The race is held on Sandy Neck Beach in Barnstable, MA. The course consists of two 15.5 mile figure eight loops. The first loop is around 5 miles and the second loop is around 10. Each loop runs along the beach, through some sand dunes, and along a marsh trail. Parts of the trails can be wet or frozen or both, depending on the tides. The race is scheduled according to the tides to give the runners the driest course. 

The course is half front beach (adjacent to Cape Cod Bay) which is a mix of loose sand, gravel and cobble, and half through scrub pine forest and along salt marsh, which is mostly a mix of hard packed and very loose packed sand.
