Course and logistics
Most courses are out-and-back and are marked with ribbons, signs, and gypsum. The trails are about 95% single-track and 5% dirt road, with gently rolling hills that run near Folsom Lake and through oak-covered terrain. The course includes some technical sections and a creek crossing that may result in wet feet; the rocks at that crossing can be slippery. Aid stations and toilets are available on course, and drop bags may be delivered to several aid stations. Parking in the Salmon Falls lot requires a self-pay fee of $10 per vehicle, with overflow and alternate parking locations noted. Volunteers support aid stations; volunteers receive a free future race entry. Visit the organization's website for the most recent information.
