Official event pageWhat this race demands
This middle distance triathlon demands sustained multi-sport endurance across a 1900m swim, a hilly 92km bike leg with 940m of climbing, and a 21km run. Athletes must manage pacing and nutrition carefully to handle the cumulative fatigue of a half-distance effort.
Hilly bike power
The 92km bike course features 940m of elevation gain, requiring sustained climbing ability and efficient pacing to preserve the legs for the upcoming run.
Run durability
Following the swim and the hilly bike leg, athletes face a standard 21km half-marathon run that requires deep muscular durability to maintain forward progress under cumulative fatigue.
Transition execution
The multi-sport format of an official middle distance championship requires smooth transitions between swimming, cycling, and running to prevent energy leaks.
Aim for 60 to 90 grams of carbohydrates per hour throughout the bike and run legs to sustain energy output across an expected duration of roughly 4 to 7 hours.
