The Craon Natur'halles Trail begins and ends beneath the Halles in Craon. The event village and activities are located in this same covered central area. The main race day occurs on a Sunday in late October. The program features nature-trail distances: 33 km for participants over 20 years old, 16.5 km for participants over 18 years old, and youth races requiring parental authorization with separate starts for each age group.
The 33 km race starts first at 8 AM, followed by the 16.5 km race at 9 AM. Youth races begin later in the morning, and an 8.5 km walk starts at 10:10 AM. The walk is organized on-site only and benefits Club des Roses. A corporate challenge allows mixed or single-gender teams of three from the same company to compete together. Online registration is open for the running events, with 650 bibs available. The series is approaching its 15th edition.
