Race Overview
The Cascade Express Marathon and Half Marathon run point-to-point on the Palouse to Cascades Trail, starting at Hyak Trailhead near Snoqualmie Pass and descending through the Cascade Mountains past Keechelus Lake to North Bend. The half marathon enters the historic 2.4-mile Snoqualmie Tunnel about half a mile after the start. The marathon's net elevation loss is kept under 1,500 feet so no Boston Marathon downhill time penalty applies. Both distances are USATF-certified and organized by Run Super Series.
