San Lorenzo River Trail Run

The San Lorenzo River Trail Run, held in Santa Cruz, California, offers a scenic trail running experience through towering 1500-year-old Coastal Redwoods, stream canyons, meadows, and diverse forest landscapes. The event features multiple race distances including 10K, Half Marathon, 30K, Marathon, 50K, and a free Kid's Run for children six years and younger. Courses are well-marked with color-coded ribbons and include multiple crossings of the San Lorenzo River for longer distances.

The terrain consists mainly of single-track trails and dirt roads with significant elevation gains, making it a challenging and rewarding event. Aid stations provide hydration and snacks, and the race promotes environmental responsibility by being cupless. Visit the organization's website for the most recent information.
