ナパ, CA周辺のHalf Marathonレース

The Windsor Marathon begins and ends at The Island at Pelican Lakes in Water Valley, Windsor, Colorado.

The course incorporates golf-course paths, the Poudre River trail, inclines, and single-track dirt trail sections for the marathon.

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.

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 Golden Gate Half Marathon & 5K is a Sunday race in San Francisco with the bridge at the center of the day.

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.

The Veterans Day Freedom Run in San Francisco is a road run at Crissy Field, offering 5K, 10K, and half-marathon distances.

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 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.
