Hosted by Troy’s California Trail Runs, this compact late-November trail festival serves up long and short options—from a challenging 36-mile ultra down to community 10K/5K distances—on largely single-track terrain hugging the Folsom Lake area. Expect stony dirt paths, technical sections and sustained climbs/descents that reward careful pacing and offer big water views. Race day is a morning event with staggered starts and published course maps/GPX; organizers list standard time limits and aid/crew guidance on the event page.
