RUN FOR GOOD

New in 2025, an enhanced community engagement program has been created to allow participants to select and support a local charity organization and help further the positive impacts of this annual Mystic race tradition. Consider making a donation or run, walk or volunteer with their group and support their missions. Learn more about the Child & Family Agency of Southeastern CT, Girls on the Run of Southeastern CT, and the John Kelley Memorial Fund on the Run for Good page.

OUR RACE IS MADE POSSIBLE BY THE GENEROSITY OF THESE PARTNERS
