I actually got a nice surprise about being a mother because I expected it to be harder and to have to make more adaptations.

Doing the long endurance stuff seems to have given me the strength to sustain the speed. I think my body is just a lot stronger (thanks to the marathon)... By increasing the long runs, I found that does not take anything away from the speed but increases the strength on the track.

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 set myself some specific goals, but the key one is just getting myself into as good a shape as possible for one day this year: the Olympic marathon.

Every time I go out and race it's a goal to go out and run faster than I've done before.

To represent your country at a home Olympics is something special and I'm over the moon to be selected for Team GB. I was pleased to get the qualifying time in Berlin earlier this year and my sole focus is getting in the right shape for London.

You can't magic yourself back 10 years.
