Cystic fibrosis (CF) is an inherited, life-shortening disease that turns simply breathing into a struggle.

There is no cure, and staying healthy requires a marathon effort.

Join the fight with M4CF as we help people with CF breathe a little easier:

Why We Run

CF is a genetic condition that affects over 30,000 people in the United States.
People with CF battle many serious symptoms, including difficulty with breathing and digesting food.
Lifelong treatment with medications, breathing treatments, nutritional supplements, and exercise improve quality of life, but there is no cure.
At M4CF, we support individuals and families living with CF in a variety of ways. We offer programs to promote regular exercise, provide financial support to individuals and organizations in the CF community, create opportunities for action and service, provide education, and raise awareness.
