I grew up in my mom's third grade classroom and always helping her, and I also got a passion for kids that way.

I'm passionate about my sport and grateful that I get to do it for a living.

My speed is a gift from God, and I run for His glory. Whatever I do, it all comes from him.

I'm an athlete who's very determined and I understand sacrifice.

I always look back to my first Olympic medal in 2004 in Athens. I was very new to the sport, and it was my first big win at the Olympics.

Everyone sees the glory moments, but they don't see what happens behind the scenes.

I grew up in a Christian home with amazing parents.
