Achensee long-distance swim event
The long-distance swimming competition will take place on 5 July 2026 between the mountains and the lake. Distances range from 250 metres to the ultimate challenge of nine kilometres across Tirol's largest lake. With this event, Achensee takes its place alongside renowned Alpine lakes like Tegernsee and Chiemsee - standing out in particular for offering the longest distance in the "arena Alpen Open Water Cup" series.

The full 9 kilometres
Yes, you've read that right! It’s the longest distance and a unique chance to swim the full 9-kilometre length of Lake Achensee. This "supreme discipline" from the bathing beach Achensee Nord (Strandbad Achenkirch) to the SEE-Bad at the Atoll Achensee is also a point-value race for the biggest open water swimming cup in the German-speaking world. The "arena Alpen Open Water Cup" is a series of swimming competitions with a common points-based system.
For children, youngsters and amateur swimmers
In addition to the long distance of nine kilometres, the event will also include shorter distance races. Swimmers can choose from distances of 5 kilometres (middle distance) or 2.5 kilometres (short distance). For children, youngsters and amateur swimmers, there are races over 500 and 250 metres. The start and finish of each race is the SEE-Bad at the Atoll Achensee in Maurach.
