Whitehorse Half Marathon

Join us for the 2026 Whitehorse Oso Strong Half Marathon, a scenic and heartfelt 13.1-mile out-and-back run through the Stillaguamish Valley. Starting at the Fortson Mill Trailhead and reaching the Oso Slide Memorial loop, this event blends natural beauty with community remembrance and resilience.

Runners and walkers of all levels are welcome. Each participant will receive chip-timed results, a finisher medal, and an event T-shirt for registrations completed by March 15. Awards will be presented to the Top 3 Male and Female finishers.

A portion of event fees will be donated to the Community Foundation of Snohomish County to support long-term care of the Oso Slide Memorial.
