Event overview

The Winter Solstice Vertical Challenge returns for its fifth year on Saturday, December 20, 2025, at the Mt. Walker trailhead in Quilcene, Washington, inside Olympic National Forest. The event uses a "fatass" format in which participants may run or hike as many laps as they wish. Aid will be available at the trailhead, and nutrition is donated by Skratch Labs. A photographer will be on course. Dogs are allowed if kept on a leash and cleaned up after. After event costs are covered, proceeds will go to the Washington Trail Association. Organizers request volunteers for morning set up and evening breakdown.
