Organiser's description
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.
All courses include a mix of fire roads, single track and very small sections of paved trail. The half marathon and 10K include a climb up to the top of Sanborn Park. Smart runners will walk the hills and save their energy for the flats and downhills!
