Prepare for an unforgettable trail adventure at the Rockin K, taking place on April 4, 2026, in the ruggedly beautiful Kanopolis Lake State Park, Ellsworth, KS. This challenging event offers a 50K, Marathon, 21-mile, and 4-mile distance, catering to a range of trail enthusiasts. Known as one of Kansas's oldest ultras, the Rockin K has earned a reputation for its demanding yet incredibly rewarding course through the unique Smoky Hills landscape. Runners will navigate four interconnected loop trails—Horsethief Canyon, Prairie Trail, Alum Creek, and Big Bluff—encountering a diverse terrain of rocky sections, sand, and significant elevation changes, including steep climbs and descents that are surprising for Kansas. Expect numerous water crossings, some of which can be waist-deep, adding to the excitement and ensuring wet feet for much of the journey. The stunning scenery, featuring sandstone bluffs, canyons, and marsh areas, provides a breathtaking backdrop to this mentally and physically engaging race.

The Rockin K is celebrated for its well-marked course and the exceptional support from its volunteers, creating a welcoming and fun atmosphere despite the tough conditions. Aid stations are strategically placed, with at least two well-stocked manned stations and additional water-only unmanned stations along the route, where hand sanitizer will be available. The race headquarters, start, and finish are conveniently located at the Corral Shelter area within the Rockin K campgrounds. Upon crossing the finish line, participants can look forward to a satisfying post-race meal of hamburgers and brats, with vegetarian options, and the iconic finisher's horseshoe award. Typical race day conditions in early April feature comfortable highs around 66°F and lows around 37°F, with a low chance of precipitation, though runners should be prepared for potential sun exposure and chilly mornings. The event is limited to 120 participants across all distances, fostering a close-knit community feel. This race truly embodies a "marathon that's really an ultra," offering a distinctive and memorable experience that runners often highly recommend.
