Terrain is mostly flat and well graded but includes large roots, rocks, and puddles. Reported elevation gain is approximately 200 feet for the 5K, 700 feet for the 10K, and 1,400 feet for the half.
Aid stations provide Tailwind electrolyte drinks, fresh fruit, gels, gummies, and other snacks. Aid station locations include mile 4.5 on the 10K, and miles 4.5, 6.5, and 11 on the half. Trails remain open to other users during the event, including equestrians, cyclists, and pedestrians. Parking is available at the Soaring Eagle lot and on the south side of E. Main Dr; street parking may require a short walk to the trailhead. Visit the organization's website for the most recent information.
