Wörthersee Marathon 2026

Run The Lake is a 42.195 km marathon starting and finishing at Strandbad Klagenfurt in Austria. The race circles Lake Wörthersee, making the lake the main structure of the day, not just a backdrop. The course changes noticeably halfway through. The first 21 km follow the southern shore toward Velden and include hills; the second half turns flatter and faster. The event permits running and walking late in the day, with participants following traffic rules and a finish deadline in the evening.
