About this race
Event Overview
- Date: September 19, 2026
- Location: 18012 Bollinger Canyon Rd, San Ramon, CA
- Event URL: Rocky Ridge Race
Race Descriptions
- Half Marathon: This is the race your momma warned you about! The half marathon cannot be described as "flat and fast" or "good for beginners" or with any other nice phrase. In fact, the phrases most commonly used to describe it would be unprintable.
- Experience: But...once you finish the course, you will have experienced trails and seen views that few others ever will.
- Bragging Rights: And you will have a lifetime of bragging rights!
Other Race Options
- 10K and 5K: The 10K and 5K are not quite as intense as the half marathon, but don't worry, those runners will also be challenged with some hills.
- Vistas: Participants will be rewarded with some rarely-seen vistas.
Join Us
- Call to Action: If you are one of those brave souls ready to face either victory occasion and face this beast, come join us on September 19, 2026!
