As a sports event with rapid development in China，urban marathon has taken root in many cities. Taiyuan International Marathon was born in 2010，and has successfully held 11 times so far，and has been successfully selected as “double gold club”. Under the influence of the special year 2020，TAIMA still actively runs the competition，and finally gets great praise. All these success cannot be separated from the close cooperation between the event organizations. Based on the analysis of the sponsorship，media and technology of TAIMA，this paper summarizes the importance of government led and professional competition companies，and discusses the sponsorship，promotion and technology related to the competition companies. It is proposed that marathon is not only a pure competition，but also a great platform for showing economy，politics，culture and history；The operation company should coordinate the relationship between departments；We will continue to develop our support，promotion and technology，and improve the business level of TAIMA.
