Nestled within the picturesque Sly Park Recreation Area, located near Pollock Pines in California’s El Dorado National Forest, the Trail Run at Sly Park offers runners an unforgettable experience through its lush pine forests and serene horse trails. This annual series of events takes place three times a year to showcase the park's changing beauty across different seasons. Participants can register on race day starting at 7:00 AM at the Event Center in the Scales (Equestrian Staging Area) within Sly Park Recreation Area, accessible via coordinates 38.712489, -120.553411 or through Google Maps directions available online. The race begins promptly at 8:00 AM with a trail briefing scheduled for 7:45 AM to ensure all runners are well-informed about the course and safety measures. The event features various distances including the 5k, 10k, an 8-mile route, half marathon, 17-mile challenge, full marathon, and a grueling 50k ultra-distance race. Each course is meticulously marked with ribbons, signs, and gypsum to guide runners through scenic trails that wind around Jenkinson Lake. The terrain ranges from gentle paths suitable for shorter distances like the 5k and 10k races to more challenging routes designed for endurance athletes tackling longer events such as the marathon or ultra-distance race. Aid stations will be strategically placed along each route, providing essential hydration and nutrition support throughout the event. Upon crossing the finish line, all participants receive a commemorative medal celebrating their achievement in this stunning natural setting.
