Mary’s Walk began in 1999 as a unique way to recognize and remember Mary Kerry Libby, a much-loved member of the Saco-Biddeford community who passed away from Burkitt’s Lymphoma.

What started as a simple memorial stroll through town with a few hundred people has evolved into a major community effort that has attracted over 50,000 participants in its 19-year span and raised over $2.6 million to support Maine-based cancer programs.
