I have so much to learn when it comes to running. I just don't ever want it to feel like a chore. When I choose to sign up for a race or go out for a run, it's to make myself feel good, and I almost always do.

Tennis is interesting because the women are almost more popular than the men. In the U.S. Open, women even get exactly the same money as the men.

When I was younger, I would eat everything.

It really was my brother who got me involved in swimming. I wanted to be just like him and do everything he was doing.

I lead by example. My kids know what sweat is. They've seen me come home from so many runs and asked, 'What's on your skin? How did you get it?' And I tell them, 'It's from exercise!' So now my son will come home from a bike ride, take off his helmet and say, 'Look, Mom. I'm sweating! I just worked out!'

Sports have always been a huge part of my life and my conversations. It is a thrill and an honor to be a part of this ground-breaking show. I am a competitor at heart, but a true sports fan to my core.

For as long as I wanted to swim, I also wanted to do something on TV. My best friend in high school, we used to pretend like we had a TV show, and we had this dream of being the next 'Kate Allie.' Having that kind of a shtick.
