Deception Pass 13.1M and 10K

Lace up your trail shoes for the Deception Pass 13.1M and 10K, a challenging and incredibly scenic race set for Saturday, April 4, 2026, in Oak Harbor, WA. Hosted by Rainshadow Running, this event plunges runners into the breathtaking landscapes of Deception Pass State Park, renowned for its rugged coastline, dramatic cliffs, and dense forests overlooking the northern Puget Sound. Typical race day conditions in early April offer pleasant temperatures, with highs around 54°F and lows around 40°F, and only an 8% chance of precipitation, providing an ideal climate for tackling the trails.

The courses, starting and finishing at the East Cranberry Lake Picnic Area, begin with a brief stretch on low-traffic paved roads before transitioning to primarily single-track trails. While not featuring extensive mountain climbs, these races are notoriously tough due to technical footing, narrow and twisty paths, and frequent steep grades. Runners should expect a dynamic mix of smooth sections, rocky terrain, and abundant roots, demanding careful foot placement. The 10K route forms a loop on the south side of the iconic Deception Pass Bridge, while the half marathon expands upon this, twice crossing the historic bridge towering 180 feet above the churning waters, and venturing out to Rosario Head, Lighthouse Point, and Lottie Point Trails. The Half Marathon boasts approximately 2,100 feet of elevation gain and loss, with the 10K covering 1,100 feet. Prepare for continuous stunning views of Puget Sound, and on clear days, even the Olympic Mountains and snow-capped Mount Baker.

Aid stations are strategically placed along the route, with the 10K having one before mile 4, and the Half Marathon offering additional support at miles 7 and 10. These well-stocked stops provide water, Nuun electrolyte drink, fresh fruit, chips, and an array of snacks, including peanut butter & jelly sandwiches, cookies, and candy. Half Marathon participants also have the convenience of a drop bag at the Bowman Bay Aid Station. For those seeking an extra challenge, "The Double" allows runners to complete both the Half Marathon and 10K for a combined 19.3 miles and 3,300 feet of elevation gain. Past participants consistently praise the event's exceptional organization, clear course markings, plentiful volunteers, and overall challenging yet rewarding experience. All finishers receive awards and can enjoy a post-race meal and drinks.
