How does radio host Julie Guy stay fit?

Sarah Dussault, Sun Sentinel

After putting on 40 pounds with the birth of her second child, radio host Julie Guy was overwhelmed with the thought of getting back in shape. In 2007, she joined The Leukemia & Lymphoma Society's Team In Training, a local group that trains runners and gives moral support, and hasn't stopped running since.

Why do you keep fit?

For health, to look good, to get rid of stress, to keep up my energy. Once you get on a regular fitness routine, you see the benefits of all of these.

Growing up on Hollywood beach, I was very active. But as my metabolism slowed down with age, I realized I had to keep active for the reasons I mentioned.

I also want to make sure I look good for my husband. That's a bonus.

How did you get started with half marathons?

The radio station was promoting Team In Training and wanted me to do a half marathon, so I got involved with them in 2007. What I love about it, besides being a great charity for leukemia, is that I trained and did a half marathon and got hooked. I like having the goal of training for races.

Have you tried full marathons?

I did the Chicago marathon in 2008 then wanted to beat my time so I did the [one in] Fort Lauderdale. But I've done five or six half marathons. They're much easier to recuperate from, and the training is not as vigorous. But you still get fantastic benefits!

What were your recent races?

[My co-host] Tamara G. and I participated in the Disney Wine & Dine Half Marathon on October 2. I was begging her forever. We did the relay. She did the first part, 5 miles, and I ran 8.3 miles to make up the rest of the half marathon. Then I'm doing the Palm Beach half in December.

What's your training routine?

I typically run four days a week. During the week, some short runs are 3 to 5 miles, depending on what I'm training for. On Saturday morning, very early because it's hot in South Florida, I do a long run of 6 to 8 miles, not past 10 or 11 if training for a half marathon. My shorter runs are by myself, longer ones are with Team In Training.

Where do you run?

Outdoors is much easier on your legs and body. The treadmill is great when it rains or is too hot.

Is running your only fitness activity?

I do CrossFit once a week at Orange Theory Fitness in Fort Lauderdale. I'm in love with CrossFit. It's crazy, hard core. It's a combination of high-energy cardio with weights and ab workouts. You can't always do the same exercises or your body and mind get tired.

We have a pool at home. You can get a great cardio workout in a pool, but I use it as a post-running stretch.

Do you lift weights?
