Tunnel Vision Half Marathon

The Tunnel Vision Half Marathon offer a beautiful, fast downhill course on the Palouse to Cascade Trail (part of Washington State Parks) and Snoqualmie Valley Trail (part of the King County Parks system).  Both trails are the remains of old railroad tracks. The half begins at precisely the halfway point of the full marathon and is point-to-point ending at the finish line of the full marathon. Runners will enjoy an 1100-foot net drop from start to finish. You will be treated to stunning mountain and waterfall views while taking in the sweet Washington air. The half course is USATF certified.

HALF MARATHON BUS DROP OFF

Half Marathon runners will be dropped off by bus transportation we provide. RUNNERS WILL NEED TO WALK one mile up a scenic dirt road to the start. Trust us, the half marathon is worth the short hike/warm-up to the start.  We promise you will not be disappointed!

 

HALF MARATHON PARKING

Half Marathon runners will park in the designated parking area at Snoqualmie Summit (Same as marathon runners). View parking HERE

You will load buses and be taken to the half marathon start location. (Exit 38 off I-90) It is a bit remote, and the permitting agencies allow our team to drop runners at the end of the paved road/bottom of Garcia Trail, where you will walk approx. one mile to the start. It is well worth the short walk/warm-up, trust us!

 

THE COURSE

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.
