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.
2022 Beneficiary – Portsmouth NH 400
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.
This year, the Seacoast Half Marathon Race Committee is excited to welcome Portsmouth NH 400 as our 2022 race beneficiary. Get ready to run through history and help the City of Portsmouth prepare to celebrate its 400th anniversary, which is just one year away!
PNH400 was founded to spark the city’s collective imagination by leveraging the talent of its multifaceted population and many organizations to ensure that the 400th anniversary in 2023 is a diverse, fun and inclusive celebration like no other.
PNH400 also hopes to bring renewed energy to efforts to invest in and preserve the city’s history, nonprofit organizations, arts and culture and overall quality of life. Proceeds from the Seacoast Half Marathon will help offset program/event costs so they can be affordable and/or free for the community.
“This is an honor and an incredible opportunity,” said Susan Labrie, head of the PNH400 board. “The Seacoast Half Marathon has a legacy of simultaneously supporting and building community, and we can’t wait to work with them.”
In addition to winding through The City of Portsmouth, the Seacoast Half Marathon’s 13.1-mile route includes the beautiful, historic towns of Rye and New Castle that are also celebrating 400 years in 2023. This is a unique time, and we look forward to running through history together on Sunday, October 30th.
