American River 50 Mile Endurance Run. This 50-mile endurance race offers runners a chance to view picturesque scenery of Folsom Lake, Lake Natoma, the American River Parkway, and the American River Bike Trail.

Music, motivational quote signs, superb aid stations and encouraging volunteers will inspire you all the way to Auburn. At the finish line, you will be awarded your one of a kind finisher's jacket and classic AR50 medallion. After the finish, enjoy our post race festivities and food at Joe's Café AND our celebratory beer garden!
