Path selection of sustainable development of the Olympic Games in the new era is not only the fundamental way to solve the bottleneck of the current sustainable development of the Olympic Games, but also an important guarantee for the healthy and sustainable development of the Olympic Games in the future. This paper combs and analyses the practical bottlenecks of sustainable development of the Olympic Games in the new period by using the research methods of literature, induction and deduction, and summarizes the practical exploration of sustainable development of the Olympic Games in the new period. It is found that the sustainable development of the Olympic Games in the new era is facing the realistic bottlenecks of the decreasing number of bidding countries, the sustained growth of the scale of the events, the gradual increase of restrictive factors, the repeated prohibition of Olympic scandals and the excessive penetration of commercial factors. At present, Taking new measures of marketing, supporting and protecting clean athletes, promoting the sustainable development of host cities and innovating the host election of the Olympic Games are mainly explored in practice for the sustainable development of the Olympic Games. Suggestions: Creating the “Olympic National Brand Plan” to realize the income increase and income generation of the National Olympic Committee; using “multi-city co-operation” and “multi-country co-operation” to minimize the burden of the host country or host city; using the mode of “invitation system” and “application system” to maximize the expansion of main target groups of the host country of the Olympic Games; Optimizing the distribution of rights and interests in the commercial development of the Olympic Games, Enhancing the enthusiasm of the Olympic bid.
