Grey Rock Trail Runs - Yakima, WA
Grey Rock Trail Runs are summer trail events held near Yakima, Washington in the Cascade Mountains, presented in their 16th year. The courses start at Tree Phones Campground in the Ahtanum State Forest and follow an out and back single-track route. The 25K course includes over 3500 ft of elevation gain and the trail contains both rocky and smooth forest sections.
The route offers views of Mt. Rainier and Mt. Adams, open ridges and forested stretches. The higher mountain elevation tends to keep temperatures lower, but conditions can still become very warm by mid day. Aid stations provide water, electrolyte drinks, power bars and gels at the 25K turnaround; participants are also advised to carry water and snacks.
Distances
- 25K - Out and back single track with over 3500 ft elevation gain.
