Get Ready!

Join us on Oct. 25, 2026, for the 2026 Seacoast Half Marathon. The scenic course winds through the historic coastal communities of Portsmouth, Rye, and New Castle, offering stunning views of New Hampshire’s Seacoast. In a race calendar crowded with corporate, for-profit events, the Seacoast Half is the only purely local, purely charitable race of its kind— and has raised nearly $2 million for worthy area nonprofits.

2026 Beneficiary

This year's beneficiary is Krempels Brain Injury Center, a nonprofit organization dedicated to improving the lives of people living with acquired brain injury through evidence-based programming, shared experiences, and support in a welcoming community.

Krempel's innovative programming is geared toward the unique and varied needs of brain injury survivors. The Krempels community is characterized by a deep and abiding respect for each individual, and the goal of helping each person achieve their maximum potential and satisfaction with life. 

Registration

Registration for the 21st annual Seacoast Half Marathon opens on March 1, 2026! The course is fabulous — fast and mostly flat with a few rolling hills. Starting and finishing at Portsmouth High School, it offers striking views of woodlands, salt marshes, the rugged coastline, working waterways, historic homes, and Portsmouth Harbor. Plus, every participant will receive a long-sleeve race shirt and a medal!
