Summit Rock 2026

RUN UNDER THE REDWOODS FOR A 5K, 10K OR HALF MARATHON! Come join us in the beautiful redwood groves of the Santa Cruz Mountains! Tucked away just outside Silicon Valley, Sanborn County Park features miles of single-track trails dappled with filtered light through lush canopy. Half Marathon and 10K runners will ascend to peaks offering spectacular views and all distances will include breathtaking single track trails. While experienced runners will enjoy the challenge and exploration of new territory, those new to the trails will also discover a whole new world of running where it is perfectly normal (and highly recommended!) to walk the hills and save your energy for the flat and downhill sections
