About the 2027 The Snohomish River Run Marathon, Half Marathon, 10K and 5K
The course follows the Snohomish River, moving through farmland and stands of evergreens as the route bends with the water. In fall the fields go golden and the tree canopy turns, so the scenery does a lot of the work. The terrain is runner-friendly, without significant climbing, and the river stays close for most of the way.
