Athlete

My campaign is about getting pets to be more active, and exercise with your animal is a great way for people to exercise. When you're out with your pet, it becomes fun. You don't think of it as a chore. For me, taking my dog out for a walk is very relaxing.

I didn't think I'd be going for another Olympics.

I think the most surprising thing about the Olympics would be the amount of interaction and partying that goes on behind the scenes. They have nightclubs at the Olympic Village. It's like college all over again.

My favorite power food is Greek yogurt and honey.

Over the years, I've made many sacrifices to win two Olympic gold medals and put together winning streaks that will never be broken.

I juice everything! Whether it's beet, carrot, or apple, I'll juice it. I always keep brown rice in the kitchen. I'll often pack a cooler full of food to have throughout the day when I'm busy.

If there are fresh-baked chocolate chip cookies on the table, I won't say no to those. Soy sauce is another one, even though it's awful - it's so high in sodium.

I've never been outside Heathrow so it will be exciting to see what London has to offer. I think I've only flown into Heathrow maybe twice.

I'm an avid animal lover. When I was 16, I wanted to be a vet or a zookeeper. I grew up with animals. At one time we had between five and eight dogs in the house, with four cats. We're menagerie people.
