Black Hills 100
The Black Hills 100 is a challenging ultramarathon held on the Centennial Trail (Trail #89) in the northern Black Hills of South Dakota. Featuring over 16,000 feet of elevation gain for the 100M event, the race follows an out and back course, beginning and ending in legendary Sturgis, SD. What the Black Hills lack in altitude, they make up for in relentless hills that offer a unique challenge compared to other western ultras.
