The course is approximately 101 miles (because why stop at 100, #amiright?), with over 9,000 feet of elevation gain/loss. This is a self-sufficient race. No drop bags, no pacers, no cell service. Check points are separated by upwards of 25 miles of varied conditions and temperatures. Much of the course is along the Continental Divide; as Drifters will be both navigating back and forth over the Divide itself and traversing it, you will reach elevations just shy of 10,000 feet.
