The Cotonou Nocturne is a nighttime walk that aims to raise awareness about environmental protection while bringing together different social groups through sport. Unlike morning eco-running activities where participants collect plastic waste, the Cotonou Nocturne is characterized by a walk animated by slogans and educational signs. Its goal is to remind everyone that urban cleanliness is a collective responsibility and essential to public health. This inclusive event will allow everyone, depending on their abilities, to cover between two and eight kilometers, with stops planned for less endurance participants. By partnering with this event, the BIIC encourages community animation, offers a showcase for local talent, and creates convivial moments that strengthen social ties by highlighting sporting and cultural activities.
