I am also hugely excited to then be competing to defend my three Paralympic titles at the Paralympic Games. I believe we will see some amazing times posted and I am very much looking forward to what will be an incredible Olympics and Paralympics in London.

Thank you to everyone that has made me the athlete I am! God, family and friends, my competitors and supporters! You have all had a hand!

There is a big difference between being good and being great.

I wasn't happy with my performance at the World Championships in Daegu. I had an unbelievable race in the heats, but misjudged the semi and finished last.

I'd like to show people that if you put the hard work in and you believe in yourself, then you can do whatever you want to.

Out of the tens of thousands of prosthetic legs they've made, there's never been any 400-meter athletes run under 50 seconds. So, if this was such a technologically advanced prosthetic leg, then how come not everyone's qualifying, or coming close to the qualification time, then?

Being disabled doesn't have to be a disadvantage.
