MARNATON eDreams Ibiza by Baleària

On October 10, 2026, the Mediterranean waters off Ibiza will host three competitive distances: 2000m, 4000m, and 8000m. This annual event attracts participants to the Pityusic Islands, requiring a registration fee between 45 and 75 EUR, which covers the timing chip, a swim cap, and a finisher medal. Swimmers should prepare for a salt-water environment where water temperatures typically remain mild through early autumn. The organization coordinates maritime logistics and safety protocols to manage the specific conditions of this coastline, ensuring a controlled environment for all waves.

Historical markers and coastal landmarks

Navigating the coastal currents provides a unique perspective on the island's layered past. As you swim, the Dalt Vila Renaissance walls remain visible from the water, an intact fortification system dating back to the 16th century. Further along the trajectory, the Phoenician settlement of Sa Caleta stands as a testament to early Mediterranean trade routes, founded in the 7th century BC. You may also catch sight of the Sagrat Cor de Jesus monument, a 23-meter statue standing on a northern hill that mimics the silhouette of coastal sentinels. For those looking for a different challenge, OceanMan Ibiza takes place just six days later, offering an alternative pacing for the season. History in these waters is not purely static; in 1937, the port of Ibiza became the site of the bombardment of the German battleship Deutschland, a naval incident during the Spanish Civil War that altered the conflict's regional dynamics.

Marine environment and conditions

The sea state around Ibiza is influenced by the Posidonia oceanica seagrass meadows, which clarify the water and support the local marine ecosystem. While the coastline is generally accessible, areas like Agua Blanca are characterized by stronger breezes that create white-capped waves, a natural phenomenon that dictates the rhythm of the swim. The island's geography, dominated by the 475-meter Sa Talaiassa peak, creates distinct wind patterns that swimmers learn to navigate during the long-distance crossings. Beyond the race course, the silhouette of the Es Vedrà islet remains a constant, rising 382 meters from the sea floor as a defining feature of the horizon. Success in these waters relies on understanding these local wind and current cycles, which have been documented by generations of island-born swimmers like Juan José Serra Boned, who completed the 88 km crossing to the mainland.
