Seward Solstice Trail Run

Take your pick of 4.2-mile and 10k run distances among the towering old-growth trees on this forested peninsula. We encourage costumes at this run and award prizes to the best holiday-themed outfits!

Northwest Trail Runs events feature clearly-marked courses, well-stocked aid stations, friendly staff, and fun raffle and winner prizes given at the finish.

Surrounded by Lake Washington, Seward Park provides perhaps one of the greatest contrasts in Seattle: 100+ acres of old growth forest, just minutes from the city center. The run route follows a loop that is almost entirely in the forest, so there is ample opportunity to enjoy what the Friends of Seward Park fondly call The Magnificent Forest with graceful Western Red Cedar and towering Douglas Fir, along with a lush tapestry of other native plants. You may even hear a Pileated Woodpecker pecking out a nest or rooting for a meal in an old tree trunk.
