Wörthersee Crossing powered by Alpen Adria Swim Cup

About the Event

The Wörthersee Crossing powered by Alpen Adria Swim Cup takes place on September 12, 2026, in Klagenfurt, offering swimmers a variety of distances to choose from. Participants can dive into the Pörtschach course for a challenging 10 km swim or tackle the full Wörthersee Umrundung at an impressive 34 km with boat support. Additionally, there are shorter options like the 2.5 km Kraftwerk and even special categories for kids, including a 250 m race and a dedicated event for young all-stars covering 500 meters.
For those looking for something in between, distances of 17.5 km to Klagenfurt or a more manageable 5 km at Bad Saag are also available.
