How the day is laid out

The swim is held in a lake. An average of 21 °C is close to the threshold where wetsuit rules start to tighten. Plan for both answers and check the call on race morning.

The bike leg is labelled hilly.

The run is labelled hilly.

A hilly bike followed by a hilly run is the hardest combination on the calendar. The bike leg costs more than its distance suggests, and the run asks for what is left afterwards.

Expect air between 12 °C and 21 °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.
