How the day is laid out

The swim is held in a lake, from a self-seeded start. 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 flat. It climbs about 250 m.

The run is labelled rolling.

A flat bike ahead of a rolling run is a common pairing. It rewards a steady bike and makes a bike ridden too hard show up on the run.

Expect air between 19 °C and 27 °C on race day. A spread of 8 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.
