Course and logistics
The courses combine paved road, forest service road and dirt trail. All races begin with a 3/4-mile loop along the lake. The route climbs gradually up Green Valley Lake Road onto Forest Service Road 2N13, with about a 400 ft elevation gain to a viewpoint near the 5K turnaround. The course includes 1.5 miles of paved surface before transitioning to dirt roads and trail. The half marathon is an out-and-back route that repeats the initial lake loop to reach 13.1 miles; organizers list five aid stations for the half marathon and water or aid stations approximately every 1.5 miles for the event. Chip timing is provided by Itz About Time. Packet pickup is available the Friday before the race at Black Dog Social Club and on race day at the race site.
