Organized by Tunnel Marathons, the Tunnel Vision Marathon will take place on August 10, 2025, starting at Hyak Sno Park Lot at Snoqualmie Pass and finishing just east of North Bend, Washington. The event offers both full marathon and half marathon distances, both following a point-to-point course that begins with a unique experience as runners traverse the Snoqualmie Tunnel, a dark, unlit passage stretching over two miles—headlamps are essential. Emerging from the tunnel, participants are greeted by breathtaking views of mountains and waterfalls as they continue along a gentle, consistent downhill grade, descending over 2,000 feet to the finish line. This USATF-certified course is celebrated for its speed, with a significant percentage of runners achieving Boston Marathon qualifying times. The event includes well-stocked aid stations, drop bag services, and a welcoming post-race atmosphere, making it a favorite among marathon enthusiasts seeking both challenge and beauty.
