Great Bay 5K | Race for a Healthy Estuary

The Great Bay 5K is excited to hold its 26th annual race in 2024!  The GB5K is the final race in the popular Seacoast Road Race Series and supports the non-profit Great Bay Stewards. The course passes the shores of Great Bay, and is a fun, fast, scenic, and mostly downhill event. Again in 2024, you can run or walk or use your wheelchair at the Great Bay 5K, or you can participate in the virtual 5K on any course you choose between October 1 - 26. 

Wheelchair racers are welcome and will start at 8:45 a.m, prior to the 9 a.m. runner/walker start. No motorized wheelchairs are permitted, and wheelchair racers are responsible for maintaining their own equipment

Participants in the 5K events will receive a long-sleeve race shirt and everyone will get a bib with tear strips that you can take to select establishments for free beer/cider and free oysters. Please keep in mind that you must register by October 1 to get a race shirt or hat. People who register after that may claim a shirt if any are left over on race day.

All proceeds from the Great Bay 5K go to the non-profit Great Bay Stewards, which supports conservation, education, community outreach, stewardship, and research of the Great Bay estuary.
