Since the marathon is considered a large-scale sports event, there are generally a large number of people participating in this event. In this large-scale event, with a large scope of activities and a large number of participants, how to control it is worthy of reflection and discussion. The key to control is to truly understand the situation of each player during the game. With the features and functions of RFID wristbands, it is very suitable for large-scale sports events such as marathons. Because it is necessary to control each competitor, it is the best choice for players to wear RFID wristbands. It can not only improve mastery, but also improve the competition fairness and security.

Therefore, adding a positioning device to the RFID wristband can effectively track the movements of the players, so as to check whether the players are running according to the route specified in the competition. In this way, various artificial cheating can be effectively prevented, thereby improving the fairness of the competition. On the other hand, designed reading devices will be set up along the race route. For example, after a runner completes a certain distance, the device will automatically read the RFID wristband. Through this method, the runner’s movements can also be tracked. At the same time, It can record the time of arrival here, so wearing an RFID wristband can significantly improve the player's mastery and the safety of the races.
