Course and Transportation



Course Description

American River 50 Mile Endurance Run begins at beautiful Folsom Point, at Folsom Lake State Recreation Area in the Sierra-Nevada Foothills. With Folsom Lake as the sparkling backdrop you'll traverse through oak woodland and meadows, over bridges and creeks, up and down switchbacks and along the most spectacular trails in the area.

Runners will begin their 50 mile journey on single track trails and return to Folsom Point. Due to a multiple year BLM project (Folsom Dam Raise Mormon Island Auxiliary project) we are unable to use the first 7 miles of our original AR50 course. The 7 mile “add on” will occur in Auburn instead. Runners will head up the hill and then turn left to run a loop in the park before proceeding from Folsom Point parking lot up another hill and proceed past the park kiosk. At East Natoma Street runners turn right and continue west to the Folsom Lake Crossing.

The course then heads South on the American River Parkway past the historic Walker and Rainbow Bridges. Runners then turn right onto the Lake Natoma Crossing Bridge access path. After crossing Lake Natoma, the course remains on the south side of Lake Natoma on the American River Parkway through Willow Creek (Aid Station #1) and then to the Sacramento State University Aquatic Center. After the Aquatic Center, the course traverses across the Hazel Street Bridge, and climbs steeply to the top of the Hazel Bluffs, rewarding runners with expansive views of the surrounding landscape. Afterward, the trail winds along the scenic Middle Ridge Trail, eventually winding through the scenic Shadow Glenn horse stable area, blending challenging climbs with quiet picturesque sections.

The course then re-connects with the American River Bike Trail just before the Black Miners Bar Aid Station (Aid Station #2). Runners then stay on the American River Bike Trail until Beal’s Point (Aid Station #3).

The American River 25 event, which starts at 7 A.M. will start at Beal's Point and follows the second half of the AR50 course. *** NO PACERS ALLOWED FOR AR25 ***

After reaching Beal's Point, runners will enjoy single track trails and head north on the path worn by gold miners in search of riches: The Pioneer Express Trail that begins near the entrance of the Granite Bay State Park. Runners will cross the entrance road to the park and continue the Pioneer Express Trail to the Granite Bay Horse Assembly area (Aid Station #4). Stock up here! The distance to the next aid station is 6.5 miles. *** NO PACERS ALLOWED FOR AR25 ***

After exiting the Horse Assembly, the route continues north toward Twin Rocks Rd. The course continues the Pioneer Express Trail just above the Beek’s Bight parking lot and continues along the North Fork of the American River to Buzzards Cove, Horseshoe Bar (Aid Station #5) and Rattlesnake Bar (Aid Station #6). No, we aren't talking about stopping at local pubs, but rather passing by the sand bars where miners would pan gold… so enjoy the aid stations! The route then continues along the river to the Power Plant, Avery's Pond and Dowdin's Post (Aid Station #7).

The American River 10 Mile Endurance Run will start at Rattlesnake Bar (but not the aid station, about 1 mile before the aid station)! The AR10 is a point-to-point race beginning at Rattlesnake Bar at 9:00 A.M. The course will take runners from Rattlesnake Bar to Overlook Park. The course features single track technical trails with a mix of ups and downs. You will experience breath taking views of the American River and spring flowers. The course features 2 aid stations; Dowdin’s Post (Mile ~4) and Last Gasp (Mile ~7.5). We highly recommend you carry 2 bottles or use a hydration pack.*** NO PACERS ALLOWED FOR AR10 ***

After leaving Dowdin's Post, the trail winds its way to the infamous "Dam Wall." Runners will take a deep breath before climbing up to the “Party at Last Gasp” (Aid station #8). Leaving the Last Gasp aid station, the course climbs steadily on a paved road for 2.4 miles before reaching the back of the Overlook, where runners transition onto the scenic Overlook Trail. From there, the course connects to the legendary Western States Trail, leading to Murphy’s Gate, the final aid station (Aid station #9). After a quick refuel, runners will retrace their steps along the same trails, making their way back to the Overlook for an exhilarating 50-mile finish.

No trekking poles for participants or pacers, no dogs, no bikes, no horses.

Official Course Cut off is 14 hours
