I never let anything stop me from doing what I want to do.

But I'm after medals more than anything. Championships don't get taken away from you but records do, so I think I'd rather have medals at every championships rather than times. A world record would be a bonus, but I'm still only 25 in 17 days.

When it becomes hard for me not to eat bad food, I try to think about what I have to do and what is ahead of me and what I want to achieve.

I know who my dad is, I've met him a few times, but I don't even call him dad. I know it sounds horrible, but I don't even see him as part of my family, to be honest. If you want the truth, it doesn't bother me because I don't know any different. I just know that me and my mum, that was my family.

Coming over to Europe you can always put on weight really easily because you are not doing your normal routine at home. It is just a bit more discipline and not eating breads and pastas which are my favourite foods in the entire world.

Not a lot of people know me outside of athletics and believe it or not I am actually quite shy. The exhilaration of a win or tears after falling are the extremes. It takes me a while to get to know someone, but once I do I am very loyal to my old friends.

My goals were last year to win the world champs and this year to win the Olympic Games and I've done that and I couldn't be happier.
