Spooky Dash 5k, 10k, 15k, Half Marathon
Spooky Dash is a Halloween-themed race series in Long Beach offering four distances: 5k, 10k, 15k, and half marathon. It accommodates a broad range of participants, from families and novices to those seeking a longer beach run. The course is straightforward: runners use a public path, sharing it with pedestrians and cyclists, and follow marked out-and-back loops.
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. Aid stations are located at turnarounds and the start/finish, providing water, Gatorade, and Gu. Registration includes a custom finisher medal, a drawstring bag, complimentary race photos, snacks, samples, and online results available soon after the event.

SoCal's Sunset Trick or Trot 5k/10K - Halloween Race
Monster Dash 5k, 10k, 15k, Half Marathon
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.
Trick or Trot 5K, 10K, and Half Marathon by Califlow Runs
Costumes are integral to Trick or Trot, a Halloween-themed run held by the sea in Long Beach, California. CaliFlow Runs hosts the event at 5400 E Ocean Blvd, offering a 5K, 10K, a USATF-certified half marathon, and a Kids 200 Yard Dash. The half marathon begins in the morning, followed by the 5K and 10K. All distances employ a group wave start.
The race route follows a paved coastal out-and-back path, shared with walkers, strollers, and beachgoers. This creates a public beach morning atmosphere with added race timing, rather than a closed-road city event. The 5K consists of one loop, the 10K of two loops, and the half marathon of three loops, totaling a certified 13.1 miles. Half marathoners may request an early start via email; however, early starters are ineligible for awards. Water stations and restrooms are available along the course. The top three male and female finishers in each distance receive medals, and runners also receive evening results and complimentary race-day photos.
The Long Beach Halloween Run 5K. 10K. Half Marathon by Califlow Runs
The Long Beach Leprechaun Run begins at Granada Beach, adjacent to Rosie’s Dog Beach, located at 5100 E Ocean Blvd in Long Beach, California. This St. Patrick’s Day-themed running event offers a Kids Dash, 1 Miler, 5K, 10K, and Half Marathon, allowing families and longer-distance runners to participate on the same race morning. The event uses chip timing, the course is clearly marked, and there are no late starts. The half marathon starts first in the early morning, followed by the 5K and 10K, and then the 1 Miler and Kids Dash. Restrooms are situated near the start, aid stations are placed approximately every two miles, and the event accommodates walkers and strollers.
The 5K, 10K, and Half Marathon follow the Long Beach waterfront. Irish-themed cheer zones are present along the route, and golden coins are hidden on the course for runners to discover and exchange for prizes. A costume contest encourages participants to wear green attire, and all finishers receive a custom medal along with festive refreshments. Children have their own Little Leprechaun Dash, and the Shamrock Treasure Hunt is available for kids not participating in the races. The finish area maintains the theme with photo opportunities featuring pots of gold and rainbows, contributing to the event's character as a community-focused race.
Happy Halloween 5k, 10k, 15k, Half Marathon
The Happy Halloween 5k, 10k, 15k, and Half Marathon is a Halloween morning race in Long Beach, starting at 7:30 AM. It offers four distance options on the same beach-path setup. This event is designed for runners seeking a straightforward, low-pressure race instead of a complex point-to-point course. The distances vary from a single 5k to a half marathon composed of repeated loops.
The course features marked out-and-back loops on an open beach path, shared with pedestrians, cyclists, and other users. The 5k is one out-and-back, the 10k is two repetitions, the 15k is three, and the half marathon consists of three 4.36-mile loops. An aid station at the turnaround provides water cups, water bottles, Gatorade, and Gu gels. Registration includes a custom finisher medal, a drawstring goodie bag, free photos, results posted within 12 to 24 hours, snacks, and samples. Group discounts are available for parties of five or more.
DINO DASH
Dino Dash is a Tustin school fundraiser offering running, walking, and cycling options on the same day. Proceeds benefit the Tustin Public Schools Foundation. The event caters to families and racers alike, featuring a 2k fun run, chip-timed 5k and 10k runs, and bike tours for various skill levels, including 15k and 5k family rides.
Almost 10,000 participants, including runners, walkers, cyclists, volunteers, and sponsors, attended the last event, demonstrating strong community involvement. The race has a history spanning over thirty years. Its student-created identity contributes to its appeal: a student from Legacy Magnet Academy won the logo competition with a dinosaur carrying companions, a design featured on bibs, shirts, posters, flyers, and social media. The event also provides direct support, with donations covering entry fees for students requiring financial assistance.
Día de Muertos - Viva la Vida - 5K, 10K, and Half Marathon by Califlow Runs
Viva la Vida is a Day of the Dead-themed beach race in Long Beach, California, beginning and ending at 5400 E Ocean Blvd. Participants can select a 5K, 10K, half marathon, or 1-mile run. The half marathon starts early, with shorter races commencing afterward. The event is chip-timed, offers awards, and provides finishers with a medal, appealing to both competitive runners and those enjoying the theme.
The course utilizes the Ocean Boulevard beach area, featuring water stations and restrooms. A firm late-morning cutoff is in place. Califlow Runs embraces the Día de Muertos theme, encouraging participants to wear marigolds, skull face paint, skeleton attire, or other costumes. A costume contest with prizes is included.

Inland Empire Miles And Rides
Riverside-San Bernardino-Ontario, CA hosts 95 10K races in 2026 within 80 km of the city centre — upcoming dates, recurring series, and other races nearby, all in one place.
Riverside runners get a useful mix of park loops, city miles, and longer Inland Empire routes. Ryan Bonaminio Park gives Golden Strides 5k, 10k, 15k, Half Marathon runners a familiar anchor. ASP Run Club brings the weekend long social run on Saturdays at 7:00 AM PDT. ASP Chino Hills Social Run meets every Monday at 6:00 PM PDT. UC Riverside puts the PA for LA 5K at the Bell Tower. Mission Inn Run, Citrus Heritage Run, Pink on Parade, Reindeer Run Riverside, and Steps For Vets 5K keep the race calendar busy. The longest route covers 40 km and gains 458 m.
Riverside Bicycle Club is the big local name on the bike. The club started in 1891, has over 200 members, and puts on over 400 rides a year. The club rides Tuesday, Thursday, Saturday, and Sunday, with A, B, C, and D groups. The Saturday Casual Ride stays short and mostly flat, with a regroup in the middle to socialize. The route covers 8 km with 246 m of ascent and 474 m of descent. The route reaches 543 m, so the climbing is real. Baldy via Devil's Backbone is the hard altitude day.

Summer keeps runners on 5K to half marathon options like Luz y Vida, Golden Strides, and Highland Family YMCA, with base miles and intervals fitting around club meets. Summer also keeps cyclists on regular Riverside Bicycle Club days and the Riverside Citrus Classic 2026 target. Winter changes the rhythm more than the map. Runners keep steady Z2 on routes like My Favorite Redlands 10 and The Loop. Cyclists stay practical, using cycleway, quiet road, road, paved, asphalt, and short unpaved sections when the plan calls for it.
