I think your body is just a little bit stronger after pregnancy.

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

We, as athletes, have our suspicions about who's cheating, but I'm not convinced that the testing has yet caught up with what people are using or what they are using to disguise 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 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.

I'm confident of what I have to achieve in the buildup to London 2012.
