**2. Aim of the Study**

The main purpose of this study is to investigate the impact of non-mega sporting events on the perception of negative externalities of host residents. The detailed aim of the study was to examine whether the inhabitants of the city feel the negative effects of organizing sporting events (communication problems or inappropriate behavior of supporters) and do they believe that these events increase the level of crime in the city or, despite these inconveniences, they are satisfied with the organization of sporting events in their place of residence. Two, different ranks of sporting events organized in Poznan (one of the largest Polish cities and the most important sports centers in Poland) were selected for the empirical research. The first one is the Poznan Half Marathon—medium scale mass event, the second one is Cavaliada—elite international equestrian event.
