The purpose of this study is to investigate the effect of service value and satisfaction on selection attributes of participants in South Korean marathon races. For the research subjects, those who participated in the marathon races held in South Korea in 2019 were set as the population, and convenience sampling was used. Among them, 350 subjects who participated in the 2019 Gyeongju International Marathon and the 2019 Gongju Baekje Marathon hosted by Newspaper D were selected for sampling. The researcher distributed a questionnaire with three research assistants who had been trained beforehand and collected the survey sheets based on a self-administration method. After excluding 21 sheets, which had been poorly or partially answered, a total of 329 answer sheets (94%) were used as valid samples. The data was analyzed using SPSS WIN 21.0 program through frequency analysis, exploratory factor analysis, reliability analysis, correlation analysis, and multiple regression analysis. The results obtained through such analyses are as follows: First, as a result of verifying the effects of the selection attributes of the marathon participants on the service value, it was found that the sub-factors of the service value including emotional, functional, and social value had positive effects. Second, the selection attributes of the marathon runners had positive effects on satisfaction. Third, the service value of the marathon participants was found to have positive effects on satisfaction.
