About this event

The Snohomish River Run offers something for every distance goal, from a manageable 5K to a 10K, half marathon and full marathon along the river and trails near historic downtown Snohomish. Fall foliage and flat riverside paths make it a favorite for both first-timers and marathoners chasing a time. Walkers are welcome in the shorter events, and the small-town start/finish keeps the vibe friendly. Pick your distance, enjoy the scenery, and celebrate at the finish. Registration is required with an entry fee; consult the event page for start times, course maps and packet pickup.
