5K races near Fontana

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.

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.

Luz y Vida is a Día de los Muertos run/walk in Riverside, California, with 5k, 10k, 15k, and half marathon options from Ryan Bonaminio Park. A Better World Running organizes it, and the setup is low-key: bib pickup happens the morning of the race, all distances start early, and registration includes a custom finisher medal, a drawstring goodie bag, free photos, free videos, posted results, snacks, and samples. The course uses a marked open path shared with pedestrians, runners, and cyclists, so this is not a closed-road race. The 5k is an out-and-back, the 10k repeats that loop twice, the 15k repeats it three times, and the half marathon uses three 4.36-mile loops. Aid is available at the turnaround and start/finish area with water, Gatorade, and Gu gels. Strollers are allowed, dogs are not, and half marathoners get a 3-hour-15-minute limit with early starts available by request.

Run for Freedom covers races with diverse formats: a West Virginia series near Harpers Ferry and an Oakland 5K coinciding with Black History Month.

The Oakland Freedom Run is a 5K run or walk in West Oakland, beginning and ending at Raimondi Park, prioritizing community involvement over competitive timing. The Harpers Ferry race crosses Harpers Ferry National Park. Runner accounts describe the half marathon encountering cold rain and fog at Antietam, contributing to the event's strong Civil War history atmosphere. The Oakland route winds past historic Black Panther Party sites, linking the run to themes of freedom, justice, and health equity. Registration operates on a sliding-scale contribution, with proceeds benefiting the Black Panther Party Alumni Legacy Network's survival programs. The race is accompanied by a free wellness festival providing health screenings, food, massage, therapy, and information from local groups focused on nutrition, exercise, stress management, and preventive care.

The Redlands Educational Partnership Foundation and Redlands Sunrise Rotary Club are the organizers, with all proceeds benefiting Redlands schools and local charities.

The Five Star Thanksgiving Turkey Trot is an Atlanta race held on Thanksgiving morning, offering live 5K, 10K, 15K, and half marathon races, along with virtual options for each distance. The event is intentionally low-cost; runners not qualifying for free entry can register for a small fee, with race-day registration costing slightly more. The race originated from the organizers' decision, two weeks before Thanksgiving, to acknowledge participants from that season's races. This tradition continues: finishers from other Five Star races qualify for one free live 5K entry, though the Turkey Trot itself does not count towards this free spot. Shirts, hoodies, and finisher medals are available as optional purchases, allowing runners to customize their participation.

The Reindeer Run Riverside is a holiday-season run/walk held at Ryan Bonaminio Park in Riverside, California, offering 5k, 10k, 15k, and half marathon distances. The start and finish are located at the park's far end. Bib pickup occurs at the park on weekend mornings, with free parking available in the park lot and along Tequesquite Avenue.

The 5k is a single out-and-back, the 10k is two repetitions of the 5k loop, the 15k is three repetitions, and the half marathon uses three 4.36-mile loops with a 3:15 time limit. Restrooms are situated near the start and finish. The aid station at the turnaround point provides water, Gatorade, and Gu gels. Strollers are permitted, but dogs are not.

The race attracts significant local attention, with every distance having sold out in a past event. Participants receive long-sleeve tech shirts, finisher medals, and age-group awards.
