La Neuvilloise is an untimed trail run or walk in La Neuville-sur-Ressons, organized as part of Octobre Rose. Participants choose 5 km, 10 km, or 15 km, suitable for walkers, casual runners, and those seeking a longer trail outing.
The event raises money for the Ligue contre le Cancer, with a clear charity purpose rather than a race-clock focus. Now in its 18th edition, its 4,142 reviews indicate a well-attended local event with a large base of past participants.
