What this race demands
IRONSTAR Olympic Sirius requires an athlete to sustain high aerobic output across a standard Olympic-distance triathlon format of a 1.5 km swim, 40 km bike, and 10 km run.
Multidisciplinary Endurance
The event demands continuous aerobic and muscular stamina to transition effectively from the swim to the bike, and finally to a 10 km run without significant pacing fade.
Threshold Sustained Power
The 40 km bike segment requires maintaining a steady, high-percentage threshold effort to preserve running legs for the concluding 10 km.
Given an expected duration generally exceeding two hours for most participants, athletes should plan for an intake of 60 to 90 grams of carbohydrates per hour, primarily consumed during the bike leg.
