How the day is laid out

The swim is held in a river. An average of 19 °C sits in the range where a wetsuit is both allowed and worth wearing for nearly everyone.

The bike leg is labelled flat.

The run is labelled flat.

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 13 °C and 22 °C on race day. A spread of 9 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.
