Les Machines de l’Île and Parc des Expositions de La Beaujoire, Nantes, France
The Abalone Marathon de Nantes 2026 is a two‑day urban running weekend held in Nantes on 25–26 April 2026, presenting multiple distances under the same brand. The programme for the weekend includes the Marathon, the Semi‑marathon, the Marathon Relais Entreprises Harmonie Mutuelle and the nocturnal 10 km Les Foulées de l'Éléphant, with start and finish areas centred on Les Machines de l’Île and the Parc des Expositions de La Beaujoire. The official site (Abalone Marathon de Nantes) provides the Règlement and a Guide Coureur with detailed route and logistical information available on the event pages.
The races run on largely urban, monument‑rich routes that pass Nantes landmarks including the Cathédrale and the Château des Ducs de Bretagne and feature the signature Erdre floating crossing. The 10 km is promoted as a festive night race with music at the Nefs des Machines de l’Île, while the relay is a four‑person corporate format on the same marathon course. The 2026 edition is noted on the organiser site as highly in demand, with organisers reporting that the events for 2026 are full.
