The anti-doping policy is based on three institutional pillars of varying importance and officially relies on two major motives:
the defense of sports ethics and the protection of athletes’ health. However, behind these official grounds, other considerations –i.e. moral, political and financial concerns –appear to shape anti-doping policy. Furthermore, the current trend of anti-doping efforts is to develop activities that tackle the supply-side of the doping market. In this article, we consider the possible impact of the emphasis on supply-side anti-doping on sport. The project focuses on Belgian and French elite cycling and relies on a multi-method instrumentation set, including the realisation of 77 semi-structured interviews among policy-makers, cyclists and their medical and technical staff as well as the administration of an online survey among competitive cyclists.
