The Seacoast Road Race Series is comprised of seven unique races.

They have joined forces to promote running for sport, fun and fitness, and the beauty of running on the Seacoast.

A special feature of these races is that each one is a fundraiser for a local non-profit, so your race entry fees will help each organization achieve its goals!

Runners who sign up for the Series will be eligible for the Seacoast Series apparel. (Plus, enjoying great events with terrific people!)

There is no cost to enter the Seacoast Road Race Series; however, individual race fees still apply.

Join for a fun run 5K in support of National Ovarian Cancer Coalition (NOCC), as we raise funds for Team Teal at the 2026 BMW Berlin Marathon.

The mission of NOCC is to save lives through the prevention and cure of ovarian cancer and to improve the quality of life for survivors and their caregivers. To learn more, visit www.ovarian.org.

This local charity run is about more than miles, it’s about honoring those impacted by ovarian cancer. Whether you’re running, jogging, walking, or cheering from the sidelines, every step helps support NOCC and their mission.

All proceeds from this event will directly benefit Team Teal.

Come out, WEAR TEAL, and make a difference! Kids & dogs welcome!

This is a fun run, not a race so there will be no official timing or pace pressure. Good vibes only! (Run Course)

Over 80% of members receive financial aid from Krempels Brain Injury Center to attend programs, with 50% attending for free. Proceeds from fundraising and sponsorships go directly towards programming to help survivors with skill building and social connection to improve their quality of life following brain injury.

Each year, the 10K Road Race gets the Market Square Day celebration off on the right foot. With a starting line in the heart of Downtown Portsmouth, the Race typically draws nearly 1,000 runners who wind their way through the streets of Portsmouth ending with the finish line at historic Strawbery Banke.

In 2005, we joined forces with other area races to create the Seacoast Road Race Series. From May through November, runners participate in races ranging in distance from 5K – 10K in communities throughout the Seacoast. The Series creates healthy (literally) competition and serves to introduce runners to a variety of races. The Series expanded to seven races and continues its popular ‘run’ with new and seasoned athletes.
