Recurring Half Marathon races near San Diego
Races that repeat — weekly, monthly or yearly
Pacific Beach Half Marathon & 5K
The Hoag OC Marathon Running Festival is a road-race weekend in Orange County, California, featuring a sunset 5K on Saturday and the half marathon and full marathon on Sunday. The longer races begin at Fashion Island, the outdoor shopping mall in Newport Beach, with the 5K starting and ending at the OC Fair & Event Center. The event, held annually, originated from an Orange County marathon that offered equal prize money for its first male and female winners.
The half and full marathon course departs from Newport Beach onto Pacific Coast Highway, proceeds through Corona del Mar, passes Newport Bay, and then heads inland along residential streets near Upper Newport Bay. The half marathon diverts towards the OC Fair & Event Center around the 12-mile point, while the marathon continues through Costa Mesa, passing the Orange County Museum of Art, Segerstrom Center for the Arts, and South Coast Plaza, before entering Santa Ana and returning south on the Santa Ana River Trail to the fairgrounds. The 5K route remains closer to Costa Mesa, passing Orange Coast College.
ERS SEASON PASS
The ERS Season Pass is a trail-running registration package for Endurance Race Series events in the Colorado and San Diego areas. It functions as a season-long VIP pass: runners register for every ERS race in their selected market through a single transaction and package price, rather than entering each event individually.
The Half Marathon Package is priced at $400 and includes six Southern California races: Carmel Valley 10 Mile, Black Mtn Half, Dixon Lake 10 Mile, Del Dios Half, SPV Half, and Coast to Crest 10K. Pass holders receive a VIP goodie bag, and participants completing five of the six races earn a Season Pass medal and an ERS-branded gift. The package also includes entry into the Legacy Program and the Championship Series, making it suitable for individuals intending to compete in the entire series rather than just one race.
The Peak 50K, Marathon & Half Marathon
The Peak is a mountain trail race at Cuyamaca Peak in San Diego County, offering 50K, marathon, and half marathon distances. The longer races begin early, with the half marathon starting an hour later. This is not a gentle run: the 50K and marathon ascend over 2,200 feet in the initial 6.3 miles, reaching Cuyamaca Peak, San Diego County’s second-highest summit, before the marathon descends 2,800 feet to Sweetwater Aid Station. The marathon course has an 8.5-hour time limit, the 50K allows 10 hours, and the half marathon cutoff is 4.5 hours.
All three distances commence at Camp Hual-Cu-Cuish and utilize single-track trails. The half marathon follows the same initial route as the longer races up Conejos Trail before returning to the start/finish area. Marathon runners turn around at Sweetwater Aid Station, then climb back to Cuyamaca Peak on their return, accumulating up to 10,000 feet of total elevation change. The 50K includes a five-mile loop from Sweetwater before rejoining the marathon's return path, meaning those runners pass Sweetwater twice. The event is part of the SoCal Ultra Series, its trails are maintained by Trailfit volunteers under Ken Bonus, and a local detail includes a discount on handmade ice-pocket bandanas from T’s Cool Downs, with a portion of sales benefiting Malan Syndrome Research.
2026 BINATIONAL RACE
The Binational Race is an October running event connecting San Diego and Tijuana. The most direct route begins in San Diego, crosses the U.S.-Mexico border mid-race, and concludes at the beach in Playas de Tijuana. Participants can select a half marathon, a 12K, a Tijuana-only 10K, or a virtual option. Now in its third edition, the event's structure is designed to bring people from both sides of the border together on a single course and at one finish line.
The half marathon and 12K utilize the San Ysidro-El Chaparral crossing, traverse the Tijuana River Valley Regional Park, proceed along Avenida Internacional, and finish with a quick downhill run toward Playas de Tijuana. The 10K starts and ends in Tijuana, allowing participants who prefer not to cross the border to join the same beachside finish and post-race activities. The field comprises runners from diverse cultures and backgrounds, and the race was established with backing from both communities following discussions with city officials on both sides. All finishers receive a medal, complimentary race photos, and a timed result; half marathon and 12K runners also get the official shirt.
Crown Point Relay Runs
Crown Point Relay Runs takes place on a morning at Crown Point Park in San Diego, offering 5K, 8K, half marathon relay, and marathon relay options. The relay races begin early, followed by the 8K and then the 5K. This schedule means the longer team events are underway within the park before the shorter races commence. Relay teams consist of 2 to 5 runners; the half marathon relay spans 5 laps and the marathon relay covers 10 laps.
The course follows a paved bike path alongside the calm waters of Mission Bay. It features a flat, fast profile with broad bay views. The course suits walkers, newer runners, club runners, and teams aiming for a fast finish. However, the relay format lends a more social atmosphere than a typical road race. Teams receive a picnic area, chipped timing, shirts, medals, and overall and age-group awards. Active and veteran military or service members are eligible for a registration discount.

Thrive San Diego Half Marathon & 5K
The Thrive San Diego Half Marathon & 5K takes place in November at Ski Beach in Mission Bay, San Diego. All courses begin and end at this location. The primary event is a 13.1-mile half marathon, with additional options including a 5K, a two-person half marathon relay, charity entries, and virtual half marathon and 5K races. This marks the series' tenth year. The morning begins with the half marathon and relay, followed by the 5K.
The half marathon course is a loop starting on Ingraham Street, proceeding along Mission Bay, and returning to Ski Beach. It features flat, fast sections, bay views, and ocean breezes, avoiding significant hills or complex terrain. Relay participants cover approximately 6.5 miles each over the 13.1-mile distance. The race benefits Make-A-Wish San Diego and promotes community well-being through activity, healthy eating, and charitable contributions.
San Diego 50 & Trail Runs
San Diego 50 & Trail Runs offers a trail race series in San Diego centered on a 50-mile ultra. Shorter distances accommodate marathoners, relay teams, new trail runners, parents with strollers, and children. The 50M is presented as a suitable first 50-mile race or an accessible ultra. The event also features a trail marathon, a half marathon, the Summit Chase 10M, the Valley 5M, the Stroller Trail 5K, and a 1 Mile Fun Run for children 10 and under.
Raptor Ridge is a key course feature. The trail marathon crests at Raptor Ridge, and the Summit Chase 10M goes to the summit and back, with the winner taking the title. The marathon relay divides the marathon into two 13.1-mile segments, with handoffs at Piedras Parking Trail Head Parking Lot rather than using a shuttle. The Valley 5M and Stroller Trail 5K are flat courses, and the kids' mile is untimed but includes finisher medals. The series is cupless; participants must provide their own bottle, cup, or hydration pack for aid stations.
2027 CARLSBAD MARATHON, HALF MARATHON & 5K
The Carlsbad Marathon, Half Marathon & 5K takes place in Carlsbad, California, during the Martin Luther King Jr. holiday weekend. Participants can select the full 26.2-mile marathon, 13.1-mile half marathon, or 3.1-mile 5K. A Double Down Challenge is available for those completing the 5K and half marathon, totaling 16.2 miles. All race distances can also be completed virtually.
The courses offer ocean views for participants, with 26 staffed aid stations and ongoing entertainment. The event is presented as a boutique race, focusing on course support, volunteer assistance, and personalized service. Finishers will receive a long-sleeve technical shirt, a quarter-zip pullover, a reusable grocery bag, and a finisher medal. Registration is limited and known to sell out.
Del Dios Trail Race
The Del Dios Trail Race begins at the Lake Hodges Boat Ramp Lot in Escondido, California. All race distances are run entirely on dirt. The event is known as the “Race of the Gods,” offering runners multiple options on the same rugged terrain: 50K, half marathon, 10K, 5K, and a 15K relay for three-person co-ed teams. This annual trail race, with over ten editions completed, focuses on lake-country trails instead of paved surfaces.
The course features dirt service roads and maintained single-track. The amount of climbing varies by distance, and the terrain is technical enough to avoid feeling like a casual lakeside run. Participants start from the boat ramp area, heading out along Mission Road and the Coast to Crest Trail before returning the same way. The relay format is straightforward: each teammate completes the 5K course, and teams must consist of both men and women. The boat ramp area is closed to the public during the event, requiring runners, staff, and volunteers to use parking passes provided with race-day information.
San Pasqual Valley Trail Race
The San Pasqual Valley Trail Race begins on Bandy Canyon Road in Escondido, located in San Diego County's wine region. Participants can select from 20-mile, half marathon, and 10K distances; some event listings also mention a 1K option. This trail race is set on vineyard roads, through orange groves, across grass fields, and along dirt trails, distinct from urban courses. Now in its tenth year, the race is designed for trail runners seeking a demanding course.
The course starts on private land before proceeding along Bandy Canyon Road and dirt paths through San Pasqual Valley. Raptor Ridge presents the primary challenge: the half marathon route involves an out-and-back journey up and down the ridge twice. The ascent features switchbacks and offers expansive valley views. The landscape combines active wine country with citrus orchards, and local wine is available to runners at the finish line, continuing the regional theme.

About Half Marathon races in San Diego
San Diego Training Notes
San Diego hosts 27 Half Marathon races in 2026 within 80 km of the city centre — upcoming dates, recurring series, and other races nearby, all in one place.
San Diego runners get a real mix: waterfront flats, canyon dirt, beach boardwalk, and hill work when you want it. Locals stack base miles on the Embarcadero, Liberty Station, Shelter Island, Coronado, and the Mission Beach to Pacific Beach boardwalk. Mission Bay gives you 12 paved miles with bathrooms and water fountains, so long runs stay simple. Balboa Park and Mission Trails Regional Park handle trails, intervals, and Z2 days without feeling far away. November Project meets Mondays and Wednesdays at 6:29 AM in Balboa Park, and La Jolla Track Club meets Tuesdays at 5:30 PM at UCSD Triton Track. Pacific Beach Half Marathon & 5K, San Diego Santa Run, Lake Hodges Trail Festival, and RnR half marathon keep the calendar honest.
San Diego riders live between coast miles and inland punch. SDBC has been around since 1946, and its World Famous Saturday ride has seven different pace groups. The coastal route runs 4 miles when you want clean coastal spinning. North County gravel gets serious on Coastal Gravel Route, Best of North County Gravel Route, RSF Gravel Route, and Lusardi Gravel Route. 8% for just under two miles. Mount Palomar gives climbers the 6,140-foot target. Barrio Logan Grand Prix, Bike the Bay, San Diego Century, and Giro di San Diego GranFondo are the anchor events.
Spring works well for running and riding, with March through May staying mild and steady. Fall gives September through November the same conditions, so locals keep base miles and bigger weekend rides going. Summer runs warm and dry, and August highs sit around 25C near the coast. The marine layer brings May gray and June gloom, so coastal Z2 can feel cooler while inland miles heat up fast. Winter stays mild, with January lows around 8C, but December through March brings most of the rain. Trails at Mission Trails Regional Park, Lake Hodges singletrack, and North County gravel need a little more timing after wet days.
