Folsom Lake Marina


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!

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.

Option – AR25

The course will start at Beale’s Point and will follow the AR50 course up to Auburn Overlook!! This event will start at 7AM, and there will be an option to take a bus in the morning from the Overlook down to Beale’s (however, there will not be a bus from the Overlook to Beale’s at the Finish). You will have the same time frame to finish the 25 miles, as AR50 does (must finish by 8PM).

Every 25 Miler runner will receive:

• Technical Running Shirt
• Goody Swag Bag
• AR25 Medallion (Finisher’s only)
• Post Race BBQ and Dessert Bar
• Outstanding Volunteer Support

The race begins at the Folsom Lake Marina at Brown’s Ravine. Runners will traverse the park road for 1 mile before hitting the majestic Brown’s Raving single track trails. Runners will make their way to Folsom Point, then along the Folsom Dam, across the Walker Bridge to the south side Lake Natoma before rejoining (our existing course) at the Nimbus Bluffs.

Upon descending from the Nimbus Bluffs, the course will re-connect with the bike trail and intermix with fire roads and single track trails through mile 22. From mile 22 to mile 27, the course re-joins the pavement. After reaching Beal’s Point, runners will enjoy single track trails for the duration of the run to Auburn. At mile 46, runners will climb the infamous “Dam Wall.” Runners will be greeted at the summit by the Last Gasp aid station with cheering enthusiasts. With 3 miles to go, motivational mile mark signs, will boost your spirits as you tackle the last climb and ice cold cokes will send you off on your victory mile to Auburn.


It all started with a conversation between Sally Edwards and Mo Livermore back in 1979. At that time, The American River Ride (horse race) started in Sacramento and finished in Auburn. When Mo described the venue and trails, Sally realized the course could be a challenging and beautiful 50-mile endurance run. And thus, a race was born. In 1980, nearly 200 runners toed the line at the Auburn Fair Grounds for the start of the inaugural AR50. Since 1982, the run has started in Sacramento. Over the years, a total of more than 10,800 runners have crossed the finish line.
