The race village is located at the Massey Hill Shelter, which provides access to a fire pit, tables, and permanent bathroom facilities. An aid station is positioned at the transition point between the two trail loops, offering water and electrolyte drinks. Specialized awards, including custom belt buckles, are provided for finishers of the 100 Mile, 100K, 50 Mile, and 50K distances. Overall male and female awards are presented across all categories.
Logistical amenities include camping areas in the parking lot and grass near the shelter for participants. The event allows pacers for the 100 Mile and 100K distances after the 50-mile mark.
