How the day is laid out
The swim is held in a bay. An average of 20 °C sits in the range where a wetsuit is both allowed and worth wearing for nearly everyone.
The bike leg is labelled rolling. No elevation figure is published for it on the organiser's pages, so this site holds none.
The run is labelled rolling.
A rolling bike and a rolling run, as the organiser labels them. These are words, and no elevation figure is published to put a number on them.
Expect air between 19 °C and 26 °C, the range the organiser publishes for 31 January 2027. 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.
