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 event typically draws between 1,000 and 5,000 participants, creating a busy, community-focused atmosphere. The courses are noted for being fast and flat, suitable for beginners, families, and those aiming for a consistent pace. The half marathon is not a Boston Qualifier. The event incorporates the holiday spirit through its shirts, post-race activities, and finisher medals for human and canine participants. Packet pickup is offered the day before and on race morning, with parking at Davis High School and bib pickup located near the finish line on race day.

The Thanksgiving Turkey Gobble Trot is a Sacramento run and walk held at Sutter's Landing Regional Park during the Thanksgiving season. Runners and walkers can choose a 5K, 10K, or half marathon, and there is also a virtual option for people who want to cover the distance on their own. The event is built for families and casual participants as much as regular runners, with all ages and paces welcome and under-18s needing a guardian. The setup is simple: pick a distance, bring friends or family, and run or walk before the holiday meal. The organizer leans into the Thanksgiving theme with the line “run so we can feast,” and the event is promoted as a community outing rather than a race that demands special gear or experience. Coordinators are on hand to support participants, which fits the relaxed format and makes the longer distances less intimidating for people setting a holiday fitness goal.
