The development of a marathon involves the participation of many sponsors，and the analysis and comparison between enterprises is also an important topic affecting the healthy development of the sponsorship market. This paper selects nine large-scale international marathon events carried out in 2020，among which the “double gold” event reaches eight，and analyzes the sponsors involved one by one. A total of 134 relevant enterprises have participated in 170 sponsorship times. The survey found that the sponsor market of marathon events in China is relatively active，and more and more enterprises are willing to participate in the sponsorship team of marathon events. Among them，beverage industries show a higher level from the sponsorship times and sponsorship contributions. In the long run，the sponsorship value of Chinese marathon still needs to be further developed to obtain higher social value.
