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

My faith is the reason I run - it calms my heart and makes everything feel like a lift. My speed is definitely a gift from Him, and I run for His glory. Whatever I do, He allows me to do it.

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

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.

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

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.

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.
