Deception Pass Half Marathon & 10K
The event is a set of trail races held at Deception Pass State Park, with start and finish at the East Cranberry Lake Picnic Area. Courses run along park roads and mostly single-track trails that alternate between near sea level and coastal bluffs. Trails include rocky and rooty sections, narrow and twisty single track, and occasional steep short grades. The half marathon crosses the Deception Pass Bridge twice; the bridge sits about 180 feet above the water.

The half marathon has three aid stations and allows a drop bag at Bowman Bay; the 10K has one aid station and does not allow drop bags.
