摘要:Evidence from several studies shows that small-scale sport events may have more positive repercussions for the host community than major ones in terms of both economic and social impacts. This study estimates the economic impacts on a small community derived from athletes’ expenditure at a specific small-scale sport tourism event, the Italo-Swiss mountain endurance trail CollonTrek. Even if this kind of event is considered a minor sport event, generating very limited economic activity, this study supports the hypothesis that the funds invested by the public administration are compensated for by revenue generated during the trail. In fact, according to the three analyzed scenarios (Conservative, Average and Liberal), for each euro invested by the public administration, an economic return between €17.62 and €18.92 has been estimated, and between €5.64 and €6.9 (32%–36.47%) represent the direct economic return for the local community. Furthermore, in addition to the direct economic benefits, in accordance with the feedback from a sample of participants at the event ( n = 180), this kind of event has positive implications in terms of future tourism for the host valley, pointing out how this kind of tourist activities has positive repercussions in terms of economic and social sustainability.
