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.

The Run for Education is a spring 5K, 10K, and Kids Fun Run held in El Segundo, California. Its purpose, reflected in the name, is to raise funds for the city’s K-12 public schools. The El Segundo PTA Council organizes the event, which is now in its fourth decade. The 5K and 10K courses are USATF-certified, winding through downtown El Segundo and adjacent neighborhoods. These routes offer a measured course for competitive runners and a straightforward local path for casual participants. The field comprises competitive racers, joggers, walkers, families, and children. Age-group medals are awarded to the top three finishers in the 5K and 10K, with medals given to all participants who finish a race.

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.

Diablo Trails Challenge starts and finishes at Castle Rock Recreation Area in Diablo Foothills Regional Park in Walnut Creek, with Mount Diablo as the main playground. Brazen Racing hosts the trail-running series, which offers a 5K, 10K, half marathon, and 50K, so the same event can suit a first trail race or a long day out for experienced ultra-runners. All races are professionally timed, finishers receive medals, and the event is part of the Ultra Half Series. The longer routes reach well beyond Castle Rock, linking parkland such as Round Valley, Los Vaqueros Watershed, Morgan Territory, Mount Diablo State Park, and Shell Ridge Open Space before returning to the start area. The half marathon is listed as a 13.5-miler and includes hill climbing, quick descents, and runnable rolling sections. The race also serves a local conservation purpose: it raises money for Save Mount Diablo, with part of every entry fee going to the group. Save Mount Diablo has spent more than 50 years preserving and expanding open space around the mountain, helping grow protected land from 6,788 acres to more than 120,000 acres.
