Marathon is a well-known sports event. At first, it was set up to commemorate the soldiers who died because of the news of the victory of the Greek-Persian war. Gradually, it is loved by more and more people because of its unique competitive sports spirit, and more and more people participate in the marathon. It stands to reason that all major cities should report, but in fact marathons are more favored by second-and third-tier cities.

Marathon is so favored by second-and third-tier cities because of its economic benefits. First of all. Although the development of second-and third-tier cities is not as good as that of first-tier cities, they meet the requirements of marathon venues, so they have the basis for holding marathons.

Marathon is a big race, and hundreds of people take part in it every time. These athletes' food, clothing, housing and transportation are the direct consumption to promote urban economic development, and they may be accompanied by relatives and friends when they participate in the competition. By the way, it has injected a lot of impetus into the economic development of second-and third-tier cities. Moreover, holding a marathon will definitely attract a lot of publicity, and the contestants will definitely send a circle of friends to bask in it, and make a lot of publicity for second-and third-tier cities to let more people know about this place.

And after the marathon, many tourists will choose to travel and feel the atmosphere of the marathon. These driving effects will undoubtedly make second-and third-tier cities extremely excited, while first-tier cities are already very developed. Holding a marathon is not conducive to the operation of the city because of traffic delays and other factors, and the benefits brought by marathon are not many for first-tier cities, so first-tier cities rarely hold marathons.
