The Black Hills 100, set in the iconic motorcycle town of Sturgis, South Dakota, offers an unforgettable trail running experience across multiple distances: 100M, 50M, 50K, and 30K. Kicking off on June 26-27, 2026, with the 100M race starting Friday, runners will tackle portions of the renowned Centennial Trail (#89) and Deerfield Trail (#40), navigating a challenging course that, for the 100-mile distance, boasts over 16,000 feet of elevation gain. This isn't your typical high-altitude mountain race; instead, the Black Hills deliver a unique challenge with "relentless" and numerous smaller climbs that truly test a runner's mettle, earning it a reputation as one of the toughest ultramarathons in the West.

The course, which for the 100M distance is actually closer to 108 miles, begins and ends at Sturgis City Park, taking runners through stunning green scenery, winding singletrack, old logging roads, and even a section of ATV trail. Expect diverse terrain with flowing sections, rocky patches, and high overlooks providing breathtaking views. Aid stations are strategically placed along the route, with the 100M offering drop bag access at Elk Creek, Dalton Lake, and Silver City, ensuring support on your journey. Typical race day conditions in late June bring highs around 84°F and lows around 56°F, with a 12% chance of precipitation, so prepare for varied conditions.

Beyond the immense challenge, the Black Hills 100 rewards finishers with unique accolades, including hand-painted buffalo skulls for top 100M finishers by a local Native American artist. For those who conquer all four distances over time, the esteemed "Man/Woman in Black" skull awaits. This race isn't just a run; it's an immersive journey through South Dakota's rugged beauty, demanding endurance and resilience from start to finish.
