Les Foulées de la Liberté and their 4,000 children open the festivities for a weekend of sport and conviviality. Organised jointly with the City of Caen's Sports Department, the event brings together 4,000 children from Caen's schools.

Each year, these thousands of children work for an association through their participation. In 2023, the children will participate for the benefit of the association Les Fées Papillons which works at the regional level for sick children. It supports children weakened by the disease and their families but also raises awareness of bone marrow donation, blood donation and platelet donation. The association also collaborates with the onco-hematology department of the CHU of Caen and the pediatric departments of peripheral hospitals.
