Out of the Darkness & Into the Bighorns

This beautiful course starts near the Ten Sleep Fish Hatchery and Leigh Creek Campground. You cross the bridge over the rushing creek and start the descent up the windy Old Ten Sleep Highway. It's a hard packed dirt road but does get rockier as you get closer to the turnaround point at 6.6 miles. It's a steep climb up 2083 feet to the top and a quick and fun descent back down to the start.

Aid Stations
The first aid station is at 1.6 Miles - the 5k turnaround point. There is water only at this aid station.
There is a porta-potty and aid station at mile 2.5. This aid station is has water, gatorade and gels. You might even score some gummy bears here.
