For runners in all three races, the event will follow an out-and-back route that starts and finishes just off Bollinger Canyon Road, near the park’s Little Hills Picnic Ranch and Las Trampas Stables areas. From there, runners in the half marathon make what is roughly a figure-8 style pair of loops through the park’s trails, heading first through the northern sections of the Las Trampas Wilderness along the Calaveras Ridge trail, the Madrone trail and the Sulphur Springs trail.
