The race

What this one is

The Black Hills 100 is run on the Centennial Trail (Trail #89) in the northern Black Hills of South Dakota, starting and finishing in Sturgis. It offers a 100 mile out and back, and a 50 mile, 50K and 30K that run point to point into Sturgis City Park. The trail is mostly singletrack, with rock, ATV double-track and as little pavement as possible, and the hills are relentless rather than high.

The Black Hills 100 was created and is directed by local trail and ultra runners who wanted to show off their favorite trail to the rest of the world. Since 2018 a runner who finishes all four distances (30K, 50K, 50M and 100M) earns the Man or Woman in Black buffalo skull.

I keep this catalog because the information is scattered and hard to trust. Telling you when it moves is the same job.
