King of the Lake – Triathlon at the Attersee

King of the Lake on September 26, 2026, is one of the most beautiful and celebrated triathlon events in Austria — an Olympic-distance race (swim, cycle, run) that takes place entirely in and around the extraordinary landscape of the Attersee, one of the finest alpine lakes in Central Europe. Starting at 1pm, the course takes participants from an open-water swim in the famously clear waters of the Attersee through a cycling stage in the surrounding hills, and on to a run along the spectacular lakeshore to the finish line.

The Attersee is renowned throughout Austria for its exceptional water clarity and its deep, luminous blue-green colour — a result of the glacial geology and the purity of alpine inflows. Swimming across this remarkable body of water is an experience that stays with athletes long after they have crossed the finish. The cycling and running stages offer views that are equally spectacular, making King of the Lake one of those races where the route itself is part of the reward for every participant.

The Attersee has drawn artists, musicians, and nature lovers to its shores for generations — most famously Gustav Klimt, who spent many summers here and produced some of his finest landscape work on the lake. The combination of natural beauty, warm summer water, and easy accessibility has made the Attersee one of the most beloved summer destinations in the Salzkammergut, and the King of the Lake race captures all of that beauty in its course design.
