About the race

The Sun Mountain races are trail running events in Winthrop, Washington on May 1 and 2, 2027. The courses lie on the sunny eastern side of the North Cascades near the Chelan Sawtooth Wilderness above the Methow and Twisp river valleys. Runners pass through wildflower meadows, old-growth forest and ridgetops with views of snow-capped peaks. Trails are mostly gradual and runnable with some steep climbs and a mix of single track, wider ranch roads, low-traffic dirt and short paved sections.
