The 30K and 50K routes ascend the Rim Rock Trail with steep uphill sections and panoramic valley views.

Course maps and elevation charts are available through the event’s mapped routes.
Aid stations are touchless and located roughly every 5 to 9 miles, offering pre-packed food, snacks, hydration, plant-based options, and on-course gels. The event is cupless; runners must bring their own cup, bottle, or hydration bladder for aid stations.
Parking is through the park’s south overflow lot and the $6 parking fee is included with race registration. Camping, RV and tent sites, restrooms, and showers are available through Skyline Wilderness Park; those extras are managed by the park. Final results are posted within 72 hours after the event.
