Embrace the ultimate test of endurance at the Earth Day Buckle Mania, set for April 24, 2026, in scenic Abilene, Kansas. This premier timed race offers challenging 48-hour, 24-hour, and 12-hour options, inviting runners to push their limits on a meticulously designed course. The race unfolds on a 1.8228-mile certified, paved, and mostly shaded loop, winding through a beautiful private park. With a flat to nearly flat elevation profile, the course is known for being fast and runner-friendly, making it ideal for both seasoned ultrarunners and those looking to achieve new distance milestones. Typical race day conditions in late April offer comfortable highs around 72°F and lows around 46°F, with a minimal 15% chance of precipitation.

What truly sets Earth Day Buckle Mania apart is its namesake: the chance to earn multiple buckles. Participants are awarded a unique buckle for every significant distance milestone achieved—50K, 50 Mile, 100K, 100 Mile, 150 Mile, and even 200 Mile—allowing dedicated runners to collect up to six distinct awards. Directed by veteran ultrarunner Will Sprouse and his wife Carrie, the event has a strong reputation for being a "first-class" experience, with runners consistently praising the supportive atmosphere and comprehensive organization.

The race provides exceptional runner support, including complimentary lodging and heated showers for registered runners, with options for crew and family at the start/finish area located at 1943 Indy Road. Aid stations are well-stocked, offering "real food" around the clock, described by past participants as some of the "best aid station food" available. Pacers are permitted after 12 hours to help runners through the longer endeavors. The looped course fosters immense camaraderie, as runners continually see and encourage one another, creating a uniquely supportive environment for tackling extreme distances.
