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.

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

I am a sprinter, and I love to go fast. It's very difficult for me to be patient and follow a race strategy or conserve energy.

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.

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.

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

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.
