Back 9 Endurance Run

The Back 9 Endurance Run is a timed endurance event held on a 3.68 mile loop at Keweenaw Mountain Lodge in Copper Harbor, Michigan. The course combines wooded trails, the Back 9 Trails, and paths across the lodge's historic wilderness golf course, with periodic views of Brockway Mountain and Lake Superior inside the Keweenaw Dark Sky Park.

Event formats include:

• 24 hour solo
• 24 hour teams of 2
• 24 hour teams of 4
• 12 hour solo
• 12 hour teams of 2
• 12 hour teams of 4

Key competition rules require only one team member on the course at a time. Teams must start a new lap at least once every hour; solo runners must start a new loop at least once every 2 hours. No partial laps are counted; final results use the last completed lap. Lap times are entered by runners on a timing board using an honor system.

Runners are responsible for personal shelter, clothing, food, hydration, and outdoor survival gear. The event will provide a warm-up shack and some food and hydration. Required gear includes a headlamp with extra batteries, rain gear, extra socks, a warm outer layer, hat, and gloves. Littering is prohibited. Race officials may cancel for extreme weather and may evaluate a runner's condition for safety. Visit the organization's website for the most recent information.
