The half marathon climb is an out-and-back that begins on Maple Springs Road, outside of Silverado, CA. Runners follow the creek on a gradually inclining, beat-up asphalt road for about 1.5 miles. The climb picks up at the dirt truck trail where runners switchback up the mountain toward Dead Man’s curve and beyond to Four Corners (where Harding Truck Trail and N. Main Divide come together with Maple Springs Rd). Runners continue the climb to N. Main Divide where they travel a short distance down to the turnaround point before returning to the Finish.
