24 Hour Endurance Run… Solo and Relay. Held at Addison Oaks County Park, Michigan. Course will be a mixture of surfaces and trail types. Single track, Wide track, Dirt, Paved, Gravel and approximately 80-100 feet of elevation per 2 mile loop. Nice mixture to change things up and keep your mind occupied. Course will also change directions at the TWILIGHT Hour (right before dark)... this will make it feel like a totally different course!!!
