Western Pacific - Fremont, California
The Western Pacific event on March 28, 2026 takes place at Quarry Lakes Regional Recreation Area in Fremont, California. The event offers multiple distances:
- Half marathon
- 10K
- 5K
All races begin and end at Quarry Lakes. The 10K and half marathon routes extend along the Alameda Creek Trail. The course uses a section of the Western Pacific Trail, a corridor that was used in the 1800s to transport gravel for the western section of the Transcontinental Railroad.
Trails are primarily dirt fire roads with sections of gravel placed for erosion control and a short paved segment. The organizer describes the courses as mostly flat. A remote runner option is listed for participants who choose to run off site. Race materials note available results and free photos after the event.
The event information is presented by Brazen Racing and includes pages for race details such as bib pick up, course maps, shirts and awards, and frequently asked questions. Hikers, walkers and runners are welcomed on the course. Visit the organization's website for the most recent information.
