Recurring Half Marathon races near San Sebastián
Races that repeat — weekly, monthly or yearly
Flysch Trail Zumaia
The Flysch Trail Zumaia is a trail running event held in Zumaia, on Spain's Basque coast. Participants can choose between a 14 km route and a 24 km route. The shorter race offers a straightforward way to enjoy the local trails, while the longer race is designed around the distinctive cliffs of the coastline.
The 24 km course follows the high coastal cliffs for most of its length, with the terrain itself being the primary attraction, rather than urban environments or large venues. The event also directs spectators to optimal viewing spots, provides changing facilities, and shares practical travel and parking details for accessing Zumaia. Runners may use the occasion to explore the nearby Geoparkea area, with lodging and dining information available. The race documents its history through photo archives, news, and pre-event preparation sessions.
Rural Kutxa Semi-Marathon de San Sebastian
The Rural Kutxa Semi-Marathon de San Sebastian is a 21 km road race held in San Sebastian, Guipuzcoa, within the Spanish Basque Country. It takes place in October, beginning at City Hall, and attracts approximately 5,000 participants, offering a large-city half marathon atmosphere without being an overwhelming event.
The course remains entirely within the city limits, utilizing asphalt throughout, with no trail or rough terrain. Participants have 2 hours and 30 minutes to complete the race, emphasizing the need for training even for those focused on finishing. Ayad Lamdassem's course record of 1:02:48 indicates the high speed of the leading competitors.
Sorginen Lasterketa
Sorginen Lasterketa is a mountain race starting and finishing in Plaza de Axpe, Axpe, Atxondo, Bizkaia, at 9:00 AM. This Basque trail event is compact yet steep, offering a 21 km race with approximately 1,750 metres of climbing and an 11.7 km option with about 890 metres of ascent. Registration is limited to 350 participants. The main race includes four aid stations, is rated medium-to-high difficulty, and has a five-hour time limit.
The longer route ascends Anboto, a 1,331 m peak that defines the race's sharp mountain character. The shorter route reaches the Larrano area, around 980 m. The participants include both skilled mountain runners and regular trail runners. The 21 km race is part of the Durangal series. The event, now in its later editions, is a well-established fixture in the Basque trail running calendar, maintaining a community feel rather than a large-scale event atmosphere.
Roncesvalles-Zubiri
Eltxo Trail
Eltxo Trail is a mountain race held in Orendain, a small town in Gipuzkoa, Basque Country. It features a 21 km half-marathon-style trail route and a shorter 7.3 km option, with mixed team categories available for both distances. The local council, Orendaingo Udala, organizes the event, which has scheduled afternoon starts for the 21 km and 7.3 km races.
The routes traverse Orendain and the surrounding areas of Abaltzisketa, Gaintza, and Baliarrain, characterizing it as a rural Basque hill race. Previous editions featured 20 km and 5 km courses, indicating a consistent focus on mountain running with adjusted distances. A local market in the town center during the race offers participants and spectators a chance to engage with Orendain beyond the event itself.
Bilbao Night Running Fest
The Bilbao Night Running Fest guides participants through Bilbao after dark, beginning at San Mamés and concluding at the Guggenheim. The event features two options: a 21K half marathon and the 10K Pirate Race, catering to those seeking a substantial city run or a brief evening challenge.
The course follows a city circuit on major avenues, differing from a secluded out-and-back path. Pyrotechnics, live entertainment, and numerous onlookers contribute to a festive atmosphere, distinct from typical road races. The city's football stadium and art museum define the course's start and end points.
Txara Trail
Txara Trail is a mountain running event in Markina-Xemein, Bizkaia, offering two race distances: a 17.7 km “mountain half marathon” and the 10.5 km Txaramotx run. The longer race involves 1,150 m of climbing, making it much steeper than its distance suggests; the 10.5 km option includes 600 m of ascent. The longer race starts in the morning, followed shortly by the shorter race. Walkers begin earlier on the same 10.5 km and 17.7 km routes.
The event is part of the Bizkaia running calendar, attracting trail runners in the Basque Country seeking a challenging day in the hills around Markina-Xemein. The event also accommodates non-runners through walking options on the same two distances. Prizes are locally focused: winners receive a Basque cap and baskets of local products, with cash awards for the top finishers in the longer race and local-product baskets for the first local finishers. Practical arrangements include parking, showers, and announced route adjustments near the start and finish areas.
Arrankudiaga-Zollo Trail Lasterketa
Semi-Marathon du Pays-Basque Donibane Hondarribia
The Semi-Marathon du Pays-Basque Donibane Hondarribia is a 21.097 km half marathon held each October, starting in Donibane Lohizune (Saint-Jean-de-Luz) and finishing in Hondarribia, on the Spanish side of the Basque Country. Its main draw is the border crossing: runners begin in France and end in Euskadi, with a course approved by both French and Spanish athletics federations.
The route goes through Saint-Jean-de-Luz, Ciboure, Hendaye, and Fontarrabie before concluding in Hondarribia. The race is organized by the club Ur J, requires a medical certificate from participants, and provides each runner with a bib printed with their name. A portion of the race's income supports social causes, and the event causes traffic disruptions in several Basque Country municipalities on race day.
Las Murallas de Pamplona
Las Murallas de Pamplona is a night running series in Pamplona, Navarre, Spain, held every year since 2013. Its name comes straight from the route: runners follow almost the whole line of the city’s old defensive walls, including the Citadel. The main race menu is simple: Fortín is 6 km, Ciudadela is 10 km, and Murallas is 15 km, though the longest option has used 18 km and 20 km routes in earlier editions. The event is organized by Club Kirol Bat Triatloi Taldea, and the city center closes to traffic while the races are on.
The course gives the race a very Pamplona-specific shape, passing places such as the Puerta del Socorro at the Citadel instead of using a generic road loop. It is a popular race with serious numbers: some editions have drawn more than 3,000 runners, and one came close to 4,000. A children’s race was added after the first few editions, with part of its entry money going to charities such as the Bone Marrow Donors Association of Navarre and UNHCR. The adult races award trophies to the top three finishers in each category, while the low entry fees and multiple distances make the night open to both casual runners and people chasing a place.
Hendaia trail - Hendaye
Hendaia Trail begins in Hendaye, a town in the Pyrénées-Atlantiques located at the far southwestern edge of the French coast. Situated in the heart of the Basque Country, it is the last coastal town before Spain, giving the race the distinct setting of a border town between the Atlantic Ocean and the mountains. This trail-running event offers two race options, designed for runners seeking a challenge beyond a flat road course.
The routes guide participants up to the heights overlooking Hendaye and return through the town’s streets, incorporating flat sections alongside more demanding terrain. The course crosses both beach and mountain landscapes, and it winds through an area rich in Basque identity, diverging from a purely wild path. While the Basque Country hosts trail races year-round, this event was established as Hendaye’s inaugural nature trail race.
Skyrhune - Ascain
Skyrhune is a 21 km mountain trail race starting in Ascain, Basque Country, featuring 1,700 m of elevation gain on a compact, demanding course. Participants will ascend the slopes of La Rhune, focusing on steep climbs, rapid descents, and technical trail running over leisurely distances.
The race attracts trail runners from all over France, with only 500 spots available via lottery for its upcoming edition. The atmosphere in Ascain is notable, with one runner describing it as a race with significant atmosphere, commending the organization, and expressing regret that it concluded after ten editions. A shorter option, Skyrhune Ttiki, offers a different route within the same locale for those seeking a less demanding 21 km course.

About Half Marathon races in San Sebastián
Donostia Training Notes
San Sebastián hosts 26 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 the city by the water first. Paseo de la Concha gives you 7 km along the sea, and it feels like base miles with a view. Urgull gives you 2 km up to Castillo de la Mota when you want a short punch. Ulia gives you 8 km through Mount Ulia when singletrack legs matter. Monte Igueldo gives you 10 km with a real slope. Real Sociedad and CHH Txuri Urdin sit in the local club scene. Maratón de San Sebastián, Media Maratón de San Sebastián, 15 km Donostia - San Sebastián, and Behobia-San Sebastián are the anchor races.
Locals ride out from Donostia on bidegorris, and the city has 30 km of them. Vuelta Donostia gives you 50 km around the city with rural lanes, parks, forests, the Urumea River, Herrera docks, and Ulia cliffs. Leizarán and Plazaola Greenway, Ulzama and Basaburua valleys, and Bidasoa Greenway make good Z2 days. Mount Jaizkibel is where the climbing gets serious. The San Sebastián to Leitza stage covers 47 km and gains 710 meters. Clásica de San Sebastián is the anchor event, and BiziKrosa keeps the cyclocross crowd honest.
Summer gives Donostia its driest, sunniest training block. Locals use July and August for early runs on La Concha and steady rides before the beach crowds fill the day. August averages 22°C, so intervals still work if you start clean and keep the route simple. Mid-September to mid-November is the sweet spot for riding, with morning averages about 15 degrees and coastal roads quieter. January averages 8°C, and winter turns runs toward city loops, Urgull reps, and Ulia trail options. Cyclists keep base miles close, then head inland when the day opens.
