Black Hills 100 - Sturgis, South Dakota
The Black Hills 100 is an ultramarathon held on the Centennial Trail in the northern Black Hills of South Dakota each June. The event is scheduled for June 25-26, 2027 and offers four distances: 100 Mile, 50 Mile, 50 Kilometer and 30 Kilometer. The 100 Mile is an out and back course; the other distances are point to point. Registration is currently open and closes June 1, 2027. A general cut-off time for all distances is 8 PM on Saturday, with individual cutoffs for each distance.
The course runs on Centennial Trail (Trail #89) and Deerfield Trail (Trail #40) with surfaces that include dirt, rocks, single track trail and double-track ATV trail, and as little pavement as possible. The event emphasizes repeated climbs and descents rather than sustained high altitude. The 100 Mile course reports 16,779 feet of elevation gain; other distances list both gain and loss figures. Late June weather averages a high near 79 degrees and a low near 53 degrees, with a chance of afternoon thunderstorms.
Awards include hand painted buffalo skulls for the top three men and women in the 100 Mile race, and a special Man or Woman in Black skull for athletes who complete all four distances. Visit the organization's website for the most recent information.
