There are not many researches and references related to service quality and satisfaction of a marathon event. This research was aimed at the comparison and discussion of the relationship between service quality and satisfaction from participants' aspect in five marathon events held in Taiwan in 2005. According to the theory and factor analysis, the factors of service quality of a marathon event were "interaction", "environment and facility", "provide needs", and "race information"; the factors of satisfaction were "route", "expectation met", "promotion", and "service staff". The t-test indicated that female participants were more agreeable with service quality of the host offer in "interaction", "race information", "expectation met" and "promotion" than male. ANOVA analysis showed that age and occupation had significant differences in factors of service quality and satisfaction. Furthermore, significant differences were made in different marathon events, meaning different standard of service quality and satisfaction was offered in every marathon event, meaning a different correlation analysis reflected that "interaction quality" in service quality had the relationship with "promotion", "route", and "expectation met" in satisfaction, implying that service quality had close relationship with satisfaction. It is recommended that the marathon association in R.O.C. or affiliated organizations can define the standards of procedure for services provided in a marathon event as a prototype for the host organization's reference while holding and implementing a marathon event. Through using all the standardized procedures, the level of service quality can be elevated and satisfaction can be attained as requested accordingly.
