It's really exciting to get the Paralympic sport out there and inspire the next generation - I remember watching the Athens 2004 Paralympic Games that inspired me to want to got to a Paralympic Games.
The Paralympic Games actually turned my whole mentality around about disability. When you're in the Paralympic athletes' village and there are 4,000 disabled people, you stop seeing disability. Totally.
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.
As a 12-year-old when I won my first gold in Athens, I wanted people to know what the Paralympic games were.
I loved the adrenalin rush of the skeleton, and would love to do it as a Paralympic sport if they ever bring it into the Games.
The Paralympic Games is about transforming our perception of the world.
Nobody is on the Paralympic Team until three months before those games.
After a Paralympic Games, I usually take a few months off to enjoy life or go on a family vacation.
It was a true honor to have represented my country at my first Paralympic Winter Games and proud to bring home gold and silver medals for the U.S.
Winning gold and three silver medals at the Paralympic games is something I'll never forget, but I knew deep down there was still more work to do. I had to continue to redefine what was possible and get back everything that was taken away from me.
I'm pretty proud of having completed a marathon myself, so I can only imagine the pride that real athletes feel when they are picked for the Olympic or the Paralympic Games.
Paralympic sport and other disability sport can and should be celebrated in its own right.
Sometimes I'll get reminded that I promote Paralympic sport and Paralympics GB. Yes, I have a role but I don't feel like an idol.
I've achieved my dream of getting a Paralympic gold medal and I'm very lucky that I've been to three Games where I've come away with five gold medals.
There was a time in 2008 where no one really wanted to talk to the Paralympic athletes.
Four Games is incredible. Especially as an nine-year-old watching Athens 2004. To think as a kid then I would not just go to one Games but four.
I've always been a sprinter, I'm muscular. If you put me next to the average sprinter, I would fit in a lot more. But against the Paralympic side, I always feel really big.
