Orange Curtain

The Orange Curtain Endurance Run takes place in Cerritos, California, featuring distances of 100K, 50K, 30K, marathon, 24-hour, 12-hour, 10K, and 6-hour events. The course is a mostly flat 10 km out-and-back loop along the San Gabriel River bike path, combining asphalt and dirt surfaces, repeated multiple times depending on the race distance. It is a Boston Marathon qualifier with USATF certification, known for being fast and beginner-friendly.

Aid stations are located every 5 km, and runners must bring their own hydration gear as the race is cup-less. The event offers a supportive atmosphere with experienced organizers and night-time pacers for safety. Visit the organization's website for the most recent information.
