ALSTOM Atlantic Races

Les courses Atlantiques d'ALSTOM is an annual coastal running event held around Aytré in Charente‑Maritime. The 2026 edition (the organiser lists it as the 39ᵉ édition) brings multiple nature/trail distances on scenic littoral routes offering panoramas towards Île de Ré and Île d'Oléron. The races are organised by ACF Alstom and are presented as family‑friendly community events with a children’s obstacle activity alongside the adult races.

On Sunday 31 May 2026 the event gathers several formats with a duo relay option and on‑site/preceding bib collection (Saturday 30 May 14:00–18:00 and Sunday 31 May 07:30–09:00 as listed by the organiser). Participation is limited (the organiser page states a cap of 999 participants) and the event encourages eco‑friendly practices such as bringing a reusable cup for aid stations. Registration is handled via the organiser's links and the event blog; participants are advised to consult the official organiser pages for final details and maps.
