Never set limits, go after your dreams, don't be afraid to push the boundaries. And laugh a lot - it's good for you!Collection: Dreams
You see, with me, when I'm nervous, I smile and laugh.Collection: Smile
For an athlete, the biggest pressure comes from within. You know what you want to do and what you're capable of.
I deliberately returned slowly to training after Raphael was born and everything, apart from being bitten by a dog whilst out training in Monaco at the beginning of the year, has gone pretty well.
A half marathon is a good way to have a bit of fun and race against those girls and learn a bit more about them. The world half marathon is a world championship at the end of the day and it's important. I've win it twice and it's a quality event.
It's totally different from last year because I came in with good shape with no health worries so it was about going out there and running well and enjoying it.
I am not driven by any bitterness by what happened in Athens. I learnt a lot of lessons from it and probably came through it a stronger person in the end. There have been a lot of near misses, and that's taught me to keep persevering and that there is a chance it can come right.
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 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 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 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.
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.
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.
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 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.
I have not had the chance to go out there and do myself justice in an Olympic marathon yet. I have not been able to get to an Olympic marathon injury-free yet.
If I start planning then that's dangerous because then I have a target that I'm blinkered towards and I won't listen to the warning signs quite so much. I'd rather be in shape and then look around and say there's a race next week and jump into that than have it planned.
I actually got a nice surprise about being a mother because I expected it to be harder and to have to make more adaptations.
I've always been good at putting things behind me - I fall apart, do my crying bit and then put it away and move it.
If you look back at my marathons and ask whether I would swap one of them for my one balls-up, of course I would. But you can't choose. You have to make the best of it on the day.
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've had a lot of success over the years racing in New York, but the main point is that I feel the marathon is a different event, a lot more my event.
I have always loved running on the roads, ever since I used to take part in relays for my club when I was 12 and 13. I felt really at home on the surface.
Actually I don't choose to expose myself in public. I choose to compete; the other side just comes with the package.
Yeah, ideally, I'd probably wish to be more anonymous. But scrutiny and success go together. And I want to be successful.
I have achieved a lot and I'm grateful for that - I'm just a bit greedy because I want to add the Olympics. It's once every four years - everyone wants it and very few people get it.
