I just want to be in the best shape I can be. Not to stand on that start line and say: 'Oh my God, I have this injury and that injury.' I just want to be able to go out and race.

Actually I don't choose to expose myself in public. I choose to compete; the other side just comes with the package.

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

It's important that athletes can compete on a level playing field. And youngsters coming into the sport can know that if they are working hard and training hard, they'll see a true reflection of where they stand and what they can achieve worldwide and not be swayed by people who are cheating.

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.

An Olympic medal won't define my whole life, although it might look like it to onlookers. When I look back, I should have been able to get an Olympic medal.

I am not going to let Athens affect the rest of my life.
