Mary's Walk began in 1999 as a way to remember and honor Mary Kerry Libby, a much-loved member of the Saco-Biddeford community, who passed away from Burkitt's Lymphoma March 7, 1997. Twenty-two years later, Mary's Walk and its companion run, the Kerrymen 5k, have raised over $3,490,000 for the people of Maine and is now one of the largest cancer foundations of its kind. Mary's Walk, a non-profit charity, donates all proceeds to the Maine Cancer Foundation, a state-wide organization focusing on early detection, access to care, and research that support cancer patients and their families.
