The pressure is hard. You get - the world is only watching every four years, and I think lots of people feel like they have to win in that time frame.

I'm always nervous. If I wasn't nervous, it would be weird. I get the same feeling at all the big races. It's part of the routine, and I accept it. It means I'm there and I'm ready.

Philippians 1:21 is very special to me because it helps to keep my life centered.

I feel like I'm always going to be me. It always goes back to being the person that I am. And I hope that will never change.

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

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.
