When people say, 'Hey, wanna come to our house for dinner?' I say, 'Yeah, what should I bring?' They say, 'How about the dessert?' I just don't skimp on the dessert. I make it the yummy way it should be made, and then I just don't eat the whole pan.

I think some parents fall into a trap, teaching their kids that everything is always perfect and everyone is always a winner.

The kids know what I'm doing when I exercise, and that's powerful. So don't just tell your kids to go play outside. Take a moment off your computer, put on your tennis shoes, hop outside and help them start their game and run off some energy.

To be a champion, I think you have to see the big picture. It's not about winning and losing; it's about every day hard work and about thriving on a challenge. It's about embracing the pain that you'll experience at the end of a race and not being afraid. I think people think too hard and get afraid of a certain challenge.

The things you learn from sports - setting goals, being part of a team, confidence - that's invaluable. It's not about trophies and ribbons. It's about being on time for practice, accepting challenges and being fearful of the elements.

When I was training for the Olympics, I didn't eat the way I should have. I missed out on much-needed protein and opted for every easy carb.

The first mile is mental. The rest are all heart.
