About
San Diego 50 & Trail Runs is held in Escondido, California, on January 9, 2027. The 50-miler starts at 6:00 a.m., the trail marathon (26.2 miles) at 7:00, the half marathon (13.1 miles) at 8:00, and the 10-mile summit run, the 5-mile valley run and the stroller-friendly 5K all at 8:30. A relay and an untimed one-mile kids' race round out the program, on scenic trails including Raptor Ridge. The event is cupless, so bring your own hydration containers.
The organizers call the half a tough one, which is the right expectation for a trail course sharing a venue with a 50-miler: run it by effort and let the climbs take the time they take. The marathon and the ultra ask for long runs on rough ground and a rehearsed cupless setup rather than mileage alone. Beginners are genuinely catered for, though — the 5K takes strollers and the kids' mile is untimed — so a family can build the day around one person's long race.
