Ray Miller 50/50

Ray Miller 50/50 takes place in Malibu, California, on December 5, 2026. Three trail distances go off in sequence on the Ray Miller side of the Santa Monica Mountains: the 50-mile at 6:00 AM, the 50K (31 miles) at 6:30 AM and the 30K (18.6 miles) at 7:00 AM. The 50-mile and 50K pairing is where the event gets its name.

Coastal mountain running here means long, sustained climbs and equally long descents, with ocean air that can be cool at dawn and warm by midday. Pace the climbs by effort and save your quads for the way down, because the descents are what usually decide the last hours. The 30K is a fine introduction to the terrain, the 50K a strong first ultra, and the 50-mile a race that rewards specific vertical training over general mileage.
