Attracting participants to events such as marathon leads to expectations of increased socio-economic benefits within the host region. Furthermore, the classification of runners is important for continued running of such events, while participants’ sense of attachment to these events is also critical to repeat participation. The spotlight of this research was on the classification of three types of self-assessment type runners who focus on the concept of running involvement-related recreation specialization, while our aim was to show a correlation between runners’ self-assessments and sense of attachment to these events. The response rate was 247 runners. The relationship between self-assessment types and the event attachment to such events—addiction to events and sense of identity through events—showed a difference between the two senses of event attachment among type 3 of runners (casual, active and committed). Further examination revealed that committed runners showed higher averages of both factors, compared to other groups.
