Black Hills 100, live.

Out and back on the Centennial Trail from Sturgis

The Black Hills 100 starts at 10:00 am on Friday 25 June 2027 in Sturgis City Park, with the 50 mile, 50K and 30K on Saturday 26 June.

The Black Hills 100 is an ultramarathon on the Centennial Trail, Trail 89, in the northern Black Hills of South Dakota, organised by Dakota Endurance. The 2027 edition is on 25 and 26 June and offers four distances: 100 mile, 50 mile, 50K and 30K. Every course ends in Sturgis, and all distances share a final cutoff of 8:00 pm on Saturday.

The 100 mile starts at 10:00 am on Friday in Sturgis City Park and runs out to Silver City and back. The organisers are open that it is closer to 105 miles, with 16,779 feet of climbing and a 34 hour limit. The 50 mile starts at 6:00 am on Saturday at Silver City Community Hall and runs about 52.5 miles back to Sturgis in 14 hours. The 50K starts at 8:00 am from Dalton Lake with 3,800 feet of gain, and the 30K at 9:00 am from Runkle Road with 3,381 feet.

The trail mixes single track, rocky stretches and double track ATV trail, with as little pavement as possible. What the Black Hills lack in altitude they make up for in constant ups and downs. Late June brings average highs of 79°F, lows of 53°F and a chance of afternoon thunderstorms.

The top three women and men in the 100 mile receive a hand painted buffalo skull, the symbol on the Centennial Trail markers. Buses take point to point participants from Sturgis to their starts. Registration is open on Ultrasignup until 1 June 2027.

On Livebib you can follow a participant who chooses to share their own live position from the phone they carry. This is not the organiser's timing, and the official results come from the Black Hills 100.
