The Route

Download the cues sheets and map files here.

The Morganzo 55: Double Nickels on the Grime route can be ridden nearly all year ’round with the exception being times of heavy snow or immediately after a rain storm.  During these times some sections become “impassable when wet“.

Annually during mid-August the official Morganzo 55: Double Nickels on the Grime race/ride event is held that has drawn anywhere from six to 25 participants.  The exact day of the year is typically announced a number of months out and can be found here on this website or on other popular gravel grinding websites.  The official start point for the Double Nickels on the Grime race is the corner of Dry Creek Road and Theisen Roads just north of Belgrade, MT.

Cost for the event is free but donations are appreciated. There are no winners nor losers,  just first and last pick from the cooler of cold ones.
