Non-traditional sport event has received much attention in recent years. The purpose of this study was to investigate the role of sport event image and attitudes toward event in predicting satisfaction with event and behavioral intentions. A sample of 182 obstacle course runners in Spain was surveyed to test the research model using structural equation modeling. The results showed that event characteristics, which is one of the dimensions of sport event image, and participants' attitudes toward event positively influenced satisfaction, which in turn, together with attitudes, positively influenced behavioral intentions for repeat visits and recommendations. However, the destination characteristics dimension of sport event image had no impact on attitudes and satisfaction. Finally, satisfaction had a mediating effect on the relationships between event characteristics and behavioral intentions, and attitudes and behavioral intentions. The theoretical and practical implications of these results are discussed.
