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

I majored in elementary education, and I have a passion for kids.

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.

If I wasn't active and involved in different sports and just moving around, I wouldn't have even known that I had the potential to become an Olympian.

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 myself am frustrated in just where sports are at. It's a hard thing when you're out there working every day, and you know that someone else is cheating and they may not necessarily get caught.

And as long as I'm passionate about the sport, I'm able to do that and I'm happy, then I would love to do another Olympics. I'm just going to see how I'm feeling.
