Hosted in scenic Carnation, Washington, this event offers both a Half Marathon (13.1M) and a 10K, making it perfect for runners aiming for a personal best or those simply looking to enjoy a picturesque journey.

The out-and-back route begins and ends at King County's Tolt MacDonald Park, where you'll find a spectacular finish in the shadow of the historic big red barn. While the course generally offers a gradual uphill on the way out, the return leg provides a welcome gentle downhill, aiding in a strong finish. Aid stations are strategically placed at approximately miles 2.9, 5.9, 7, and 10.2 for half-marathon participants, providing water, Tailwind electrolyte drink, and GU gels to keep you energized.

The Snoqualmie Valley Half consistently earns high praise from runners, with a 4.6 overall rating, lauded for its excellent organization, beautiful scenery, and suitability for both seasoned athletes and first-time half marathoners. Pacers are also available to help runners achieve their goal finish times, adding to the supportive atmosphere of this Orca Running event.
