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 best, this race is for you! We are excited to continue our partnership with the City of Folsom as our start line and hospitality host.

Due to permit capacity allowance, we look forward to staging AR25 in 2022.

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 Finisher's Athleisure Lightweight Pull Over Embroidered Hoody and classic AR50 medallion. After the finish, enjoy our post race festivities and celebratory post race eats, homemade divine dessert and refreshing beverages!!

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

Updates - March 24, 2021

As near as we can tell, the American River 50 was the first high-profile ultra forced to cancel when the pandemic began wreaking havoc in April last year. Cancelations were not yet commonplace, and it was a bruising experience for the runners and our organization. But we're all about endurance, aren't we? Head down, grind it out, right?

At 6:00am on Saturday, May 8th, 2021, the American River 50 Mile Endurance Run will return, and we hope to see you there.

We're back. And we have cookies/brownies!!
