The Morganzo 55: Double Nickels on the Grime
The Morganzo is the original, premier, grassroots, gravel bike route in the Gallatin Valley and Bozeman, MT. It is a beautiful fifty-five mile gravel and dirt route to be ridden entirely self-supported in the rolling foothills of the breathtaking Bridger Mountain Range. Whether you're looking to join the annual gathering of riders or ride the route yourself at your leisure peruse the website and get to know the Morganzo.
The 2025 gathering was Sept. 6th.
For past info check out the Ride Reports page. For future info about the annual gathering sign up for the email newsletter. Participants are to meet at the corner of Dry Creek Road and Theisen Roads just north of Belgrade, MT. First one done gets first crack at the cold ones.
Remember this is a self-supported route (aka no food and only minimal water available). It is on an un-marked course and there are no support vehicles. So come enjoy the annual group ride or head out and to explore it on your own but please do so prepared. Download the route .gpx file for your phone or GPS and take a look at the cue sheet.
Ride the Morganzo 55 Gravel Route Anytime
This is a great local or destination ride, and for those traveling it can easily be connected with a trip to historic Yellowstone National Park just ninety miles to the South. If you're a fan of a variety of dirt and gravel roads ranging from well-traveled and graded gravel to barely-there scratches of two track farm roads the Morganzo route is for you. Take a look at the route map and you'll see plenty of options for alternate route to shorten things up. And if you start to explore the outskirts you'll begin to see potential for additional mileage as well.
A Bit of History for this Long-Standing Tradition
The route was developed in 2012 by a humble cyclist looking to continue the tradition of the grassroots gravel races of his Midwest roots. Over the years the annual gathering, this website, and the tradition has been the passion project of a handful of individuals. The route lives on and this [almost] all-gravel route adjacent to Bozeman in Southwest Montana is sure to please everyone from beginner to diehard.
