The Reservoir Dogs Trail Run is an October trail race held at San Pablo Reservoir, located near Orinda in the East Bay. All race distances commence and conclude at the San Pablo Reservoir Visitor Center. Participants can select from 5K, 10K, half marathon, or 35K distances. The event has a participant cap of approximately 300 individuals across all races. Inside Trail Racing organizes this event. The longer distances feature a 6.5-hour time limit, maintaining the structure of a genuine trail race as opposed to a casual reservoir run. The course's distinctive feature is its complete circuit around Briones Reservoir using EBMUD trails, incorporating segments typically accessible only with permits. Expect a mix of moderately technical dirt paths, open fire roads, undulating hills, wooded single-track, winding single and double-track sections, exposed ridgelines, and expansive vistas of the watershed. The 10K, half marathon, and 35K races involve less elevation gain compared to many other Inside Trail events, allowing for faster times while still providing road runners with a true trail challenge. Aid stations are equipped with gels, trail mix, salty snacks, fruit, Coke, and Stroopwafels; however, participants must carry their own water between stations. Finishers receive a tech shirt and a medal, age-group victors are awarded trophies, and one participant receives the unique "Dead Last Finisher" award. Notably, dogs are prohibited despite the race's name.

Half Moon Bay Pumpkin Run sends runners onto the Coastal Trail with a pumpkin waiting for them at the end. It is a race weekend event in Half Moon Bay, California, tied to the Annual Art & Pumpkin Festival, with a Kid's Fun Run, 5K, 10K, and half marathon based around Hatch Elementary School and the Pacific-side trail. Senior Coastsiders hosts it, and the proceeds support programs for local older adults. The route follows coastal paths overlooking the ocean, with rolling but generally fast, flat terrain that works for beginners, fun runners, and people chasing a personal best. The half marathon starts early and has a 3.5-hour cutoff, while the 5K and longer races include chip timing and finisher medals unless runners opt out. The festival side adds the Great Pumpkin Parade, live music, pie-eating contests, costume contests, giant pumpkin displays, and free admission on historic Main Street in the self-styled World Pumpkin Capital.

The PB&J Fuel Run 5K/10K/13.1 SAN FRANCISCO is a running event in San Francisco offering 5K, 10K, and half marathon distances.

While specific route details are not provided, the race emphasizes feel-good miles, a satisfying finish, and the concept of running your own way.

The Golden Gate Half Marathon & 5K is a Sunday race in San Francisco with the bridge at the center of the day. Runners choose between a half marathon and a 5K, with the shorter distance open to both runners and walkers and aimed at a wide range of abilities. The half marathon crosses the Golden Gate Bridge twice, giving runners long looks at the bay, Alcatraz, and San Francisco from one of the city’s most famous landmarks. The event draws runners from around the world, uses the hashtag #RunTheBridge, and is tied to the Bay Area running community as much as to the bridge itself.

Boundary Bay is a late-fall race series held at Boundary Bay Park, Centennial Beach in Delta, British Columbia, offering 5K, 10K, half marathon, marathon, and 4-person marathon relay distances. The marathon is presented as a final opportunity for runners aiming for a Boston qualifying time, featuring a straightforward course: a completely flat gravel oceanside trail with no elevation gain. All distances follow an out-and-back route along British Columbia's southern coast, allowing participants to run beside Boundary Bay instead of through city streets. The course offers views across the Salish Sea towards the San Juan Islands, with migratory birds present and ocean weather as the primary variable. The race supports Ronald McDonald House BC & Yukon. Organizers acknowledge the late-season timing by advising runners to dress warmly, bring dry clothes, and appreciate the clock-change weekend that may provide an extra hour of sleep.

The Veterans Day Freedom Run in San Francisco is a road run at Crissy Field, offering 5K, 10K, and half-marathon distances. It is centered on Veterans Day gratitude, allowing participants to run or walk without the pressure of a competitive race. Waves are capped and may sell out; a waitlist and virtual option are available when in-person spots are full. The event accommodates all paces and ages, with participants under 18 requiring a guardian. Timing is optional; runners may use an app to track and submit results online, or seek assistance from coordinators, as there are no timing chips. Participants can fundraise for a chosen charity, with all net proceeds directed to that cause. Included with registration are a running shirt for U.S. participants, a finisher medal, a towel or giveaway item, a digital training pack, online results, a completion certificate, and an invitation to local running clubs.

The Zoom Turkey Trot begins Thanksgiving morning at Hellyer County Park in San Jose. Runners will use the Coyote Creek Trail, with the Buena Vista Pavilion serving as the race hub. The event offers a 5K, 10K, and a USATF-certified half marathon. A free 50-yard Kids Run is available for children aged 6 and under. Starts are staggered throughout the morning, beginning with the Kids Run, followed by the half marathon, 10K, and 5K. Separate 5K and 10K registration categories exist for younger runners, making the event suitable for families and adults seeking a longer holiday run. The course is largely flat, fully marked, and almost entirely paved. The 5K and 10K routes remain on pavement, while the half marathon includes a short single-track section. Aid stations are positioned every 2 to 4 miles, offering fruit, salty snacks, candy, water, and electrolyte drink. The race is cupless; runners must carry their own bottle or cup. Course rules include passing on the left with a callout, keeping headphones off on single track, road crossings, aid stations, and the finish line, and leaving dogs off the course. Participants receive a custom medal, pre-registered runners get shirts, and age-group awards are given to the top three finishers in each category. The top three male and female runners in each distance receive awards and race credits. A literal Thanksgiving prize is also awarded: runners can win a turkey.

Summit Rock is an early-winter trail race in Sanborn County Park, just outside Saratoga in Northern California’s Santa Cruz Mountains. The series offers a half marathon, 10K, and 5K on forested terrain, with pines, redwoods, oak trees, and miles of single-track trail inside a park of more than 3,600 acres. It is a timed race with electronic chip timing, but walkers and hikers are welcome too, so the field is not limited to runners chasing a fast finish. The half marathon and 10K climb toward peaks, while every distance uses narrow trail under the tree canopy. The terrain is challenging, with enough climbing and descending that new trail runners are encouraged to walk the hills and save energy for flatter or downhill sections. More experienced runners get a tougher mountain-route outing close to Silicon Valley, San Jose, and San Francisco, and all finishers receive custom medals. The race takes its name from Summit Rock, the park peak tied to the event.
