American River Endurance Run

American River Endurance Runs is a three-race ultra series from Folsom to Auburn, California, along the scenic American River Parkway. The flagship AR50 has become the second-largest 50-mile race in the United States, attracting veterans and newcomers, with companion 25- and 10-mile events finishing in Auburn. The course showcases canyon and river scenery as runners traverse Northern California trails.

The atmosphere is festive and supportive, with music, motivational signs, ample aid stations, and volunteers guiding finishers. Rewards include a one-of-a-kind AR50 pullover hoodie and a classic finisher medal for all distances, plus post-race food and beverages.
