From Les Sables d'Olonne to the pinnacle of triathlon
Since its first edition in 2019, the Ironman 70.3 Les Sables d'Olonne – consisting of a 1.9 km swim, a 90 km bike ride, and a 21.1 km run – has established itself as one of the most popular triathlons in France. In 2024, the event confirmed its reputation by once again becoming one of the most anticipated Half-Ironman races on the calendar. But in 2025, the organizers decided to take things to the next level with a full Ironman version. .
2026: Back to basics
After an ambitious 2025 edition, the event returns to its original format. The 2026 edition of the Ironman 70.3 Les Sables d'Olonne is scheduled for Sunday, July 5, 2026. .
The route
The route, true to its roots, still offers:
- Swimming (1.9 km) : start from the Grande Plage, with an emblematic climb of the mythical Vendée Globe channel.
- Cycling (90 km) : a loop through the Olonne forest, the salt marshes, and the surrounding towns. A rolling but demanding route, with some false flats and a moderate elevation gain of approximately 600 m.
- Running race (21.1 km) : two loops on the Remblai, along the Tanchet lake, with a possible passage on the beach, under notable popular support.
The legendary atmosphere of this event remains a strong point, with an organization praised for its setting, the enthusiasm of the public, and the spectacular dimension offered to spectators.
In short : the 2026 Ironman 70.3 Les Sables d'Olonne marks a triumphant return to the already iconic Half-Ironman format. The date and course have been announced, the excitement is palpable – and the event's reputation has never been stronger. The key takeaway: be ready when registration reopens if you're aiming for 2027!
