Cool conditions, mild tailwind

Runners will face a steady temperature rise from 51°F at the start to 55°F by the finish. With light winds from the NNW, a tailwind will assist in the early miles before shifting to headwinds through the later segments. Runners should maintain a steady pace and stay hydrated, particularly as they navigate headwinds from miles 6 to 10 and 19 to 22, ensuring they conserve energy on those stretches.

About the Cascade Express Marathon

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
