Race for a Healthy Estuary

Enrich your life by supporting the Great Bay 5K | Race for a Healthy Estuary!

The Great Bay 5K | Race for a Healthy Estuary is a wicked-fast, scenic, point-to-point race that will be held at 9:00am on October 24, 2020. The race features the unique Mackenzie Mile, bib-chip timing, long-sleeve race shirts, great views of Great Bay from the course, a free kid’s Fun Run, and lots of great post-race eats. The race is a fundraiser for the non-profit Great Bay Stewards and the Great Bay Discovery Center. We offer many ways to assist with our mission of supporting the Great Bay in addition to supporting New England’s famous 5K!
