The objective of this article is to understand how the specific interactions between actors involved in the production of performance influence the socialization process by which cyclists learn their job. In particular, we try to understand how these interactions determine the reported attitudes towards doping products and methods. We focused on the interactions within the work group to understand how young cyclists learn their job. While analysing this organization of work, our goal is to understand how it influences the perception of the use of performance-enhancing drugs (PEDs). We compared socialization of young elite and U23 cyclists in Belgium, France and Switzerland. We analysed the economic, legal and organizational conditions in each country, And we conducted 70 semi-structured interviews with cyclists and their staff.
