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

And as long as I'm passionate about the sport, I'm able to do that and I'm happy, then I would love to do another Olympics. I'm just going to see how I'm feeling.

I myself am frustrated in just where sports are at. It's a hard thing when you're out there working every day, and you know that someone else is cheating and they may not necessarily get caught.

Before a race, I block out what's going on in the stadium. It's different for everyone. But for me, I've always been able to block it out. For a sprint race, it's important not to get distracted.

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.

Most people don't think about plyometrics when they think about powerful strength. But I do lots of them to build mine.

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