How the day is laid out

The swim is held in a lake. An average of 23 °C is close to the threshold where wetsuit rules start to tighten. Plan for both answers and check the call on race morning.

The bike leg is labelled rolling.

The run is labelled flat.

A rolling bike ahead of a flat run keeps the climbing on the bike and lets the run settle into a rhythm.

Expect air between 12 °C and 24 °C on race day. A spread of 12 degrees across the day matters as much as the peak, because what you wear at the swim exit is rarely what you want at the far end of the bike.

The water measured on race day

ironman.com publishes the Wörthersee temperature measured on race day: 19 °C in 2024, 22 °C in 2025 and 21 °C in 2026, each below the average shown on this page. Under IRONMAN rules, age-group athletes may wear a wetsuit up to 24.5 °C, so it was within the rules at each of these editions.

The swim ends in the Lendkanal, a canal lined with spectators. The bike has steep climbs and descents through Carinthia. The run is flat, through the centre of Klagenfurt and along the lake towards Krumpendorf. Race-day air peaked at 16 °C in 2024 and 30 °C in 2025.
