I took a lot of bad things after Athens. I just learnt to deal with it. The problem was beforehand I had this feeling where I was trying to please everybody - I wanted everybody to like me.

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

You can't magic yourself back 10 years.

I have always run as hard as I can. You are not going to run any harder with or without men. You are running on your own two feet.

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.

You can wish as hard as you like but all that really matters is the shape you're in on the day of the race. I've always felt these really big races aren't necessarily won by whoever is the fastest. They're won by the athlete who is the smartest and in the best shape on the day.

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.
