Rocky Ridge 2026
Rocky Ridge 2026 is a trail running event on September 19, 2026, at Las Trampas Wilderness, Bollinger Canyon Road, San Ramon, California. The event includes multiple distance options and on-course terrain that the organizer describes as hilly and on trails with notable views.
Event distances:
- Half Marathon
- 10K
- 5K
The organizer notes the half marathon is not flat or fast and includes significant hills and trail sections. The 10K and 5K are described as less intense than the half marathon but still include hills and scenic vistas. The half marathon serves as the finale of the 2025/2026 Ultra Half Marathon Series; series participation is not required to enter this race.
There is a separate hiker start intended for walkers who expect the half marathon will take longer than about 3.5 to 4 hours. Remote runner options are available, including an international remote runner option for which remote packages are shipped via USPS. The event is associated with the East Bay Regional Parks Campership Program as a fundraising partner.
Registration is organized with tiered pricing periods and includes both local race entry options and remote participation choices. Visit the organization's website for the most recent information.
