Black Hills 100 : Sturgis, South Dakota
The Black Hills 100 event weekend offers multiple trail distances centered on Sturgis City Park and the Centennial Trail (Trail #89). Distances contested are:
- 100 Mile (reported closer to 108 miles) out-and-back on the Centennial and Deerfield trails.

- 50K starts near the Dalton Lake trailhead and follows the Centennial to Sturgis.
- 30K starts on Runkle Road above Elk Creek and joins the Centennial to finish in Sturgis.
The 100 mile course begins and ends at City Park in Sturgis.
