Understanding the development trend of the marathon sponsorship market is conducive to the healthy operation of marathon events and the effective development of the sponsorship market. By calculating the scores of the three first-level indicators of sponsorship market conditions，event value，and sponsorship effects，this article draws the scores and rankings of the eight major marathon sponsorship markets.
