How the day is laid out

The swim is held in a reservoir. 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 rolling.

The run is labelled flat.

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 9 °C and 19 °C on race day. A spread of 10 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.

A swim in the Grand Canal, and a 2027 date to come

The swim is one loop of 1.9 km in the Grand Canal of the château de Versailles, and the finish faces the château on the Avenue de Paris. The organiser gives 1 h 09 min 59 s for the swim, 5 h 29 min 59 s for swim and bike, and 8 h 29 min 59 s in all.

The October 2026 race has taken place. On 16 October 2026 the race page announced registration as opening soon, without a 2027 date.
