Acorn Creek Trail Run

The Acorn Creek Trail Run takes place on trails in the Gold Country foothills east of Folsom Lake. The event begins near the Acorn Creek Trailhead in Salmon Falls Ranch. The trailhead is privately owned and maintained by the American River Conservancy, a 501(c)(3) non-profit. The event is directed by Bizz Running Company and functions as a fundraiser; proceeds support trail work and maintenance in the Acorn Creek / Salmon Falls Ranch area.

Distances:

  • 10K (10.5K) one lap of the complete course
  • Half marathon two laps of the complete course

The course uses miles of single-track at Salmon Falls Ranch and includes smooth trail sections, creek crossings, climbs, and views. The Start/Finish line is on Main Street near the Boneyard Trail Junction and the cattle loading dock. The route combines an Orange loop and a Blue loop and visits named segments such as Highline Trail, Creek to Peak Trail, Folsom Lake Overlook, Chaparral Trail, Cowtown Trail, Cattle Chute Trail, Ranch Trail, and Sidewinder Trail. Half marathon runners pass the finish area between laps.

Parking at the Acorn Creek Trailhead is limited to 50 vehicles; 50 priority parking passes are offered as a first-come, first-served add-on. Additional parking is available at the Salmon Falls Sweetwater Trailhead but requires a Poppy Pass or a day use vehicle pass. A shuttle runs approximately every 15 minutes between that lot and the race venue. Carpooling is necessary due to limited parking.

Aid Station #1 sits at the Folsom Lake Overlook (mile 2.14 and 8.7) and Aid Station #2 is between the Blue and Orange loops (mile 5.26, 6.55, 11.81). Both provide fruit, sweet and salty snacks, gels, and water and electrolyte hydration.

The race is chip timed by Bizz Running Company. Bibs must be worn on the front outermost layer. Awards go to the top three overall finishers M and F for each distance and to the top winner in each 10-year age group. Runners receive a custom t-shirt and race medal; food and drinks are available at the finish and a coupon is provided for Gold Country Run + Sport.
