How the day is laid out

The swim is held in a river. An average of 26 °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.

The run is labelled flat.

A rolling bike ahead of a flat run keeps the climbing on the bike and lets the run settle into a rhythm.

Expect air between 17 °C and 29 °C on race day. A spread of 12 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.
