Run for Amma

The Run for Amma is a charitable trail event held at the Skyline Ridge Open Space Preserve in Los Gatos, California. Scheduled for Saturday, May 16, 2026, this year marks the 15th anniversary of the race. The event is unique in its philanthropic mission, as 100% of all registration proceeds are donated directly to the UCSF Julia Carnevale Lab to support cutting-edge cancer research and treatment developments.

The event offers three distinct distances catering to different skill levels, from technical ultra-running to a accessible 10K walk or run. Staggered start times ensure a smooth flow onto the trails.

The course winds through the scenic ridges of the Santa Cruz Mountains, offering expansive views and a mix of shaded forest and exposed ridge-line trails.

• - Challenge Level: The 50K and 30K courses are physically demanding with significant vertical gain, requiring steady climbing and descending skills.
• - Trail Conditions: Runners can expect well-maintained single-track and fire roads typical of the Midpeninsula Regional Open Space District.
• - Support: The race is supported by local running clubs, including the Stevens Creek Striders and Quicksilver Running Club, providing seasoned volunteers at various aid stations.

The Run for Amma attracts top-tier regional talent. Ryan Neely currently holds the standout course performance with a 3:44:16 finish in the 50K distance.

• - Registration: Online registration closes on Wednesday, May 13, 2026. Given the anniversary year and charitable nature, early signup is recommended.
• - Bib Pickup: Check-in and bib collection for the 50K and 30K distances take place on race morning between 6:30 AM and 7:15 AM.
• - Parking: All participants should park at the finish area located at the Skyline Ridge OSP equestrian lot.
• - Volunteering: The event relies heavily on the community for course marking, aid station staffing, and sweeping; opportunities are available for non-runners to participate.
