Sycamore Canyon 2027

Sycamore Canyon hosts a trail race series in Goodman Ranch Sycamore Canyon Preserve, east of San Diego, featuring a 100K, 50K, and half marathon. The longer races are available solo or as four-person relays; the half marathon is a single-distance option. The event begins before sunrise: 100K solo runners start at 5:00 a.m., the 50K and relays at 6:00 a.m., and the half marathon at 7:00 a.m. Packet pickup opens at 4:30 a.m., with all participants required to be off course by 10:00 p.m. The 100K and 50K utilize a figure-eight lap course, accumulating approximately 1,400 feet of climbing per loop. The 50K covers 51 km with 5,600 feet of elevation gain, and the 100K spans 102 km with 11,200 feet of gain over eight laps. The upper portion of the figure eight is consistently run clockwise; the lower section reverses direction each lap, adding variety to the repeated loops. Solo 100K participants must have completed a prior 50K-distance race or longer, and slower 100K runners may opt for an early start. In the relays, each 100K runner completes two 7.9-mile laps, while each 50K relay runner covers one lap, allowing teams to strategize runner rotation. The event, established in 2016, includes prize money.
