Read part I here: Full Circle on the Grand Loop: Part I – Trail Visions Ahead of Their Time
With the ambitious origins of the Grand Loop being shared in Part I of this series, let us now dive into the impact the route had on the evolution of bikepacking, and more specifically, bikepacking races. After all, the Grand Loop Race (GLR) was arguably the first of the modern bikepacking events and is responsible for creation and evolution of some of the most popular and longest-running mountain bike ultras in the United States – the Colorado Trail Race and the Arizona Trail 300. The Grand Loop was also the first long and particularly difficult off-road route to become a notable draw for bikepackers.
