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

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.

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

My mom always has this amazing ability to always see the best in a situation.

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

Competing at the Olympics is the pinnacle of your career. Everything is amplified, and you feel so proud to represent your country. You're there with athletes from all over the world. Everyone is coming together, putting differences aside.

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