Cactus Roulette Endurance Event

Cactus Roulette Endurance Event

Cactus Roulette is a duration trail race held at Clinton Lake State Park in Lawrence, Kansas and organized by the Lawrence Trail Hawks. The event offers four time options: 24 hour, 12 hour Owl, 12 hour Lark, and 6 hour. Base camp is at Coneflower Campground and will provide food, water, porta potties, heaters, access to personal drop bags, and monitors with live results. Each time block is capped at 50 runners.

Course

Runners choose loops by spinning a roulette wheel before each loop; every loop begins and ends at base camp and all loops are run counter-clockwise. Each loop is color-coded and has its own starting mat.
