The 30K and 50K routes ascend the Rim Rock Trail with steep uphill sections and panoramic valley views. The 30K and 50K include a roughly nine-mile section served by a water-only stop; runners should carry water and nutrition for that segment. 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.
