What this race demands

This ultra-distance triathlon demands exceptional multi-sport endurance to complete a 4.0 km swim, 190 km bike, and 42.2 km run over an extended duration.

Extended Durability

Covering a total distance of 236 km across three distinct disciplines requires pacing control to sustain output over many hours of continuous exertion.

Cycling Endurance

The 190 km cycling leg represents the vast majority of the total distance, demanding sustained aerobic capacity and efficient position holding for hours in the saddle.

Run Execution on Fatigue

The concluding 42.2 km marathon requires the structural durability and neuromuscular resilience to run effectively after a massive prior swim and bike load.

Given the extreme duration of this event, athletes must consume 60 to 90 grams of carbohydrates per hour to maintain energy availability.
