The course is chip timed, fast, and gently rolling, allowing runners a competitive 5K while walkers and rollers navigate a manageable park route. The setup is straightforward: snacks are provided before and after the race, the theme encourages costumes, and the format places first-timers, families, and regular runners on the same course.

Spooky Dash is a Halloween-themed race series in Long Beach offering four distances: 5k, 10k, 15k, and half marathon.

The 5k is a single out-and-back, the 10k is two laps, and the 15k is three laps. The half marathon consists of three 4.36-mile loops, making the structure clear before race day.

Bubble Run Irvine is a family-friendly foam run at Oak Canyon Park in Silverado, California, near Irvine. It follows a relaxed 5K-style format, focusing on participation rather than speed: adults, kids, and people with strollers can run, walk, dance, or play their way across up to 3 miles. Participants typically begin in white T-shirts, allowing the colored foam to create a visual effect by the finish. The course guides participants through Foam Bogs, each containing a different color of 100% safe foam and ample bubbles to coat everyone from head to toe. Staff, known as Bubble-teers, assist in ensuring participants are thoroughly foamed. The event's description likens the experience to moving through Willy Wonka’s factory. Starts are organized in waves, with heats divided into smaller groups, contributing to a day that feels more like a continuous family festival than a standard road race.

The RunThrough USA Long Beach Race Weekend offers a 5K, 10K, and half marathon, starting at Shoreline Aquatic Park in Long Beach, California. Participants can select from 3.1 miles, 6.2 miles, or 13.1 miles along the coast of the Los Angeles area.

Post-race, the event village will offer food and beverages, including hot coffee and complimentary partner items.

Before sunrise, runners begin on Shoreline Drive for the 2XU Long Beach Marathon, a 26-mile, 385-yard road race in Long Beach, California. The race weekend also features a half marathon, which can attract a larger field than the full marathon. The event originated in the early 1980s, paused during the 1990s due to financial difficulties, and then resumed under new leadership. Recent marathons have seen thousands of participants, a full half marathon field, and runners representing dozens of countries. The course covers much of Long Beach in a single loop. It directs runners through The Pike at Rainbow Harbor, onto a 710 Freeway on-ramp, over Queensway Bridge toward the Queen Mary, around the Rainbow Harbor lighthouse, and returns through the start area before heading toward the ocean. The middle section runs alongside the Pacific, through Belmont Shore, past Marine Stadium, around Colorado Lagoon, and by Long Beach Recreation Golf Course. Miles 16 to 20 involve a loop through Cal State Long Beach, after which Ocean Boulevard leads runners back to the Shoreline Drive finish. Local runner Kenny Williams completed every edition for the race's first forty years, and multiple other individuals had not missed a race weekend.

The Long Beach Race for Rare is a 5K run and walk held at Granada Launch Ramp on East Ocean Boulevard in Long Beach, California. The morning features a timed 5K run, a 5K walk, a virtual 5K option, and a picnic-only entry for those wishing to support the cause without participating in the course. Local hosts Lynn and Scott Hopkins coordinate the event with the National MPS Society, with proceeds benefiting that group’s efforts for families affected by MPS and ML conditions. The event begins with onsite registration, packet pickup, and pre-race entertainment prior to the 5K. It then proceeds to awards, a raffle, and a beachside picnic with lunch included in registration. The cause is the primary motivation for attendance: rare diseases impact approximately 10% of Americans, fewer than 5% have an FDA-approved treatment, and many children with rare conditions pass away at a young age. This is a community race, not an elite competition, centered on families, local supporters, walkers, runners, and individuals raising awareness for rare disease care and research.

The Montebello Heritage 5K/10K is an annual October running event in Montebello, California, offering both 5K and 10K distances. Both races begin at 1301 W.

The course follows historic Whittier Boulevard, connecting the race to a central Montebello street. This is a community-focused race, not exclusively for elite runners. The entry fee is the same for both distances, and all participants receive a shirt and medal.

The Boyle Heights 5K Run/Walk is a community race in Los Angeles, starting and finishing at Mariachi Plaza. Participants cover 3.1 miles in the 5K event, which takes place in October with a morning start and late-morning finish. The day includes more than just the main 5K. A Munchkin Run is available for younger children, and a Classic Car Show is part of the gathering, contributing to a neighborhood feel rather than a standard road race. The Mariachi Plaza start and finish locate the race in one of Boyle Heights’ most recognizable public spaces.

Pink on Parade is a breast cancer awareness walk held at Ryan Bonaminio Park in Riverside, California. It is designed for families, teams, survivors, supporters, and those bringing pets, offering a 5K route or a shorter 1.7K Family Fun walk around the park. The 5K route can incorporate Mt. Rubidoux and is structured around the cancer journey. The shorter option makes the day accessible for children and casual walkers. The event honors survivors, remembers those lost to cancer, and directs all proceeds to The Pink Ribbon Place, a local resource center assisting individuals and families impacted by cancer. Beyond the walking paths, the event features a survivor pavilion, vendor expo, kids zone, food and beverages, a pre-walk stretch, team awards for fundraising and spirit, a T-shirt design competition, merchandise, and a classic car show displaying imports and domestics from the 1940s to the 1980s.

The Monster Dash is a Halloween-season beach-path race series offering four distances that begin simultaneously at 7:30 AM: 5k, 10k, 15k, and half marathon. It is designed for runners seeking a straightforward, uncomplicated morning race, featuring bib pickup prior to the start, custom finisher medals, drawstring goodie bags, complimentary participant photos, snacks and samples, and results published online within 12 to 24 hours. The course consists of marked out-and-back loops on an open beach path, meaning runners will share the route with other pedestrians, runners, and cyclists. The 5k comprises a single out-and-back, the 10k involves completing that loop twice, the 15k requires three repetitions of the loop, and the half marathon utilizes three longer loops, each measuring 4.36 miles. The turnaround aid station is equipped with water cups, water bottles, Gatorade, and Gu gels. Groups of five or more runners are eligible for a discount, and volunteering provides a free race entry, even if a friend or family member volunteers while the runner participates.
