How the day is laid out
The swim is held in the ocean, from a rolling start. An average of 29 °C is warm. Wetsuit use is commonly restricted above this point, and the swim becomes a question of heat more than of cold.
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 28 °C and 32 °C, the range the organiser publishes for 25 July 2027. A spread of 4 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.
