La Crépynoise is a road-running event in Crépy-en-Valois, Oise, northern France, held in early October during Pink October. Organized by USC Athlétisme, it offers adults a 5 km or 10 km mixed race, and a 7 km walk for those preferring not to race. Younger runners are included with children’s races from an eight-minute run for the youngest category to 1.5 km and 3 km for older children.
The routes follow the streets of Crépy-en-Valois, guiding participants through the town’s scenic areas. The 7 km walk has 750 places, while the 5 km and 10 km races each have 250 spots, with over 100 runners in the previous edition. A family mountain-bike outing is also part of the weekend, creating a local sports gathering atmosphere. The event's primary goal is fundraising, with all proceeds supporting the Oise League Against Breast Cancer.
