L'Orrygeoise 2026

L'Orrygeoise is a trail-running event held in Orry-la-Ville, a commune in the Oise department north of Paris, situated on the southeastern edge of the Forest of Chantilly. It takes place in September and features several formats: long trail options, a 10 km race and walk, 5 km and 2.5 km races, and races for children. The courses remain entirely off-road, distinguishing the event from a city road race despite its proximity to the capital. The longest trail is 42 km with 350 m of elevation gain. The shorter races and walk accommodate families, beginners, and those seeking a less demanding distance. The event includes timing, aid stations, and sanitary facilities. A portion of the proceeds benefits the SPA Foundation, France's animal protection society.
