How the day is laid out

The swim is held in a lake. 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 rolling. It climbs about 427 m.

The run is labelled rolling.

A rolling bike and a rolling run keep the effort changing all day, so pace by feel rather than by speed.

Expect air between 17 °C and 28 °C on race day. A spread of 11 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.
