Course and event details

All races begin and end at Quarry Lakes. The course uses the Western Pacific Trail, a route historically used in the 1800s to transport gravel. The 10K and half marathon routes extend along the Alameda Creek Trail. Trails are primarily dirt fire trails, with sections of gravel placed to prevent erosion and a short paved section. The event describes the overall profile as mostly-flat.

Registration fees vary by distance and by registration period, listed with Super Early, Early Bird, and Regular tiers. A remote runner option is available with separate pricing. The event provides results and free photos, and includes information about bib pick-up, shirts and awards, pace groups, and volunteering on its race information pages.
