How the day is laid out

The swim is held in the ocean. An average of 23 °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 rolling. It climbs about 857 m.

The run is labelled flat. It has 36 m of elevation gain.

A rolling bike ahead of a flat run keeps the climbing on the bike and lets the run settle into a rhythm.

The overall cut-off for this race is 8 h 30.

Expect air between 12 °C and 18 °C on race day. A spread of 6 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.
