The IRONMAN group has officially confirmed that the city of Versailles will host its inaugural IRONMAN 70.3 triathlon on Sunday, July 12, 2026. This “half-distance” triathlon (113 km total) offers a once-in-a-lifetime opportunity for athletes to swim, bike, and run through the historic grounds of the Sun King’s royal estate, just 15 minutes by train from Paris.
With the French triathlon market currently in a state of “ebullition”—now the second-largest in Europe—and all existing 2026 French races having sold out by the end of 2025, this new event is expected to be highly coveted.

The Course: A Royal Tour of the Yvelines
The race is designed to be as culturally rich as it is physically demanding, utilizing the Baroque architecture and geometric gardens of the Palace of Versailles.
- Swim (1.9 km): The race begins in the Pièce d’eau des Suisses (The Pond of the Swiss), a 13-hectare basin constructed in the late 17th century. Athletes will swim with the majestic Château de Versailles as their backdrop.
- Bike (90 km): A one-loop, rolling course takes competitors through the City of Versailles and into the picturesque Chevreuse Valley, passing through several charming French villages.
- Run (21.1 km): The half marathon returns to the palace grounds, winding through the Potager du Roi (King’s Kitchen Garden) and historic streets.
- Finish Line: The final stretch leads to the Avenue de Paris, where the finish line is positioned directly in front of the Palace.

The Road to the 2026 World Championships
The addition of Versailles is a strategic move for athletes aiming for the 2026 IRONMAN 70.3 World Championship, which will also be held in France—specifically in Nice on September 12–13, 2026.
Because Versailles takes place late in the qualifying cycle (July 2026), some forum experts suggest it may be a high-slot race (potentially up to 100 slots) as a host-country qualifier. This makes it a prime opportunity for athletes to secure a spot for the World Championships on home soil.
Community and Sustainability
The city of Versailles is heavily supporting the event, negotiating an exemption from €275,000 in registration fees and providing direct financial support of €8,000 to €10,000 to the local “Versailles Triathlon” club. The municipality also emphasizes that the race aligns with its goals for sustainable development, using the heritage sites as a model for “putting nature back at the heart of the city”.
