Orange Curtain

The Orange Curtain Endurance Run, slated for June 20, 2026, in Cerritos, California, presents an exceptional opportunity for runners to test their limits across diverse distances, including 12HR, 50K, 26.2M (a Boston Qualifier Marathon), 6HR, 30K, and 10K, with options for 24HR and 100K. This home-grown, low-key event is celebrated for its predominantly flat and fast course, making it an ideal race for those aiming to achieve personal records or qualify for other prestigious ultramarathons. The route unfolds as a 10-kilometer out-and-back loop along a 5-kilometer segment of the San Gabriel River bike path, offering runners the unique choice of traversing either asphalt or an adjoining dirt path for approximately 90% of the distance. Typical race day conditions in June feature comfortable highs around 82F and lows of 63F, with a 0% chance of precipitation, providing favorable weather for endurance efforts.

Runners consistently laud the Orange Curtain for its outstanding support and community-focused atmosphere. The "awesome" aid stations, positioned strategically every 5 kilometers, are a highlight, well-stocked with a generous array of "typical ultra foods" such as fresh fruit, potatoes with salt, deviled eggs, and various sodas. Participants can also conveniently access their drop bags at the start line every 10 kilometers. While the repetitive nature of the loops can be a mental challenge, it simultaneously ensures consistent access to hydration and nutrition, fostering a highly supportive and welcoming ultra-running community. The race is known for its experienced ultra-runner organizers who are dedicated to providing everything participants need for a successful and memorable event.

The course, starting near the San Gabriel River Mid Trail at the South Street underpass, offers a pleasant, if subtle, scenic backdrop including views of local parks and occasional glimpses of ducks and egrets along the artificially channeled river. With free parking readily available, the Orange Curtain Endurance Run is perfectly set for an engaging and rewarding experience for runners of all distances in Southern California.
