Orange Curtain Marathon

Running in Cerritos in June means preparing for heat and humidity typical of Southern California's early summer, so arrive acclimated and plan your hydration strategy carefully. The Orange Curtain Marathon offers a genuinely flat course with only gentle rolling sections and minimal elevation change, making it suitable for runners targeting a fast time or building confidence on a predictable terrain. At just 8 to 16 meters above sea level on a road surface, there are no surprises waiting to drain your legs, which means your fitness level should translate directly to your performance. The June timing is worth considering since the heat could be significant by race day, particularly if you're coming from a cooler climate, so train your heat tolerance alongside your mileage. Check the race website for specific details on aid station spacing and course support, as these logistics matter more on a warm day than the elevation profile alone.
