Come and be part of the 19th annual Seacoast Half Marathon on Sunday, October 27. The race showcases the scenic beauty of New Hampshire’s historic Seacoast — and 100% of the net proceeds are donated to a carefully chosen Seacoast-area nonprofit organization. The event kicks off and concludes at Portsmouth High School, taking you through the picturesque coastal communities of Rye and New Castle, New Hampshire. Plus, every participant will receive a long-sleeve race shirt and a medal!

Thank you to everyone who helped make the 2024 Seacoast Half Marathon such a successful event! See you next year!

Our 2024 beneficiary is Mainspring, a social services collective that is systematically changing how we care for the region — with a focus on both short-term responses and long-term solutions to hunger, homelessness, and an array of poverty-related issues.
