I'm really hard on myself as well, nothing is good enough for me in training. I always want more, I always want to give 100%. I use my training like a competition. I imagine these two girls next to me every time single time I'm going over those hurdles in training.

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 imagine these two girls next to me every time single time I'm going over those hurdles in training.

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.

It's always, 'Are you the runner girl?' I say, 'My name is Sally actually.' I used to always get that at school as well, 'Are you the runner girl?' I'm not even the runner girl, I'm a hurdler.

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.

If you hold back in hurdles, you are going to fall over.
