This paper deals with the question of whether nature sports are to be counted among the (traditional) sports and Kevin Krein’s recent argument, based on sporting excellence, as to why they should. Krein argues that sports as such are ultimately about sporting excellence and because both so-called traditional sports and nature sports fulfil that criterion, nature sports belong in the sport domain. Here, I show that Krein’s argument rests on an equivocation between two concepts of sporting excellence. Sporting excellence in (...) traditional sports is connected to sporting success. Here agon (contest or competition) dictates or frames areté (striving for excellence). This is not the case for sporting excellence in nature sports, as these are not competitions. We are dealing with two different concepts of sporting excellence and Krein’s argument, based on sporting excellence, must be rejected. It gives no basis for including nature sports in the sport domain. (shrink)
