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

The biggest way I stay motivated is to run with a group of friends. Sometimes it's hard to get going by yourself, but if you have a plan and a meeting time, you know this run will happen for sure. It's a way to have fun - while also getting in a workout. Plus it distracts from pain, helps you fight fatigue, and gives you that extra push.

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.

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

I am a big believer in visualization. I run through my races mentally so that I feel even more prepared.

My mom is great and I make sure that we pray together before every race. She helps me put everything in perspective and remind me of the real reason I run.

There was a race that I was running in Mexico City and I was the only high school athlete running against grown women. It was a professional race, but I ended up winning. That was kind of a turning point for me where I felt like, "Okay, I'm pretty good at this and there's a possibility for this to be a career for me." That was a defining moment for me.

I focused solely on the sprints, dedicated my time there, got in the weight room, just really did everything I could to make sure I would be in the best position to run for gold.

When I was younger, Jackie Joyner-Kersee was a mentor to me and gave me great advice. The best was to 'work 100 percent, but enjoy every moment along the way.' Sometimes you get so in the zone, you forget to enjoy your passions. I love running—but I also love the movies, relaxing on the beach, shopping and spending time with my friends. Enjoying my life helps me enjoy my running.
