Black Hills 100 Sturgis, SD

The event is a multi distance trail running weekend in Sturgis, South Dakota on June 25 to June 26, 2027. Distances offered include 100 Miler, 50 Miler, 50K, and 30K.

The 100 Miler course is described as closer to 108 miles and runs from City Park in Sturgis out along the Fort Meade bike path onto the Centennial Trail Trail 89. The route is mostly singletrack with short sections of old logging roads and a 13 mile stretch of ATV trail; the first and last mile are on paved bike path and the rest is dirt. The Deerfield Trail Trail 40 provides the final approach to the Silver City halfway point. The 100 Miler uses eight aid stations, seven of which are visited twice, and allows drop bags at Elk Creek (miles 19 and 87), Dalton Lake (32 and 74) and Silver City (53).

The 50 Miler follows the back half of the 100 Miler from Silver City to Sturgis and lists seven aid stations with drop bags at Dalton Lake and Elk Creek. The 50K and 30K start nearer Dalton Lake and Runkle Road respectively; the 50K has four aid stations and the 30K has three. Buses transport runners from Sturgis to the respective starts.

All events finish at Sturgis City Park adjacent to Woodle Field. The races are held under special use permit with the US Forest Service and the Bureau of Land Management; participants are asked to be courteous to the trails.
