Fall is a popular time for charity walks and runs. There are several Susan G. Komen marathons scheduled to benefit breast cancer research. The Alzheimer Foundation has Memory Walks scheduled around the country. Step Out Walk to Fight Diabetes has many fall events. And that's just naming a few!

Participating in a charity walk or run is a great way to get in shape. You have all the traditional perks of training for an event, plus you have the added motivation that your actions are a benefit to a worthy cause.

If you're planning to sign up for a charity walk or run, it's time to start training. You can consult a personal trainer for a customized training program. Or, check out the web site for your charity race. Many, such as the Leukemia and Lymphoma Society, have training programs designed for their participants.
