Official event pageWhat this race demands
IRONMAN 70.3 Geelong demands sustained output across a 113.1-kilometer multisport distance, requiring efficient pacing from the Corio Bay swim through the multi-lap bike course and waterfront run.
Aero Durability
The multi-lap bike course through countryside and urban terrain requires maintaining an aerodynamic position for an extended duration without compromising subsequent running mechanics.
Pacing Control
Managing energy expenditure across three distinct disciplines over the 113.1-kilometer total distance is critical to prevent late-race fade during the run along the Geelong waterfront.
Multisport Transition
The transition from the calm protected waters of Corio Bay to the bike leg demands quick physiological adjustment to establish an immediate, steady rhythm.
Given the duration of a 70.3-distance triathlon, athletes should target 60 to 90 grams of carbohydrates per hour throughout the bike and run legs to maintain glycogen stores.

Progressive overload: training load climbs in waves, with harder weeks stacked on the base and planned recovery weeks that let the gains land.
