Trailquake 2026

Om Run was launched in 2009 to bring the Bay Area Chinmaya Mission Family together. It is a fun filled day of outdoor activities for people of all ages. Om Run hosts more than 2000 people annually. It is the largest community building event organized by CMSJ. Om Run has evolved into a unique running event, in that, the focus is on community building with attractions such as pony rides, inflatable games, music and food along with a 5K, 10K and a 1/2 marathon race. Beautiful Vasona Park has breathtaking vistas and has hosted Om Run for the past several years.

The Splash and Dash Race is an aquathon consisting of a 1.5km (1-mile) swim and a 5km (3.2-mile) run.

It is a fun, community-focused, grassroots event. There are timing chips; the transition is not fenced in with guards; and spectators, kids, and dogs are encouraged. The swim is in Stevens Creek Reservoir, right outside of Cupertino, CA. The run is on the Stevens Creek Canyon park trails. It is a great way to get intense training in two disciplines or to get open-water swimming practice.

Sanborn County Park is home to well-groomed but steep and difficult trails, which makes for a challenging for runners of all abilities. Situated on the eastern slopes of the Santa Cruz Mountains and home to giant coastal redwood groves, the park is shaded and relatively temperate even in the hotter months, making it a local favorite for hikers, runners, and mountain bikers. Racers can expect big climbs and descents with good footing on flowy singletrack trails through dense forest.

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.

Race Start Times

The half marathon will start at 8:30 am, the 10K at 8:45 am and the 5K at 9:00 am. There will also be a "Hiker Division" start (for half marathon participants planning to take more than 3.5 hours) at 7:30 am.

Walkers/hikers and runners of all levels are welcome!
