IRONMAN Kaernten-Klagenfurt, Austria
The Carinthian full distance starts with 3.8 km in the Wörthersee, which is one of the warmer race lakes in Europe. That is pleasant and it is also a variable: in a hot June the water can climb towards the limit where wetsuits stop being allowed, and a non-wetsuit 3.8 km is a different swim from the one most age-groupers have trained.
The 180 km bike is hilly, out through Carinthia on climbs that are steady rather than alpine, and the 42.2 km run comes back flat along the lakeshore and through Klagenfurt with dense support on the town sections.
The structure suits a specific athlete: a strong climber who can still run flat off a hard bike. If your strength is holding watts on flat roads, you will lose time in the middle of the day and not get it back.
Mid-June here can be genuinely hot. Treat the lakeside marathon as a heat run.
