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.

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

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.

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.

You can't become a winner overnight, or even in a couple of years-it takes time... You will lose races and you will have to accept that, learn from it and believe that you'll win the next one, knowing that you'll probably lose that as well. All the time you have to keep believing that one day you will win.

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.
