ULTRASWIM IBIZA 2026 — Ultra & Mini

In 1159, a fleet from the Kingdom of Sicily descended upon Ibiza in a brutal Norman sack that left the population decimated and the island’s defenses in ruins. Centuries later, the same stretch of Mediterranean water that witnessed such turmoil serves as the arena for the UltraSwim Ibiza-Formentera, a 30km crossing that demands as much strategic endurance as the historical naval maneuvers that once dictated the fate of the Pityusic Islands. While modern swimmers do not face the threat of conquest, they must contend with the rigorous demands of the channel, including a strict 3km/h pace requirement enforced by mandatory check-in points at Cap des Librell, the 15km mark, and the passage between the islets of S'espardell and S'espardello.

Navigating the crossing

Long-distance swimmers have long been drawn to these currents, following the wake of pioneers like David Meca, who completed a 129km non-stop swim from the Spanish mainland to the island. Juan José Serra Boned, an Ibiza local, cemented his own place in regional lore by completing the 88km stretch from Jávea in under 38 hours. Participants in the 2026 edition, scheduled for May 30, will find themselves navigating a marine landscape dominated by Posidonia oceanica. This seagrass meadow, a UNESCO World Heritage site, is essential to the clarity of the water and the health of the local ecosystem. As you push toward Formentera, the silhouette of the Renaissance walls of Ibiza Town remains a constant, imposing landmark visible from the water, contrasting with the ancient Punic tombs of the Puig des Molins necropolis nearby.

Race day logistics

The logistics of a 30km open water event are substantial, explaining the necessity of a dedicated support boat and skipper for every athlete, which are included in the registration. This organizational complexity ensures safety across the unpredictable channel. Those seeking a shorter challenge often look to the Mini Ultraswim Ibiza, which shares the same coastal waters, while others competing in the XXVIII Cto España AA OPEN will experience the area just weeks prior. With three dedicated nutrition stations along the 30km route, the event is a test of sustained effort, culminating on the sands of Es Pujols. The finality of the journey—receiving the finisher medal on the Formentera coastline—marks the end of a physical pursuit through one of the most storied maritime corridors in the Balearic archipelago.
