How the day is laid out

The swim is held in the ocean. An average of 20 °C sits in the range where a wetsuit is both allowed and worth wearing for nearly everyone.

The bike leg is labelled rolling.

The run is labelled flat, over 4 laps.

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

Expect air between 18 °C and 30 °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.

Cut-offs and the swim finish

The swim starts on the Grande Plage and ends in the Vendée Globe channel, with a cut-off of 2 h 20. Swim and bike must be done within 10 h 30, with clock-time checks at km 90 (2.35 pm) and km 157 (5.30 pm). The organiser describes the bike as rolling but demanding, with many restarts.

The run is four loops from the Remblai to the Lac de Tanchet and the Puits d'Enfer, finishing on the Place du Palais de Justice. ironman.com gives 21 °C measured in the water in 2025, within the IRONMAN wetsuit limit of 24.5 °C, and a high of 35 °C on race day in 2026.
