I've got to make sure I'm keeping weight on.

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.

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.

I love the relays. Track is such an individual sport, so it's fun to do something together.

It was all kind of a whirlwind at the beginning. I didn't really realize that I had a special gift from God. It was probably towards the end of high school in my senior year when things really started to come together and I realized that I had more potential and that I could do this as a career and that the Olympics were a possibility.

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

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.
