Event overview
Cactus Roulette is a duration trail race hosted by the Lawrence Trail Hawks at Coneflower Campground, Clinton Lake State Park in Lawrence, Kansas on January 24-25, 2026. The event offers four time options: 24 hour, 12 hour Owl (Saturday evening), 12 hour Lark (Sunday morning), and 6 hour. Before each loop, runners spin a roulette wheel to determine which loop they run next. Base camp will include food, water, porta potties, heaters, access to personal drop bags, and live result monitors.
Course
All three loops are run counter-clockwise, color-coded to match the roulette wheel, and begin and end at base camp. There are separate starting mats for each loop.
