For twenty years, typical outdoor lifestyle sports like rafting, snowboarding and rock climbing, which used to be exclusively practised in natural environments, are being offered in controlled artificial settings. This process can be described as 'the indoorisation of outdoor sports'. With this development, questions of authenticity arise. Are these new, commercial forms still authentic lifestyle sports? And can we consider the participants in these indoorised lifestyle sports as authentic? There has been a discussion about authenticity in lifestyle sports since its worldwide popularisation and it is worth to reconsider this discussion against the background of new, commercial versions of lifestyle sports. Therefore, in this paper a qualitative analysis is offered about the consumption of a constructed authenticity in a cultural context increasingly characterized by artificialization.
