About the Race

This race is run on 95% single-track and 5% dirt road. The course primarily follows the South Side Trail. Very appealing single-track course, and great running with some technical sections. With gently rolling hills in El Dorado Hills, the trail parallels Folsom Lake and is covered by oak trees, lush green grass, and stunning scenery of the surrounding Sierra foothills.

Volunteers are needed to help with aid stations.
