BackBone Grande - Invitation & Offer

The BackBone Grande is a unique 421 mile bikepacking route across the State of South Dakota along the spine of the Black Hills. I designed this route specifically for a Great Divide type of bikepacking experience that showcases the best of our Black Hills and surrounding prairie. 

Three years later, I added the BackBone Double Grande, a 481 mile bikepacking route that connects the northern terminus and the southern terminus of the Grande to create a grand 902 mile bikepacking loop.

For a series of posts introducing these routes, including digital maps, images, and a series of posts of the first through-ride of the Grande, go to the Black Hills Grande & Double Grande Page.

If you have any questions, ask. If you're thinking of venturing out here, let me know. I'm happy to help.

Here's an offer. Ride the BackBone Grande and/or the Double Grande, any or all of them, and send me a picture and story. I'll send you a BackBone Grande sticker.

As others have noted, it doesn't say "Black Hills," or anything about bikepacking, or even cycling.

Nope. If you know, you know.

BackBone Double Grande - Elk Mountain Bypass

The BackBone Grande has Trail #1 for its one insanely difficult, Great Divide worthy climb. See, Trail #1. The Elk Mountain Lookout climb is that for the BackBone Double Grande.

If you seek a Great Divide type of experience, or a preparing to ride the Great Divide, the Elk Mountain Lookout climb may be for you. Otherwise, bypass it.

You've been warned.

At about Mile 377 of the Double Grande, the climb to Elk Mountain Lookout starts on a decent gravel road that passes a few residences, but soon turns to an old USFS two track that is closed to motorized vehicles. From there it climbs steeply on loose, rocky two track, gaining 1,128' over 5.3 miles, with a max gradient of 19.6%, according to RideWithGPS. Count on some serious pushing.

The climb up Elk Mountain Lookout rewards with stunning, drop-off the earth views, especially from the Lookout Tower. The descent, while on a more civilized USFS Secondary Road, is steep and curvy before finally bottoming out at Dewey Road (USFS Primary Road 769). This stretch is challenging and demands attention, ability, and judgement. It's not for everyone.

To bypass this beast, do not turn off U.S. Highway 16 at Mile 377, but simply continue on Highway 16 another mile to Dewey Road. Ride south on Dewey Road for about 3 miles to reconnect with the BackBone Double Grande Main Route at its Mile 389. Easy-peasy.

This 4 mile/260' gain bypass of the Elk Mountain Lookout adds a mile of highway pavement and 3 miles of USFS Primary gravel road, while subtracting about 12 miles/1,200' gain on USFS Low Standard and rougher roads. In other words, the bypass is a leisurely cruise on some pavement and good county gravel, instead of a beastly climb, crazy views, and a focused descent. 

The Main Route is a Great Divide worthy challenge for the experienced bikepacker. The Elk Mountain Bypass is a solid alternative.

Your call.

Introducing The BackBone Double Grande

The Black Hills BackBone Double Grande.

A new rough road bikepacking route that winds from the North Dakota/South Dakota border to Camp Crook, cuts across the southeastern corner of Montana, and climbs into northeastern Wyoming to Devil's Tower National Monument. It then climbs higher into the Bear Lodge Mountains, drops into Sundance, re-enters the Black Hills zig-zagging along the barely populated Wyoming/South Dakota border, climbs to Lookout Towers atop Warren Peak, Cement Ridge, Flag Mountain, and Elk Mountain, dives into the canyons of the far southwestern reaches of the Black Hills, and descends onto grasslands streaking to the South Dakota/Nebraska border.

The BackBone Double Grande is 481 miles of remote, rough road bikepacking, with very few re-supply opportunities, limited water sources, and practically no cell service for many, many miles. The "roads" include USFS Primary, Secondary, and Low Standard Roads, roads closed to motorized traffic, abandoned roads, trails, and lesser paths. There's very little pavement. Note that there is almost 30,000' of elevation gain, mostly on rougher forest service roads. For me, this is a route for a mountain bike with mountain bike gearing and  2.2" or wider tires.

More details ahead later this year, with section-by-section reports and images. For now, here's a digital map. BackBone Double Grande.

The BackBone Double Grande is for experienced, self-sufficient, well-prepared bikepackers. Not for the casual rider. Not for the toe-dipper. Not for the uninitiated.

The real magic of the BackBone Double Grande emerges when connecting it to the BackBone Grande.

The Double Grande start at the North Dakota/South Dakota border is the northern terminus of the BackBone Grande. The Double Grande finish at the Nebraska/South Dakota border is the southern terminus of the BackBone Grande.

Combining the 481 mile BackBone Double Grande with the 421 mile BackBone Grande forms one big, bad, remote road bikepacking experience through the best of our Black Hills and surrounding prairie. Here's a Collection of digital maps for the BackBone Grande, Double Grande, and Alternatives. BackBone Grande & Double Grande + Alternatives.

This has been a long time coming.

 

I created my original BackBone Grande route specifically for bikepacking the best rough roads across the State of South Dakota along the spine of the Black Hills and across the surrounding prairie. See, Introducing the BackBone Grande. By its very nature, it was a point-to-point route, like its inspiration, the Great Divide Mountain Bike Route. See, Yes, Point-to-Point.

Almost immediately after publishing the BackBone Grande in January 2023, however, I began receiving requests for a return route, i.e., to create a loop from the finish at the North Dakota border back to the start at the Nebraska border. But I just wanted to ride the route, not in bits and pieces over years, but as a through-ride accumulating miles, challenges, thoughts, and emotions as continuously presented. I needed a single, long through-ride to fully experience the BackBone Grande.

So, in June 2023, I rode the first through-ride of the BackBone Grande with bikepacking buddy Paul Brasby. See, BackBone Grande - The First Through-Ride. I loved it. Afterward, I tweaked a couple of stretches and later added more amazing tracks through Buffalo Gap National Grasslands. See, e.g., The Challenge of Buffalo Gap National Grasslands. Eventually, I created a Page compiling all my BackBone Grande posts to help others intrigued by the possibility of such an experience. BackBone Grande Page.

just north of Jewel Cave National Monument. Part of the BackBone Double Grande.

With the BackBone Grande completed in every way, I finally started to visualize a return route, which I decided to call the "BackBone Double Grande." Unlike the BackBone Grande, this return route would not be limited to the State of South Dakota, so I looked westward into a sliver of Montana and chunks of Wyoming. And I decided to amp up the logistical challenges by venturing more remote than the BackBone Grande. This would not be "more of the same," but a markedly different experience, not for the uninitiated. See, BackBone Double Grande - A Work In Progress.

Since late Summer of 2023, I researched possible routes by scouring digital and paper maps, reviewing reports and images of prior rides by myself and others, and, most importantly, physically scouting possibilities by Jeep and by Jones. The bikepacking options out here are an outright embarrassment of riches.

All that takes time. For example, just to drive highways to the Nebraska border near Ardmore is a solid 2 hours one-way from Rapid City. The North Dakota border start is about 3 hours one-way. Areas further west and more remote take longer.

But the real time sink is scouting as many roads and near-roads as possible to select and connect the very best for the intended route. With virtually unlimited mapped and unmapped tracks spider-webbing the public lands of the Black Hills National Forest, that can be a never-ending task. Out in the prairie, with a high percentage of land privately owned, the options of public roads and paths shrink dramatically. But it all still takes time.

So, since 2023, I have continued to piece together a BackBone Double Grande route. Sometimes, all roads that I follow lead to nothing particularly unique or even to dead-ends. Sometimes, scouting for other routes, like the new BackBone Buffet or the next Black Hills Bounty, leads me to roads and trails that I am compelled to include on the Double Grande. See, e.g., Red Bird Canyon.

Now, three years after introducing the BackBone Grande bikepacking route, I'm finally introducing the BackBone Double Grande.

It's all out there.

Time for a through-ride.
