Folsom Lake Sweetwater Trail Run : Folsom Lake State Recreation Area

This event takes place at the Salmon Falls Parking Lot in Folsom Lake State Recreation Area, El Dorado Hills, CA. The trails are about 95% single-track and 5% dirt road, largely following the South Side Trail along Folsom Lake. The course passes through oak trees and grassy sections and includes gently rolling hills and some technical stretches.

Distances offered:

  • Kids Run (19 ft. ascent)
  • 1 Mile (114 ft. ascent)
  • 5K (259 ft. ascent)
  • 10K (734 ft. ascent)
  • 9 Mile (990 ft. ascent)
  • Half Marathon (1,555 ft. ascent)
  • 30K (2,106 ft. ascent)
  • Trail Marathon (3,001 ft. ascent)
  • 50K (3,356 ft. ascent)

Courses are out-and-back routes marked with ribbons, signs, and gypsum. There is a creek crossing that may cause wet feet and slippery rocks; an alternate route that avoids the creek may be used in inclement weather. Toilets are available at the start/finish and at aid stations on course. Multiple aid stations and water stops are provided; some aid stations have cutoffs and the event enforces a 9-hour overall time limit. Drop bags can be checked at registration for delivery to specified aid stations; participants are advised not to place electronics or valuables in drop bags. Dogs are not permitted on the course due to narrow single-track sections and participant volume. Volunteers are used to staff aid stations and assisting volunteers receive a future race credit.
