For 31 years proceeds have gone to Down East Hospice, the only volunteer hospice program of cost-free comfort care for the terminally ill, the grieving, and their families throughout Washington County, Maine since 1981. Down East Hospice is celebrating 41 years of compassionate care!

The Cobscook Bay Races had its genesis in the early 1990s, as an effort to create a certified 10-kilometer road race in Washington County, Maine. Our paved and gravel course, which begins near Route 1 in Pembroke, follows the western reaches of Cobscook Bay—the easternmost saltwater bay in the United States—and finishes at Pembroke’s majestic Reversing Falls.

Over the years, the Cobscook Bay Races have brought together our small, coastal communities—participants, volunteers, and local businesses––in support of Down East Hospice. We have shared the special beauty and character of the Quoddy region with participants from all over the US and Canada. Runners and walkers of all ages and abilities have competed in the challenging 10K and 5K courses and the (10 and under) 1-Mile Fun Run.

The course records for the 10K (Judson Cake, 32:59 ; Sarah Mulcahy, 39:07) were hard-earned on this challenging course—particularly in the approach to the finish at Reversing Falls.
