Comfortable temps, warming through the race

Mild 54°F temps at gun time mean comfortable early miles without overheating risk. Temperatures rising to 66°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing. Moderate humidity at 71% is worth noting for effort level, especially in later miles.

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
