Run Crazy Horse Marathon

Custer, United States of America · Sunday 4 October 2026

Official WebsiteRoadFull Marathon

The Black Hills of South Dakota offer runners a rare combination of natural beauty and historical significance. This region, crowned by the colossal Crazy Horse Memorial carving into the mountainside, provides a dramatic backdrop for distance running. The landscape here is rugged and scenic in ways that most marathons simply cannot match, with dense pine forests, exposed ridgelines, and sweeping vistas across the South Dakota plateau. Running through the Black Hills means tackling genuine mountain terrain rather than the manicured park loops or urban courses common to most marathons. The Crazy Horse Marathon starts right in the shadow of the memorial itself before winding through the region's moderately hilly trail network. The course climbs steadily throughout, with nearly 250 meters of elevation gain distributed across the 42.2 kilometers, meaning there's no easy section where you can coast. The terrain itself ranges between 1522 and 1849 meters above sea level, so runners will be working at altitude for the entire race. Finishing in Hill City puts runners at the heart of the Black Hills rather than back where they started, so the route genuinely explores the region rather than looping back on itself. Race day takes place in early October 2026, which puts runners in what is typically pleasant fall weather for the Black Hills. The marathon is in its 16th year, suggesting a well-organized event with established logistics for packet pickup, shuttle services, and the usual pre-race expo. Runners should expect a serious mountain marathon experience here, not a fast course or a leisurely Sunday run. The combination of elevation, trail surface, and rolling terrain means this is a race that demands respect and proper hill training in the months beforehand.
