Cheeseboro Canyon Trail Run

The Cheeseboro Canyon Trail Run, held in Cheeseboro National Park near Agoura, California, offers a variety of distances including a challenging 50k ultramarathon, a half-marathon, a 5k trail run, and a kids' 2k fun run. The course features diverse terrain with runnable ascents, winding singletracks, steep fire road climbs, and smooth descents. The 50k route extends beyond the canyon to include more serious climbs and scenic landscapes, making it tougher than it appears.

The event is known for its low-key, local atmosphere and high-quality production, concluding with a post-race festival featuring awards, food, and a beer garden. Visit the organization's website for the most recent information.
