Race Information
The Tunnel Light Marathon race offers one of the fastest courses in the country. This point-to-point course delivers excellent times thanks to the consistent downhill grade and low starting elevation. It is the perfect race to set a Personal Record and snag a Boston Qualification on a single course.
You will start at Snoqualmie Pass and run through a dark tunnel lit by your best running mates, gawk at the mountains and waterfalls, take in the sweet Washington air, and let your legs take you to the finish in North Bend. The speed of the course comes from a loss of just over 2,000' of elevation at a consistent grade of approximately 2.2%.
