What this race demands

IRONMAN Kaernten-Klagenfurt demands sustained endurance across three consecutive disciplines over a 226.3 km distance with 1825 m of elevation gain.

Aero efficiency

The 226.3 km total distance requires maintaining an efficient aerodynamic position over many hours on the bike course through Carinthia.

Pacing discipline

With an elevation gain of 1825 m spread across the course, athletes must manage their energy output carefully during the swim, bike, and run to avoid late-race fatigue.

Run durability

The marathon-length run following the swim and bike demands robust muscular endurance to handle the transition and finish along the lake and through Klagenfurt.

Aim for 60 to 90 grams of carbohydrates per hour throughout the bike and run segments to sustain energy output across the long duration of the race.
