Q. Hi Fitz. I've just begun jogging as a part of my fitness routine. I've traditionally walked a lot and jumped rope. My husband, Aaron, is trying to convince me to run a 5K race with him within the next few weeks. I don't think I can run it all! Do you have any expert advice that will help me get out of it? Thanks. Amy

A. No can do, Amy! I suggest you sign up to complete that race and get the fancy t-shirt that goes with it as soon as possible. Nothing motivates like an upcoming athletic event. Look at it this way. You are a new runner, and that's fine! In fact, it's terrific. We already know you wouldn't be racing to win, right? You'd just be going out to get some exercise and probably support some charitable cause. That alone makes you a winner. Jog as much as you can, and fill in the spots when you get tired with all of that walking you've been doing.

Trust me. I've participated in a bunch of 5K races, and haven't won one. I didn't care, nor did anyone else around me. It's a ton of fun to lace up your kicks and get moving with hundreds or thousands of others. I bet you'll enjoy it so much that you start looking for another race as soon as you're done. Thank your husband for the invitation and the motivation. Then let him know that you're eager to cover the distance at a pace that feels good to you. If he moves faster, he can wait at the finish line with a kiss for you as you cross it. Have fun and let me know how it goes! Fitz

Q. Miss Fitz. I was startled to read that the woman who won the New York Marathon had a nine month old baby. Isn't that really unhealthy? I was shocked! Mark.

Howdy Mark. On the contrary. I thought Paula Radcliff's win this past Sunday was more of a high five to new Moms everywhere who are embracing a fit lifestyle. Plus, this woman was an athlete to begin with. She's been a competitive runner for a long time, and she loves it! I read some stories after her win with comments of shock and horror on how horrible it was for her to compete in this marathon. From what I can tell, Paula looked perfect and her daughter seemed thrilled to be hugged by her sweaty Mommy at the finish line.

In fact,I imagine little Isla enjoyed lots of cozy naps in a jogging stroller surrounded by fresh air. Many women are approved to run during pregnancy by their doctors as long as it feels good. What in the world would stop a woman from competing in any sport once her child was safely out of the womb? I think Paula Radcliff is a wonderful role model to women around the world. We CAN return to our prepregnancy fitness levels. We DON'T have to settle for postpartum 'baby weight' that never goes away. Poo poo on that. Congrats to her and to all of the other females like her who embrace motherhood and their personal goals as well.
