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.

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.

Roosters Backyard Ultra

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

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.

About Marathon races in San Diego

San Diego Training Notes

San Diego hosts 6 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.
