Fit for a Cause: Real Women Who Are Changing the World

Carol McGarrahan, 47, Raleigh, North Carolina

Raised $72,000 for the National Lung Cancer Partnership

When Carol's best friend, Sara, was diagnosed with lung cancer after being a lifelong nonsmoker, the two knew something had to be done to help raise awareness. Together they helped form the NC Lung Cancer Partnership. Sara passed away last year, but the organization's inaugural Free to Breathe 5K had more than 850 participants. "You see so many others who have been affected by lung cancer, and it makes you realize that you have a chance to make a difference," she says.
