Rocky Ridge

Rocky Ridge is a trail running event held on 19 September 2026 in Las Trampas Wilderness, with the event address listed as 18012 Bollinger Canyon Rd, San Ramon, CA 94583, USA. Routes run on singletrack and fire roads within the wilderness area and include ridge sections and viewpoints.

Distances offered:

  • 5K: 3.1 Miles
  • 10K: 6.21 Miles
  • Half marathon: 13.73 Miles
  • Virtual Runner: virtual race option

The 5K includes one sustained climb. The 10K climbs higher to reach the Rocky Ridge Trail before descending to the finish. The half marathon follows a large figure 8 that travels up and out of the valley, crosses to the east side, returns, then ascends to the Rocky Ridge Trail before the finish. The event notes that many participants will walk portions of the courses; walkers and hikers are welcome. A virtual race option is available for those not on site.

Registration windows and fees are provided by the organizer for each entry category. The event focuses on trail terrain and elevation changes rather than flat road running. Visit the organization's website for the most recent information.
