Travesía del Club Deportivo Bilbao

The waters off Playa de Górliz require a sharp focus on the local atmospheric rhythm. Swimmers here often encounter the 'sirimiri', a persistent and delicate drizzle that is as much a part of the local identity as the sea itself. The current here is influenced by the proximity to the Nervión estuary, which has undergone a profound transformation. Decades ago, industrial activity induced a state of anoxia that all but silenced the marine ecosystem; today, environmental recovery has brought back sole and crabs, creating a living backdrop for those crossing the stretch toward Muriola Beach.

Race day logistics

This annual tradition, organized by the Club Deportivo Bilbao, sees participants navigating toward the Astondo Pier after rounding offshore buoys. The 1,500m and 3,000m distances are designed to test endurance across the varied conditions of the Cantabrian coast. While the event maintains a traditional character, the logistics are streamlined for the modern swimmer, with comprehensive guidance provided in the official swimmer’s handbook. Those seeking a different pacing in the region may also look to the annual event in Santurtzi, which offers a distinct experience just a few weeks later.

A landscape of history

As you sight your path, the surrounding hills—such as Artxanda and Mount Avril—stand as silent witnesses to the 'botxo', the deep basin that cradles the city. These heights are not merely scenery; they contain archaeological sites dating back six millennia, representing the long-standing human connection to this terrain. Locals often refer to themselves as 'chimbos', a nod to the historical bird hunting traditions of the 19th century that once defined the interaction between the people and this environment. Whether you are navigating the offshore turn or pushing toward the finish at the Astondo Pier, the route is a direct engagement with the geography that has shaped Bilbao for generations.
