What this race demands

Alssundman demands disciplined pacing across three distinct disciplines over a standard 113-kilometer middle-distance triathlon format.

Aero Endurance

Sustaining a high output across the cycling and running segments requires strong aerobic capacity and muscular endurance.

Pacing Control

Managing effort across three continuous disciplines prevents early fatigue, particularly during the transition from the bike to the run.

A target intake of 60 to 90 grams of carbohydrates per hour is recommended to sustain energy levels across the middle-distance duration.
