There is nothing in this world that I love more than my family. To be able to share the joy of running with them at the Runner's World Half Marathon and Running Festival where we can all participate together is as close as you can get to a perfect weekend.

You can't go wrong with some nuts. The key word is 'some.' Eat them one at a time, not by the handful.

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.

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.

I love to run, but training can be hard, especially with a family and a crazy travel schedule. I often do sprints with my kids, where they bike and I run along side them so we can 'race' each other for a quarter-mile or shorter repeats.

It's not really about the competition. Your biggest challenge in a race is yourself. You're often racing against time. You're frequently running everything through your mind. You're always competing against preconceived ideas. It's not really the person next to you that you worry about.

At the end of a marathon, it's going to hurt whether you're speeding up or slowing down. You may as well push.
