Cool conditions, gradual warming ahead

Runners will face temperatures starting at 51°F and rising to 59°F by the finish. With light winds at 6 mph, the first miles will present crosswinds and headwinds, particularly challenging from miles 2, 13-14, and 16-17. As the race progresses, a tailwind from mile 9 may aid pacing, but runners should stay hydrated and pace conservatively to manage the gradual temperature increase.

Race Info

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. Source
