Anza Borrego Cuyamaca 50 Mile Run (50M) - Dec 5, 2026 | Julian, CA

The Anza Borrego Cuyamaca 50 Mile Run, affectionately known as ABC 50, offers an exhilarating point-to-point ultramarathon experience on December 5, 2026, originating in Julian, CA. This challenging 50-mile race, with approximately 5,564 feet of elevation gain and 8,179 feet of loss over 50.4 miles, takes runners on an unforgettable journey from the majestic mountains to the stark beauty of the desert, a unique characteristic that has quickly made it a San Diego classic. Beginning at the Sunrise Trailhead, the course quickly descends into Cuyamaca Rancho State Park, where runners will ascend both Cuyamaca and Stonewall Peaks, navigating a mix of singletrack and fire roads. The initial miles are often praised for their stunning, wooded scenery, but don't be fooled; the second half introduces more technical, rocky, and sandy trails, culminating in a steep descent down Oriflamme Canyon onto the desert floor. Typical race day conditions in early December bring crisp highs around 54°F and lows of 40°F, with a slight 13% chance of precipitation, making for ideal running weather as you traverse diverse landscapes.

Runners can expect exceptional support along the course, with "fabulous, beyond belief" aid stations strategically placed every 6-9 miles, many offering easy access for crew and family. Drop bags are available at Sweetwater (mile 12.7), Paso Picacho (mile 24.6), and Pedro Fages (mile 35.4) to assist with mid-race needs, including mandatory headlamps for those leaving Pedro Fages after 1:00 PM. The 14.5-hour cutoff provides ample time to complete the course, though intermediate cut-offs at Paso Picacho (7.5 hours) and Pedro Fages (10 hours) add to the strategic challenge.

The finish line awaits at Stagecoach Trails RV Resort & Campground in Shelter Valley, where a post-race meal, showers, and camping options provide a welcome respite after conquering this demanding route. A pre-race shuttle service from the finish to the start simplifies logistics for participants, allowing runners to focus solely on the incredible vistas and varied terrain that define the Anza Borrego Cuyamaca 50 Mile Run. This race is a true test of endurance and a celebration of Southern California's breathtaking wilderness.
