The type of IBS I am prone to is the constipation type, where I get trapped wind and can get sharp painful spasms in my intestines as well as having sluggish bowels.

Me and my brother just used to fight all the time; then my sister came along, and it was all about the little girl in the house. We'd always eat dinner together as a family.

I'm a very keen baker; I pride myself on my cakes. I go along the classic sponge line, but I like to jazz it up: I've made some psychedelic birthday cakes.

Jumping isn't as important to my training as you might think; I'm only in the sandpit once a week. There's a high risk factor of injury doing it, so instead, I rely on my progress in the gym to judge how far I'll jump on the big day.

Running up a steep hill or up steps are fantastic ways of building explosive strength.

I take magnesium to prevent cramps. A few years back, I suffered from hamstring tears, and part of that can be to do with muscle cramping, and then pushing the muscle at that point. I also take a fish oil supplement.

I drive relatively fast - within the remits of the law, obviously - but I struggle with people who do stupid things on the road. I have a massive urge to shout expletives at them.

I come into these competitions to win, not to get silver or bronze, so it is frustrating.

Athletics set the right sentiment for a clean and believable sport.

People forget that track and field is one of the hardest sports because we compete against all the world. There are many sports when you are up against only 15 or 20 countries.
