10K races near Sestao

The 10K de Castro Urdiales is a 10-kilometre road race held in Castro Urdiales, organized by Club Correcastro. Runners begin at Parque Amestoy in the morning. The event attracts over 500 athletes, and the competition at the front can be intense. In one past edition, four men reached the halfway point together, with the winner decided in the final kilometre. The course is exposed to the elements, and heat and strong south winds have impacted runners in previous races. A tradition involves inviting a well-known athlete as the event patron; double world marathon champion Abel Anton served in this capacity and received a trophy from Club Correcastro president Jose Mari Uncilla. Olympic medalist Jose Manuel Abascal was the announcer. Andoni Acebedo won the race, breaking away with one kilometre remaining to finish in 31:56, closely followed by Rodrigo Senovilla in 31:58 and Diego Pascual in 32:03.

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 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.

Bilboko Herri Krosa is a 10-kilometre popular run through Bilbao, founded on the idea that participation is as important as speed. Approximately 10,000 people participate annually, with a field comprising sports enthusiasts of various ages, not solely dedicated racers. The course is moderate, utilizing the city’s main thoroughfares, making the race suitable for runners of widely differing experience levels. Its most notable tradition involves honoring the first and last finishers equally, fostering a relaxed, community-oriented atmosphere.

Etxebarri Xtreme is a trail-running series in Bizkaia featuring a 30K race, a 10K race, a canicross event, and a martxa walk. It uses off-road routes, providing separate paths for runners, walkers, and dog-and-runner teams within the same event. The 30K is the main challenge, with the 10K offering a shorter race on similar terrain. The canicross race distinguishes the series from typical trail events, and the martxa allows participation for those seeking the mountain-route experience without competitive racing. The organizers describe the routes as spectacular, focusing on atmosphere and event coordination.

Gabonetako Krosa is a 5 km race held annually in Irún as the year concludes. Organized by Super Amara Bidasoa Atletiko Taldea, its purpose is to encourage activity before the year ends. The primary race begins on Paseo Colón, crossing the city's downtown streets. It features general men's and women's categories, alongside a team-based Carrera por Cuadri category. The event also hosts children's races in the Luis Mariano vicinity, welcoming participants as young as one year old. Runners have the option to contribute any amount to the race's designated charity. All participants are entered into a prize drawing, with awards presented on the Luis Mariano pedestrian stage following the races.
