La Ronde du Hibou is an urban trail run held in late March in Le Plessis-Robinson, a town in Hauts-de-Seine located approximately 15 minutes from Paris. Organized by the Plessis-Robinson Athletic Club, the event maintains a local character and prioritizes its charitable cause.
It is not a timed race, and its proceeds benefit Marie Lannelongue Hospital, which specializes in treating heart and lung conditions. The event offers routes for children and juniors, alongside adult trail distances of approximately 1.5 km, 7 km, and 16 km, varying by edition.
