Race Information

Set your new personal record and qualify for the Boston marathon on this beautiful downhill course. The Tunnel Vision 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%.

Half Marathoners will enjoy the same fast, downhill, and beautifully scenic course on the second half of the full marathon course. Half marathon runners DO NOT run through the Snoqualmie Tunnel since it is at the beginning of the marathon course, so there is no need for a headlamp/light. The trail is packed gravel, so both trail and road shoes work great.
