How the day is laid out
The swim is held in a bay, over 2 loops. An average of 21 °C is close to the threshold where wetsuit rules start to tighten. Plan for both answers and check the call on race morning.
The bike leg is labelled flat and runs over 2 loops. No elevation figure is published for it on the organiser's pages, so this site holds none.
The run is labelled flat, over 4 laps.
A flat bike followed by a flat run is the most predictable combination on the calendar. It removes climbing and the descents that come with it, so power output stays constant for the whole bike leg and wind becomes the main variable.
Expect air between 16 °C and 23 °C, the range the organiser publishes for 6 December 2026. A spread of 7 degrees across the day matters as much as the peak, because what you wear at the swim exit is rarely what you want at the far end of the bike.
