And laugh a lot - it's good for you!

I've been to three Olympics and I don't feel I've ever quite achieved my best at any of them.

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

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.
