The Great Divide Mountain Bike Route (GDMBR), developed and mapped in 1997 by the Adventure Cycling Association, is approximately 2,700 miles long and is considered by many to be the birthplace of bike packing as a sport. The route follows the Continental Divide and is 90% off-pavement using high-quality dirt roads, gravel roads, trails, and a few short sections of unmaintained tracks. Bike packing the GDMBR requires only intermediate off-road mountain biking skills, but it is a painstaking test of endurance based on the sheer scale of the route, with over 200,000 feet (60,960 meters) of elevation gain and loss. Follow along with Dave Wilding who completed this ride the summer of 2022 with some days riding over 100 miles on dirt roads.
