XCIX Port de Tarragona

In 1641, the harbor of Tarragona became the site of a chaotic naval engagement during the Reapers' War, as Spanish galleys desperately fought to evade a French blockade by setting their own vessels ablaze to deny the enemy control. Today, the water beneath the port walls offers a much calmer experience for the athletes of the XCIX Port de Tarragona, an annual event hosted by the Reial Club Nàutic de Tarragona. Swimming here means navigating the same harbor that ancient geographers like Strabo once labeled 'alimenos'—or harborless—due to the challenging natural conditions that have tested mariners for millennia.

The conditions and the coast

As you sight your path, you will likely notice the Balcó del Mediterrani towering above the coastline, a landmark that has guided sailors toward this port for generations. The sea state is fundamentally shaped by the local wind patterns; while the cold, dry 'Mestral' (NW) wind can occasionally stir the surface, summer swimming is generally defined by a steady regime of coastal breezes. Swimmers should keep an eye on the horizon, as these thermal winds dictate the surface texture of the bay. For those looking to continue their season in the same region, the 11th Tarraco Open Waters offers a different perspective on these waters just a few weeks prior.

Navigating history

Beyond the buoys, the local landscape is marked by centuries of maritime defense. Along the coast, you can spot the legacy of the 16th and 17th-century piracy crisis, which saw the construction of defensive structures like the Torre de la Mora to watch for incoming corsair raids. The history of the area runs deep, and even if you are focused on your stroke, you are swimming in the shadow of the Roman amphitheatre, a structure that once housed the church of Santa Maria del Miracle. The event itself, held annually in September, provides a rare opportunity to traverse this historic harbor. Whether you choose the 1000m or 2000m distance, the experience is anchored in the same maritime culture that once produced the famous Chartreuse liqueur, which was distilled by monks within the city limits for much of the 20th century. While the nearby Port de Salou offers another point of entry into the Costa Daurada, the XCIX Port de Tarragona remains a central date for those who value the intersection of long-distance swimming and deep-rooted coastal history.

The oldest crossing in Spain

The Reial Club Nàutic de Tarragona — founded in 1878, the city's oldest sports club — organised the first harbour crossing in 1925, which makes this the oldest swim crossing still held in Spain. It has been tied to the September festivities of Santa Tecla, Tarragona's patron saint, ever since.
