I wasn't the kind of kid who would get A's without even trying. I had to work to get good grades, but I was very organised about it because I always wanted to do well at everything I did. I'm very competitive.

Things have changed so much, with Facebook and Twitter. Everyone is so much more accessible these days: no British athlete has ever experienced what we are experiencing now. It's such a unique situation with the home Olympics.

I don't look at Twitter between events because it's a distraction but I will ring my fiance and parents to let them know how it's going.

We always spend more time on the throwing events and a little bit more on the long jump. They're my weaker events - they don't come as naturally to me as running and jumping. I like the hurdles and the high-jump, I'm a springy, speedy athlete so those suit me.

I carry a golf ball to put under my feet when they get tight, and a Thera-Band for general stretching.

Training is full-on. Some days I really don't want to get out of bed and hit that track again. Sunday and Monday morning sessions are always horrible. But who really looks forward to going to work on a Monday morning?
