How the day is laid out

The swim is held in a river. At an average of 16 °C this is cold water. A wetsuit will be worn by almost everyone who is allowed one, and a swim shortened or cancelled for conditions is a real possibility at this end of the range.

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 8 °C and 20 °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.
