Grey Rock Trail Runs

Lace up for an unforgettable challenge at the Grey Rock Trail Runs on July 11, 2026, nestled in the scenic Cascade Mountains near Yakima, Washington. This highly anticipated event, offering both a formidable 25K and a rigorous 12K, begins and ends at the serene Tree Phones Campground in the Ahtanum State Forest. Runners will tackle tough and rugged singletrack trails, characterized by an impressive 3500 feet of elevation gain for the 25K, making it a course not to be underestimated. The route promises breathtaking panoramic views of both Mt. Rainier and Mt. Adams as it winds through open ridges, dense forests of ponderosa pine and Douglas-fir, and expansive meadows, occasionally revealing areas shaped by past fires.

While typical mid-July conditions in the region see highs around 91°F and lows around 56°F with no precipitation, the higher mountain elevation on the course helps moderate temperatures, though it can still become quite warm by midday. Runners are advised to carry their own water and snacks, supplementing the aid station at the 25K turnaround point, which provides water, electrolyte drinks, power bars, and gels. This out-and-back course is renowned for its steady climbs and technical sections, rewarding participants with stunning vistas and a true sense of accomplishment.

The Grey Rock Trail Runs, hosted by the Hard Core Runners Club, has a long-standing reputation for delivering a challenging yet profoundly beautiful trail experience. Past participants have lauded the well-maintained trails and the spectacular views of the volcanoes that greet them along the way. A Discover Pass is required for parking at Tree Phones Campground, ensuring access to this incredible mountain escape. Prepare for an exhilarating journey through Washington's majestic wilderness and discover why this event is a highlight for trail runners.
