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 Crystal Springs Trail Run begins at Huddart Park in Woodside, California, leading runners into the wooded paths surrounding King’s Mountain and Bear Gulch. This winter trail race offers distances from a 5-mile run to an ultramarathon, including a half marathon, 22 miles, a marathon, and a 50K. A free 50-yard dash is also available for children aged 6 and under. Established in 2006, the event does not offer prize money, fostering a community atmosphere rather than a professional competition. The course is predominantly unpaved, with approximately 95% of the route on dirt trails, featuring a total elevation gain of 4,810 feet. Participants will traverse redwood forests and areas dense with ferns. The organizers emphasize trail etiquette, requesting runners announce passes, remain on marked paths to avoid poison oak, and refrain from using headphones on single-track sections, road crossings, aid stations, and near the finish line. Bibs indicate each runner's chosen distance, and participants can change their race distance via email or during check-in.

The Golden Gate Trail Run is a winter trail race in San Francisco offering distances for various runners, from an 8K and half marathon to marathon, 50K, and longer ultra options in the Spartan Trail version. A free 50-yard dash for children aged six and under is also available, showing the event caters to more than just ultrarunners. The running surface is soft trail, the route is hilly, and typical conditions are mild, around 64°F. The course takes runners across the Golden Gate Bridge and into the Marin Headlands, with views over the Pacific Coast, Tiburon, San Francisco, and the bridge. The average altitude is low at about 426 feet, but the Headlands provide significant climbing and exposed coastal trail running, distinct from a flat city route. Volunteers can earn credits toward other U.S. Spartan events, and published results are available for several recent editions.

The Montara Mountain Trail Run is a February trail-running series held in San Pedro Valley Park, Pacifica, California. The main races begin in the morning, offering runners a selection of distances: 10K, half marathon, 20.7 miles, marathon, and 50K. A free 50-yard dash is available for children aged six and under, alongside a free Coastal Testing event that starts before the main races. The course ascends Montara Mountain, an area noted by the race organizers as the sole undisturbed coastal mountain habitat along over 100 miles of coastline. Participants will run past huckleberry, honeysuckle, lilac, chinquapin, and manzanita groves, with views of the Pacific Coast appearing as they climb. The event likely attracts a diverse field because of the range of distances from a short trail race to an ultramarathon, and the kids' dash encourages families to attend before the longer races commence.

The Oakland Marathon takes place over a weekend in March in Oakland, California. It offers a full marathon, half marathon, 10K, 5K, and a Kids Fun Run. Kaiser Permanente presents the full marathon. The event is designed for a broad spectrum of runners, not exclusively marathon specialists. The expo, kids run, and race festival also attract spectators and families who are not participating. The marathon course is a single loop passing through Oakland landmarks and crosses the Bay Bridge. The finish line is at the Henry J. Kaiser Center for the Arts, a location also noted as a good vantage point for the final stretch. The full marathon is known among runners for its scenic and challenging terrain. The event collaborates with Stephen and Ayesha Curry’s Eat. Learn. Play. Foundation, with race entries, donations, and fundraising benefiting local youth.

The Redwood (Spring) Trail Run is a spring trail-running event held at Chabot Space & Science Center in Oakland, with races taking place within Redwood Regional Park. Participants can select from a short sprint or 5-mile run up to a half marathon, 30K, marathon, and 50K, accommodating children, novice trail runners, and those seeking a long run on trails.

The children's 50-yard dash is complimentary for ages six and under, youth 5-mile divisions offer reduced entry fees, and the primary adult distances commence in the morning. Distances are measured using a Rolatape surveyor’s wheel, a detail important for trail courses where GPS accuracy can be affected by tree cover and terrain.

The SPASM Lake Chabot Trail Run begins at the marina in Lake Chabot Regional Park, Castro Valley, California. Runners follow dirt paths around the reservoir and adjacent hills.

The event, established in 2010, caters to those preferring a trail run over a road race. The course encircles Lake Chabot Reservoir, constructed to supply water for the East Bay.

Organizers use a Rolatape surveyor's wheel for distance measurements. The event accommodates novice trail runners, experienced long-distance participants, and families, offering a free 50-yard kids' dash for children aged six and under.
