American River has become the second largest 50 miler in the United States. The race attracts both veterans and novices alike. Whether you are attempting your first 50 miler or seeking a personal record, this race is for you! We are excited to partner with the City of Folsom as host to our new start line. We have also added a 25 miler event, starting in Beals Point. Two races, one scenic area!

The Race

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 Patagonia finisher's jacket and classic AR50 medallion. After the finish, enjoy our post race festivities and barbeque at Joe's Café.

Great Support

Thank you to our generous sponsors and heartfelt volunteers. Without their support, we could not stage these events.

Enjoy the Journey,
Julie Fingar
Race Director
