I've heard so many stories of young girls watching the Olympics and being inspired by it, and they want to do it now, and that's really cool.

Before a race, I block out what's going on in the stadium. It's different for everyone. But for me, I've always been able to block it out. For a sprint race, it's important not to get distracted.

My mom always has this amazing ability to always see the best in a situation. In that moment [when finished 2nd in the 200 meter race in the 2008 Olympic games] I was just completely devastated. I mean, I had worked so hard; that was my opportunity. And she was just able to turn it around for me. She helped me to be able to see the other side of things and that this is not the end for me. She's just an amazing supporter and an encouraging person and she has a unique ability to do that. And so those are the kind of things she said to me in that moment and over the next four years. When things get tough, she's always been my strength.

My dad's a pastor and a seminary professor, my mom, she has such great faith.

I never let track define me. That's something that's really important to me.

My faith inspires me so much. It is the very reason that I run. I feel that my running is completely a gift from God and it is my responsibility to use it to glorify him.

As a female athlete, you're always fighting to be on a level playing field with your male counterparts. But I believe the Olympics is great for young girls; they get to be exposed to so many different sports and to these really strong women. It's an opportunity to showcase what we do, which is something that men get the opportunity to do on a pretty regular basis.
