A 31 mile point to point journey through the largest coastal dune system in North America. Experience diverse terrain from towering sand dunes to dense coastal forest.

The course winds through old growth Sitka spruce and western hemlock forests before emerging onto expansive dune fields. Cross multiple ecosystems including coastal wetlands and deflation plains. Finish at Honeyman State Park on the shores of Woahink Lake.
