Great Bay 5K

The Great Bay 5K 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.

The accompanying Great Bay 55K Challenge represents the distance of a route around Great Bay; participants can complete the mileage in a day or do it in segments, logging miles in as many days as needed between October 1 and October 28. You’ll be able to see on the Leader Board how your total miles compare to others doing this virtual race.  Complete the Great Bay 55K Challenge anywhere you want: on some or all of the mapped course; around your neighborhood or a local lake; on a trail or a treadmill. Look for emails prior to race day about how to log your results for both races. You can also register for both virtual events: the virtual Great Bay 5K and the Great Bay 55K!

All proceeds from the Great Bay 5K and 55K go to the non-profit Great Bay Stewards, which supports conservation, education, community outreach, stewardship, and research of the Great Bay estuary.
