Les Andelys (at the foot of Château Gaillard), 27700 Les Andelys, France
The Trail du Château Gaillard (French name retained) takes place on 28 June 2026 in Les Andelys, Normandy, beneath the Château Gaillard fortress. This single-day trail festival offers multiple distances for runners and a timed nordic-walking option, with routes that thread cliffs, riverside paths and wooded sections. The event is presented by the local organising team and links online registration to an external Njuko page; a downloadable règlement / race regulations document is also published from the event site.
The courses are noted for significant elevation and technical trail sections, with aid stations and on-course support for competitors. Route maps and traces are published on the official event pages and associated distance pages, and bib pickup and safety requirements are referenced in the event information. Participants should consult the organiser's règlement and the official event pages for final start lists, kit obligations and any last-minute updates.
