The Wrath of Krampus: Last Person Standing
About the race
The Wrath of Krampus is a Last Person Standing backyard ultra where runners must complete a 4.167-mile loop every hour until only one remains. When the bell rings, you must be ready to go again!
The darkness is coming. The bell is waiting. And Krampus wants to know how far you’re willing to go.
Whether you survive five yards or fifty, every hour is another battle against fatigue, doubt, and the temptation to quit. Don’t just watch the madness. Be part of it.
Crew setup and aid station
The designated grass field will serve as the crew setup area, opening at 3:00 PM.
Runners may bring personal nutrition, hydration, chairs, and other endurance-racing supplies. Keep all equipment within your designated area and leave access routes clear.
An event aid station will be located in the dirt area beside the grass field. Restrooms are available at the green-roofed building.

Limited spots are available for camping.
