It's really important for me to look good before a race. I definitely think if I feel I look good, it makes me feel more confident.

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.

To get the adrenaline pumping between events - or to help me switch off, Jay Z, the Roots and Drake are on my playlist.

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?

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.

After my first day of competition I put on compression socks. They help me recover for the next day.

People think the gold medal is yours and they say you're going to win - but they have no idea how hard it is. People aren't doing it negatively - they're mostly lovely and they really do want you to win - but they don't understand the difficulty and intensity of competition.
