The survey found that China’s marathon sponsorship market still has great market potential that is worth exploring and tapping. There are more and more companies willing to market through marathon events，but the actual benefits that companies can get from marathon events still need scientific evaluation. The marathon also attracted companies that are weakly related to the event，such as car companies，real estate companies，electrical appliances companies，jewelry companies，and banks. Based on the statistics of the sponsor brands of the “double-gold” marathon，the research team found that the 8 marathon events were supported by 121 sponsor companies，involving more than 50 market segments. Event sponsors mainly include mineral water or beverage companies，automobile companies，sports equipment companies，sports shoes and clothing companies，beer companies，insurance companies，banks，real estate companies，and others（including food，catering，communications companies，etc.）. The survey showed that the top three companies with the highest recognition of sponsors are mineral water or beverage companies，sports equipment companies and automobile companies.
