OWT Szentendre–Budakalász Dunaátúszás 2026

The 5,000-meter course spans the Danube from the Postás beach in Szentendre to the shoreline near the Ebihal buffet in Budakalász. Scheduled for July 5, 2026, the event requires participants to navigate a river current consistently moving at 4-5 km/h, supported by a full shipping closure on the waterway. Organizing bodies—the Open Water Tournament team and the Pest County Search and Rescue Service—manage the logistics, including transport buses to return swimmers to the race center after the finish, where food such as traditional bread with fat is served. The entry fee is 16,000 HUF.

The river landscape

As you progress downstream, the water mirrors a history shaped by defensive strategy and migration. You swim past the historical site of Ulcisia Castra, the 'Wolf Castle' that once served as a pivotal Roman military outpost on the Danube limes, visited by emperors like Septimius Severus. The current carries you alongside the silhouette of the town, where the 18th-century influence of the Great Serbian Migration remains evident in the architecture. You can identify the skyline by the seven towers, most notably the 48-meter bell tower of the Belgrade Cathedral, which served as a landmark for merchant families fleeing the conflicts of the 17th century.

Historical currents

To your right, the slopes of Szamárhegy, or Donkey Mountain, rise above the water, marking the area where Dalmatian settlers established their community centuries ago. The river itself serves as a vital ecological artery, as the nearby Szentendre Island provides the primary fresh water supply for Budapest. While you navigate the main channel, the proximity of the banks recalls an era when the Bükkös Brook, feeding into the river, powered the medieval water mills that drove local ship and wagon building. This swim utilizes the natural flow of the Danube while maintaining a constant connection to the settlements that have defined these banks since Roman times.
