I want to jump far all the time and go out there and win medals.

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.

Even though arguably I could have done much better at school, I'd decided at a young age that I was going to be a professional sportsman at some sport. And at that stage, there was a bit of luck: I was fortunate to meet the right people at the right time to get me to where I am now.

I'm a bit of a history goon, and I love all that. Anything that's medieval-based up until, probably, the Tudor period and just after, I'm quite into.

The DNA showed I have a level of endurance in me which I never really realised, which makes sense.

I do a lot of things like running hills and larger amounts of reps in the gym.

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.

Fruit is carb-based, and I limit carbs when training hard.

I eat a lot of vegetables and salad. I put strawberries, pomegranate seeds, blackberries, and blueberries into shakes and add Greek yoghurt for a snack. I have this when I'm not training.

When at home in Buckinghamshire, I tend to work out for two to three hours on the track or in the woods close by and then do weights.

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

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.

I train six days a week.

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.

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.

For a long time, I thought I'd be a physio if I wasn't a sportsman. At one point, I wanted to be an inventor, and I'd come up with little schemes.

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.

Ultimately, you've got to answer your critics on the track, and I am very much hoping 8.41m is acceptable for people.

It would be pretty special if I could win two Olympic gold medals, one at the Summer Games and one from the Winters, so I'm going to give it a real go.

My favourite series of all time has been 'Band of Brothers.' That was amazing; I've watched that so many times.

I seem to be the 'luckiest' athlete around - and that's one of the most frustrating things. You compete against a vast array of people and train your whole life for those moments.

I've got two chocolate labradors, Murphy and Dexter. They're like my children.

It's all about proving it on the track and proving to people that have different views wrong.

I have been in discussions with the BBC regarding my involvement with SPOTY after hearing what I believe to be very outdated and derogatory comments from a fellow SPOTY nominee.
