The Morganzo 55: Double Nickels on the Grime

A premier, grassroots, gravel bike route in the Gallatin Valley near Bozeman, MT.  Ride fifty-five miles of entirely self-supported gravel and dirt in the rolling foothills of the breathtaking Bridger Mountain Range.

The 2025 gathering will be Saturday, Sep. 6th.

Get your name on the email newsletter list.  We only send out a few messages per year so just go ahead and do it.  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.

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.

The route was developed in 2012 by a humble cyclist looking to continue the tradition of the grassroots gravel races of his Midwest roots.  This [almost] all-gravel route in rural SW Montana is sure to please everyone from beginner to diehard.
