Daily repetition matters when a kid is learning to swim. It can be 20 minutes in a lesson or an hour practicing for a couple of weeks.

I grew up in northern California, where it was consistently in the hundreds in the summertime. My dad didn't think he should have to turn on the air conditioning when we had a swimming pool in our backyard; it was our built-in air conditioner.

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.

Boston is the cream of the crop of the marathon world. It has such history that you feel such honor just being a part of it. All the other races have pacers to get you to a Boston qualifying time.

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!'

Don't just tell your kids to be active and to get outside and play. Lead by example.

At 4, I joined a summer rec team called the Sugar Bears.
