RACE OVERVIEW

The Black Hills 100 is a challenging ultramarathon held on the Centennial Trail (Trail #89) in the northern Black Hills of South Dakota. Featuring over 16,000 feet of elevation gain for the 100M event, the race follows an out and back course, beginning and ending in legendary Sturgis, SD. What the Black Hills lack in altitude, they make up for in relentless hills that offer a unique challenge compared to other western ultras.

Course Overview

  • Surface: Dirt, rocks, single-track trail, double-track ATV trail, as little pavement as possible.
  • Course: Centennial Trail (Trail #89) and Deerfield Trail (Trail #40)
  • Elevation Profile: Up. Then down. Then up again. Repeat.
  • Host Town: Sturgis, South Dakota
  • Average Late June Weather: High of 79 degrees, low of 53 degrees, chance of afternoon thunderstorms.

Fun Facts

  • The Centennial Trail was created in 1989 in recognition of South Dakota’s centennial, hence the trail’s name and number. Originally a mixture of single-track trail and old logging roads, over the past 30 years the trail has been rerouted numerous times to create a mostly single-track route. At 111+ miles, it is the longest trail in South Dakota.
  • The top three men and women in the 100 mile race receive a hand painted buffalo skull designed by a local Native American artist. Runners can also earn the special Man/Woman in Black skull by completing each of the four distances we offer (30K, 50K, 50M and 100M). The buffalo skull is also the symbol that appears on Centennial Trail markers and is the inspiration for our race logo.
  • Sturgis, our host town, is home of the world-famous Sturgis Motorcycle Rally, which draws upwards of half a million bikers each August.

In a normal year, we would’ve spent today cleaning up after the race, drinking a few beers, telling war stories, and getting caught up on sleep. Instead it was spent doing....well, pretty much nothing. Felt weird.

If you were registered for this year’s race, you should be getting an email inviting you to register for the 2021 event. You should also have a credit applied to your Ultrasignup account, so that when you go to register for 2021 you don’t get charged again. That’s a lot of shoulds, so if something doesn’t work out, send us a message and we’ll get it sorted out. This is our first time dealing with a cancellation so this is all new territory. The rollover credits are good until Sept. 1st, at which time we’ll open things up to waitlisters.

June 25, 2021 is less than a year away. Better start training!

Did a fastpack of the Centennial instead. 3 days 7 hours.

I’m so excited for 2021 Melissa Mc!! My bags are already packed

Logged a few miles on Centennial trail yesterday a little further south. Couldn’t let a planned vacation weekend go to waste. See you next year.

Impressive stuff Jon Schneider, 100 miles in the books!! ... See MoreSee Less

24 hours, 25 minutes, with only a few points of aid besides stashing water/food at trailheads 👍🏼

Great job

No way!!! Way to go!

If you’re heading out and about on the Centennial and curious about the creek crossings, they are definitely flowing but in a good refreshing kind of way as opposed to the raging torrent kind of way. Dog approved! ... See MoreSee Less

Me! I have some strong words for that top shale section...

I hiked it with the hubs!

Wow, I think Minnesota could use a really long run. Maybe we would feel better.

Weather looks too mild for a BH100 summit

Is this a virtual run?

Where is this?

I'd walk it...but NOT run it!!!

A deer antler

Corrugated Steel roofing

The totum stand with the race sponsor displays. Which was setup at the start/Finnish.

The finish arch frame

The seat must be encrusted with Black Hills gold, but you are asking about the frame. I believe it is made of cedar boards so that they will last for many pees, I mean, decades.

Looks a lot like one of the cattle water tanks near alkali.

Chris Stores old still.

The frame looks like 2x4’s. The siding is a different story.

Metal and wood! 2021 - 100 mile - on the house!!!

Two doors. One for each side, covered in corrugated metal.

The frame is old telephone/utility poles?

Our crushed hopes and dreams?

Hmmmm Crooked Tree? No, I'm guessing it's made from a watering tank for the beef:)

Forest service tool cache?

Steel drill pipe

Frame made of sign posts?

Old wooden gun cabinet. That’s one fancy outhouse you got there.

Railroad tracks

Cattle water tank!

Telephone booth?

Square pipe

Something in Galena....🤔

Old pallets.

Looks like wood fence posts or old utility poles?

Coffin ⚰️😂
