I have learned that track doesn't define me. My faith defines me. I'm running because I have been blessed with a gift.

Try to think of working out and healthy eating as a lifestyle. Rather than go on a diet or try a crazy exercise routine, try making them something you do every day.

I can be a voice. I can use my platform to help the younger generation. I think it's really important for them to understand how to do things the right way, and not just in sports, in life in general.

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

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

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.
