Recurring Half Marathon races near Santa Rosa-Petaluma
Races that repeat — weekly, monthly or yearly
Windsor Marathon, Half Marathon, 10k, 5k & 1 Mile Run
The Windsor Marathon begins and ends at The Island at Pelican Lakes in Water Valley, Windsor, Colorado. The event offers a full marathon, half marathon, 10K, 5K, and a 1 Mile Fit & Fun Run, accommodating marathoners, shorter-distance runners, and children.
The course incorporates golf-course paths, the Poudre River trail, inclines, and single-track dirt trail sections for the marathon. The marathon commences earlier than the other races, with the 1-mile run scheduled for later in the morning. Post-race, participants can enjoy breakfast, beverages, and music at the finish area. The event supports Banner MD Anderson Cancer Center and the Weld RE-4 Foundation.
Reservoir Dogs Trail Run
The Reservoir Dogs Trail Run is an October trail race held at San Pablo Reservoir, located near Orinda in the East Bay. All race distances commence and conclude at the San Pablo Reservoir Visitor Center. Participants can select from 5K, 10K, half marathon, or 35K distances. The event has a participant cap of approximately 300 individuals across all races. Inside Trail Racing organizes this event. The longer distances feature a 6.5-hour time limit, maintaining the structure of a genuine trail race as opposed to a casual reservoir run.
The course's distinctive feature is its complete circuit around Briones Reservoir using EBMUD trails, incorporating segments typically accessible only with permits. Expect a mix of moderately technical dirt paths, open fire roads, undulating hills, wooded single-track, winding single and double-track sections, exposed ridgelines, and expansive vistas of the watershed. The 10K, half marathon, and 35K races involve less elevation gain compared to many other Inside Trail events, allowing for faster times while still providing road runners with a true trail challenge. Aid stations are equipped with gels, trail mix, salty snacks, fruit, Coke, and Stroopwafels; however, participants must carry their own water between stations. Finishers receive a tech shirt and a medal, age-group victors are awarded trophies, and one participant receives the unique "Dead Last Finisher" award. Notably, dogs are prohibited despite the race's name.
Clo Cow Half Marathon, 10K & 5K
Halloween Trick or Trot Run 5K/10K/13.1 SAN FRANCISCO
The Halloween Trick or Trot Run is a Halloween road race held at Crissy Field in San Francisco. Participants can select a 1 Mile, 5K, 10K, or half marathon, accommodating those seeking a brief, enjoyable run and those targeting 13.1 miles.
The race takes place in San Francisco County, within the Bay Area. The start is located at Crissy Field, and the course map is emailed to participants. The Halloween theme is integral to the event; participants are encouraged to bring a friend, set a goal, and receive free Halloween candy post-run.
PB&J Fuel Run 5K/10K/13.1 SAN FRANCISCO
The PB&J Fuel Run 5K/10K/13.1 SAN FRANCISCO is a running event in San Francisco offering 5K, 10K, and half marathon distances. Organized by The Best Races, its peanut butter and jelly theme lends a playful tone rather than intense race-day focus.
The event features a relaxed atmosphere. Participants are encouraged to "spread the fun" and approach the day with "no stress, no expectations," running at their own pace. While specific route details are not provided, the race emphasizes feel-good miles, a satisfying finish, and the concept of running your own way.
Golden Gate Half Marathon & 5K
The Golden Gate Half Marathon & 5K is a Sunday race in San Francisco with the bridge at the center of the day. Runners choose between a half marathon and a 5K, with the shorter distance open to both runners and walkers and aimed at a wide range of abilities.
The half marathon crosses the Golden Gate Bridge twice, giving runners long looks at the bay, Alcatraz, and San Francisco from one of the city’s most famous landmarks. The event draws runners from around the world, uses the hashtag #RunTheBridge, and is tied to the Bay Area running community as much as to the bridge itself.
Veterans Day Freedom Run 5K/10K/13.1 SAN FRANCISCO
The Veterans Day Freedom Run in San Francisco is a road run at Crissy Field, offering 5K, 10K, and half-marathon distances. It is centered on Veterans Day gratitude, allowing participants to run or walk without the pressure of a competitive race. Waves are capped and may sell out; a waitlist and virtual option are available when in-person spots are full.
The event accommodates all paces and ages, with participants under 18 requiring a guardian. Timing is optional; runners may use an app to track and submit results online, or seek assistance from coordinators, as there are no timing chips. Participants can fundraise for a chosen charity, with all net proceeds directed to that cause. Included with registration are a running shirt for U.S. participants, a finisher medal, a towel or giveaway item, a digital training pack, online results, a completion certificate, and an invitation to local running clubs.
A Merry Christmas Run 5K/10K/13.1 SAN FRANCISCO
Jingle All the Way: A Merry Christmas Run is a holiday race series in San Francisco offering 5K, 10K, and half-marathon distances. A Family 1 Mile Fun Run is also available for those not wanting to commit to longer distances, and a virtual run option exists for remote participation.
The event is scheduled before Christmas celebrations, encouraging families and friends to gather. The theme focuses on Christmas values like spreading love, selfless giving, and enjoying time with others. The 5K, 10K, and half-marathon registrations include an eco-registration option for participants who prefer not to receive a shirt.
Golden Gate Trail Run
The Golden Gate Trail Run is a winter trail race in San Francisco offering distances for various runners, from an 8K and half marathon to marathon, 50K, and longer ultra options in the Spartan Trail version. A free 50-yard dash for children aged six and under is also available, showing the event caters to more than just ultrarunners. The running surface is soft trail, the route is hilly, and typical conditions are mild, around 64°F.
The course takes runners across the Golden Gate Bridge and into the Marin Headlands, with views over the Pacific Coast, Tiburon, San Francisco, and the bridge. The average altitude is low at about 426 feet, but the Headlands provide significant climbing and exposed coastal trail running, distinct from a flat city route. Volunteers can earn credits toward other U.S. Spartan events, and published results are available for several recent editions.
Beer City Half™ Santa Rosa
The Beer City Half Santa Rosa begins at A Place to Play in Santa Rosa, California, offering a half marathon, 10K, 5K, and 1-mile Beer Stroll on the same morning. The event centers on running and local beer, with finishers receiving a shirt, a Key to Beer City medal, a custom tasting glass, and unlimited tastings until noon from Santa Rosa and Sonoma County brewers.
The longer races follow the Santa Rosa Creek, showcasing a less-traveled section of the city, while the Beer Stroll remains near A Place to Play. Following the main races, the Beat the Beast Beer Mile challenges runners against a Beer City Beast; if caught, the runner is eliminated. The afternoon continues at Moonlight Brewing with the Shindig, featuring music by School of Rock Santa Rosa, food trucks, games, and a first beer included with entry. The Beermazing Race introduces a pub-challenge element, sending teams to visit five brewers between early and late afternoon, with limited capacity noted by organizers as a reason for potential sell-outs.
Victory 2027
Victory begins at the historic Craneway Pavilion in Richmond, California, sending runners onto the Richmond Bay Trail along San Francisco Bay. The series includes a half marathon, 10k, and 5k, allowing participants to select anything from a short bayfront run to a longer, flat road course. The courses are flat and fast, suitable for beginners and those aiming for a personal record.
The route follows the San Francisco Bay Trail, offering open views across the bay toward the Golden Gate Bridge, the Bay Bridge, and Mt. Tamalpais. The race name references Richmond’s World War II home front history, when hundreds of ships, including Victory ships, were built in the area, and the nearby Ford assembly plant shifted from car production to military vehicles. Runners can also combine this with the Breeze to Victory race for the B2V Double, receiving a combined “mega medal” with a special middle piece for completing both events.
Zoom San Francisco
Zoom San Francisco begins and ends at East Beach in the Presidio, with all distances heading west along the Golden Gate Promenade. This trail running event offers a 5K, 10K, half marathon, a short sprint, and a free 50-yard kids' dash for very young children. The race is included in Zoom Running Events' coastal calendar, featuring over 20 trail races along the California and Oregon coasts annually. Fields typically range from small to mid-sized, around 100 to 500 participants, with routes utilizing park paths and coastal trails instead of closed city streets.
The 5K route ascends the Battery East trail towards the Golden Gate Bridge before returning to East Beach. The 10K and half marathon proceed under the bridge, following the Coastal Trail towards Baker Beach, and traverse the Presidio and Fort Point area. The 10K turnaround is at the Baker Beach aid station, while the half marathon continues through Seacliff to Lands End, with its turnaround overlooking the Sutro Baths. Runners are treated to views of the bridge, the Pacific Ocean, and the Marin Headlands, though the course's tougher coastal terrain positions it more as a trail race than a flat road run. Distances are measured using a Rolatape surveyor's wheel, and youth pricing offers accessibility for families in the shorter races.

About Half Marathon races in Santa Rosa-Petaluma
Santa Rosa-Petaluma Training Ground
Santa Rosa-Petaluma 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.
Locals run Santa Rosa-Petaluma like a big mixed-surface playground. You can run an 8-mile loop around Kelly Pond. Annadel State Park, Spring Lake, Foothill Regional Park, Hood Mountain Regional Park, and Helen Putnam Park handle singletrack, rollers, and harder weekend vert. Empire Runners Club anchors the scene with the Grand Prix Series, Ilsanjo Classic, Annadel Loop, Valley Ford Relay, and Bob Shor Summer Track Series. Fleet Feet Santa Rosa and Heart and Sole Sports keep weekday routes moving from places like Franklin Park and Doyal Park.
Locals ride with Santa Rosa Cycling Club and Petaluma Cycling Club when they want base miles, pacelines, or a proper suffer day. The route runs 9 km from Walnut Park and gains 505 meters, so it feels honest without turning epic. Spring Hill-Chileno Valley stays classic, and the 30-mile loop out of Petaluma is even better since Spring Hill Rd was repaved in 2022. The climbs sit west on Wilson Hill, Marshall Wall, Coleman Valley Road, and Sweetwater Springs Road, while Cavedale, Mt Veeder, The Geysers, and King Ridge bring the hard stuff. Wine Country Century, Giro Bello, The Terrible Two, and Red Peleton TNT Criterium give the calendar real anchors.
Spring, Summer, and Fall give locals the best training window. Summer brings The Big Run Presented by Brooks and Fleet Feet Santa Rosa, Sebastopol Solstice Summer 5k! at Ragle Ranch Park, and Empire Runners Club’s Bob Shor Summer Track Series, so intervals and social miles both stay easy to find. Cyclists stack Z2 on Windsor Plain, Dry Creek Valley & Alexander Valley, Valley of the Moon, and Spring Hill-Chileno Valley before pushing west for coastal hills. Winter shifts runners toward Santa Rosa Turkey Trot, Beer City Half™ Santa Rosa, Resolution Run, and The Last 10k and Final 2-Mile. Riders keep fitness on the flatter south-side paved paths and frontage road system.
