About the Event

Discover a premier winter trail running festival for the whole family at the Folsom Lake Sweetwater Trail Run in El Dorado Hills, California, on Saturday, January 24, 2026. This exceptionally versatile event, organized by Troy's California Trail Runs, offers nine distances—from a kids' run and a 1-mile dash up to a challenging 50K—all starting from the scenic Salmon Falls Parking Lot at Folsom Lake. The course winds along the beautiful Sweetwater Trail, featuring 95% scenic single-track under a canopy of oak trees, with gentle rolling hills and stunning views of the lake and Sierra foothills. With a family-friendly, wave-start format, it's the perfect early-season goal for competitive ultra-runners, marathon trainers, and beginners alike. Every finisher receives a commemorative medal, and the well-marked, technically varied trails provide an ideal introduction to the sport or a serious test for seasoned athletes. The vibrant, inclusive atmosphere and professional organization make it a cornerstone event in the Northern California trail calendar. Prepare for a day of crisp winter running, incredible lake vistas, and community spirit on some of the region's most beloved and runnable trails.
