[Purpose] This study aimed to investigate the structural relationships among event quality, spectators‘ destination image, country image, and behavioral intention in the international cycle competition, Tour de Korea 2017. [Methods] The questionnaire was structured in four dimensions: event quality (three sub-dimensions and twelve items), destination image (three items), country image (three items), and behavioral intention (four items). A total of 292 spectators from six hosting cities (Yeosu, Gunsan, Muju, Yeongju, Cheongju, and Seoul) during the event participated in this study. Factor analysis, reliability, validity, correlation analysis, and structural equation modeling analysis were conducted utilizing SPSS 21.0 and AMOS 21.0. [Results] This study indicated that event quality in an international sporting event was found to be the significant factor of spectators’ destination image and country image, which, in turn, significantly influenced the spectators’ intention to revisit to the place of the event and/or the event itself. [Conclusions] The findings of the present study contribute to theoretical understandings of event quality that predicts spectators’ behavioral intention and destination image in a global sporting event. Practically, this study also provides some important suggestions for practitioners who plan marketing strategies for international sporting events.
