It's one of the greatest honors I could ever imagine - to be able to represent my country and to be able to wear "USA" on my back. It's an incredible honor. It's an accomplishment of the past four year but of a life of dreaming and working hard and doing everything I can in pursuit of this goal.

I grew up in Douglasville, Georgia. My father played football for the Atlanta Falcons. We lived a bunch of places when I was younger. I was born in California. We lived in Chicago for a little bit and finally we ended up in Georgia. I grew up playing softball and at the age of nine I decided I was going to be an Olympian.

I'm a representative of something that's greater than myself. When you see me out there on the track, I'm not just representing myself or my country, I'm representing Christ and what He's done through me. I have a responsibility to show His love and show others what He's done for me. It's also freed me up.

I like to compare the two to a quarterback and a lineman. Being a brakeman is very physical and success is mostly determined by how fast you can push a sled for about 30 meters. Your position is won or lost by the hundredths of seconds you are faster than another individual. It's like the lineman who is there mostly for their athleticism and physicality. The driver, like the quarterback, possesses a unique skill that takes a lot longer to learn.

It's a huge testament to those around me - my friends, my family and everyone who supported me. Without their help, I couldn't have made it here. It's been an amazing journey. But we are here for a higher purpose There's a reason that God has for each of us in the sport. It's all about serving His purpose.

We're talking about the Olympics. We're talking about trying to win the gold medal. All of these things can be overwhelming. But regardless of whether I win a gold medal or never compete again, I just have to trust that God has a plan for my life and I'm called to be His representative through the sport and outside of the sport.
