La Domaniale Trail

La Domaniale - Trail - Domaine national de Saint Cloud is a one-day charity trail event held in the Domaine national de Saint-Cloud. The event offers three distances—8 km (marche), 12 km (course) and 20 km (course)—that showcase the park's landscape and trail paths. The outing on 4 October 2026 is presented by the local club and aimed at walkers and runners of varying abilities. The organiser promotes limited entry to preserve the experience and the natural setting.

The event is organised by volunteers from UAS Saint-Cloud and supports the Fondation Arthritis, with €1 from each bib and a share of any surplus donated to the charity. Registration opens in mid-April with early access for returning and pre-registered participants, and general registration thereafter; only 1,200 bibs are available for 2026. The official site provides the registration form and a dedicated contact email for inscriptions. Practical details such as official start times, course maps and aid station information are not provided on the event page and are expected to be published closer to the date.
