The Trail des Ecoliers is a trail-running event held in Champdieu, organized by the Sou des ecoles de Champdieu. The event features three children's races in the afternoon and three adult races in the evening, serving as both a local school-community gathering and a competitive race night.
The series marks its 10th edition and attracts a strong field for its scale, with over 600 participants and entries closing a month in advance. The courses are noted as challenging, with updated routes, indicating it is more than a casual village run.
