ABSTRACT
The half marathon approximately 21 kilometers started in the 1980s, and the marathon has shown a diversified development since then. The focus of this research is on the marathon in Taiwan before the COVID-19 pandemic. The selected research method is to integrate the attribute data and spatial data on the GIS platform. Preliminary information on the GIS platform shows that all types of events are held in the western part of the eastern part. The full marathon type shows that the northern metropolitan area and the central metropolitan area are the main event venues in the spatial distribution analysis. Subsequent research data shows that the spatial distribution of the city where the semi marathon is that almost all administrative regions have races. The distribution of half-marathon events is relatively balanced and almost every region has such sport events. © 2021 IEEE.
