Every dollar raised through the Seacoast Cancer 5K directly benefits patients and families of the Mass General Brigham Cancer Institute at Wentworth-Douglass Hospital and for that reason, refunds are not permitted. You may switch from a Virtual Participant to an In-Person participant until September 19, 2026. If you wish to adjust your registration fee to a donation or have any questions, please contact us at [email protected]. Thank you for your support of Wentworth-Douglass Hospital!
