Dash across islands at Deception Pass
Overview
The Deception Pass 50K is a rugged and scenic ultramarathon hosted by Rainshadow Running at Deception Pass State Park in Oak Harbor, Washington. Runners weave through nearly every corner of the park, from rocky coastlines to mossy forests, and cross the iconic Deception Pass Bridge high above the swirling waters. While there aren’t long mountain climbs, the trails are narrow, technical, and deceptively challenging with constant twists, roots, and short steep pitches. This is one of Rainshadow’s faster courses but still a stout test.
Course
From West Point Amphitheater, runners skirt Cranberry Lake on pavement for a mile before diving onto singletrack that winds through coastal firs, skirts sheer sea cliffs, and twice crosses the iconic Deception Pass Bridge. Expect technical footing, tight switchbacks, and punchy hills that reward you with sweeping views of Puget Sound, the Olympic Mountains, and snow-capped Baker on a clear day.
50K runners tackle a pair of lollipop loops in the Hoypus Hill forest after summiting Goose Rock, while 25K athletes complete one grand loop over the park’s signature features. The kids’ 1K scoots through quiet campground trails and along North Beach, finishing beneath the same roaring arch as the longer distances.
