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.

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 can't imagine living and not running.

Plenty of people who are 38 have run really well in the marathon.

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

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