Cactus Roulette Endurance Event

Cactus Roulette is a duration trail race hosted by the Lawrence Trail Hawks at Coneflower Campground, Clinton Lake State Park, Lawrence, Kansas. The event offers these time options:

  • 24 Hour
  • 12 Hour Owl (Saturday evening)
  • 12 Hour Lark (Sunday morning)
  • 6 Hour

Runners complete a series of loops that begin and end at base camp. Before each loop, competitors spin a roulette wheel to determine which loop they will run next. All loops are run counter-clockwise, color coded to match the roulette wheel, and have separate starting mats for lap counting. Live results are posted on monitors at base camp.

There are three distinct loops with varied terrain and elevation: a technical 3.6 mile loop with 253 ft elevation, a 2.6 mile technical loop with 239 ft elevation, and a 1.9 mile cross country loop with 150 ft elevation. Base camp provides food, water, porta potties, heaters, access to personal drop bags, and space for personal tents with priority given to 24 hour runners.

Awards and rules: every starter receives a completion award; awards are given in male, female, and nonbinary categories for each time option. 24 hour first place has a $250 cash award conditional on a minimum of 100 miles, and runners who reach 100 or more miles receive custom belt buckles mailed after the race. Each time block is capped at 50 runners. Pacers are allowed for the 24 hour division but not for the 6 or 12 hour divisions. Linked teams may spin and run as a unit and must run together for loops to count; linked teams cannot exceed five racers. Visit the organization's website for the most recent information.
