The Mission of the Seacoast Half Marathon

“Caring for the coast, one step at a time” is our motto. Each year, we donate 100% of the net proceeds to a mindfully selected seacoast nonprofit organization. We strive to put on a well-organized and safe event that highlights the beauty of New Hampshire’s historic seacoast. We encourage all levels of athletes to enjoy themselves while also providing them an opportunity to significantly benefit our community.

2023 Beneficiary – TBD

The Seacoast Half Marathon is one of the longest-running half marathons in coastal New Hampshire. Our race is unique in that all of the revenue (after race expenses) goes to local non-profit beneficiaries.

Our beneficiary application closed on February 1st. Stay tuned for our 2023 race beneficiary announcement in mid-February.
