Heart of Cool Trail Run 2026

The Heart of Cool Trail Run takes place in Cool, California, a small Sierra Foothills town of approximately 4,000 residents. It provides 5K, 10K, and half marathon distances, all run on unpaved local trails. The race headquarters is located at 860 Cave Valley Road. This event occurs in the fall and began in 2016. It features a low-profile course: the start is at about 1,500 feet elevation, and the highest point reaches approximately 1,550 feet. The race is designed for families and trail runners alike, offering walk-friendly shorter distances and family pricing for the 5K and 10K. Paid child care is available for young children. Proceeds benefit youth programs within the Black Oak Mine Unified School District, supporting areas such as agriculture, engineering, and visual and performing arts. Additionally, some funds contribute to a Camp Taylor scholarship for a child with heart disease. Situated near Gold Rush historical areas, the run incorporates a local history theme alongside its Sierra Foothills trail setting.
