Cactus Roulette Endurance Event

Lawrence, United States • 23-24 Jan 2027

Cactus Roulette Endurance Event

Cactus Roulette is a duration trail race with four time options: 24 hour, 12 hour Owl, 12 hour Lark, and 6 hour. Runners spin a roulette wheel before each loop to determine which of three loops they will run next. Each loop begins and ends at base camp.

Base camp is at Coneflower Campground in Clinton Lake State Park, Lawrence, Kansas. The event provides food, water, porta potties, heaters, access to personal drop bags, and space for personal tents with priority given to 24 hour racers. Live results are posted on monitors at base camp.

Course loops are run counter clockwise and color coded to match the roulette wheel. Separate starting mats are used for each loop so runners register each lap.

  • Swim Beach (Blue): technical trail, 3.6 miles, 253 ft elevation
  • Cactus Ridge (Green): technical trail, 2.6 miles, 239 ft elevation
  • Bunker Hill (Red): cross country field, 1.9 miles, 150 ft elevation

Every starter receives a completion award. Awards are given in male, female, and nonbinary categories for each time option. First place 24 hour finishers can earn a cash award of $250 with a minimum 100 mile requirement. Runners who complete 100 or more miles in 24 hours receive custom belt buckles mailed after the race. Unique SWAG is provided per time block and is guaranteed for registrations before January 9, 2027. The Cactus Roulette Blanket is available for purchase. Photos are provided by Mile 90.

Pacer rules allow pacers for 24 hour runners while no pacers are allowed for 6 and 12 hour runners. Each time block is capped at 50 runners. Littering on course may result in disqualification. If trails are unsafe, an alternate course may be provided. In the event of postponement or cancellation for reasons beyond organizer control, refunds will not be made but race packets may be distributed later or possibly mailed. All vehicles in the park must display a daily or yearly parking permit obtained at the park kiosk or the campground 3 self pay station.

The Joy Hawk Addendum allows linked teams of up to five racers to spin and run together as a team, share awards if they place, and be recognized if multiple linked teams run within a time block. Visit the organization's website for the most recent information.
