Folsom Lake Sweetwater Trail Run

The event takes place on Saturday, January 23, 2027 at the Salmon Falls Parking Lot in Folsom Lake State Recreation Area, El Dorado Hills, CA. Multiple race distances are offered on primarily single-track trails that run along the south side of Folsom Lake through oak trees and Sierra foothill scenery.

Most of the course is single-track with gently rolling hills; small sections are on wider dirt road or pavement. Courses are out-and-back and are marked with colored ribbons, signs, and gypsum on the ground. Several distances include multiple aid stations and water stops, and toilets are available at the start/finish and at aid stations along the routes. There is a creek crossing on the Sweetwater trail; runners should expect wet feet and slippery rocks at that location. Drop bags may be collected and delivered to designated aid stations and returned to the finish area. Dogs are not permitted on the course due to narrow trail sections and participant volume. Parking on site is metered with a vehicle fee and overflow parking options are noted near the start area. Visit the organization's website for the most recent information.
