How the day is laid out

The swim is held in the sea. An average of 24 °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 hilly.

The run is labelled flat.

A hilly bike ahead of a flat run puts the day's decision early: what you spend on the climbs is what the run will not have.

Expect air between 18 °C and 26 °C on race day. A spread of 8 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.
