Course and logistics

The 10-mile loop has a net elevation change of about 430 feet per loop, starting near 1903 ft and peaking near 2333 ft. The first mile is a steep climb, miles 1–5 include continued climbing and rolling hills, an aid station sits near the halfway point of each loop, miles 5–9 are a mid-course plateau, and the final mile is a steep technical descent back to the parking lot. Terrain is predominantly packed dirt and rocky singletrack with open desert vistas. The 0.5-mile out-and-back for the 50K and 100K is on a flat, paved bike path. Recommended gear noted in the event materials includes trail shoes with good grip and sun protection; longer-distance runners may plan for spare shoes or socks and carry extra fluids between aid stations.
