As a long-established event, the marathon has a unique charm and is highly attractive to people. A marathon race, with a large number of participants, needs to accurately record the ranking and results of each athlete, which is very difficult and often faces the following problems: 1.If several runners pass the timing point quickly and almost simultaneously, how to record each person’s time? 2.How to accurately locate each runner’s path? 3. How will the results be recorded when the runners reach the finish line and ensure that they will not be missed? 4. How to prevent cheating? Using RFID tags can effectively solve the above problems. Intelligent management of RFID marathon race can do active recognition, active timing and active sorting of the final result. Concentrated management on the same system to avoid the possibility of manual errors, and can also accurately locate the athlete's running path to prevent any abnormalities. Complete the one -to -one correspondence between RFID electronic labels to the athletes, and ensure that the results are true and credible. At present, the main UHF RFID tags commonly used by organizers are mainly the following: RFID badges, RFID wristbands, and shoes with RFID tags. RFID readers are placed at the starting line, finish line, etc. When athletes wearing the shoes with RFID electronic tags and pass the RFID reader, the reader will read the ID of the RFID electronic tag on athlete's shoes and record the moment.  Meanwhile, the software system will process and display the information. The whole recording process can be completed in just a few milliseconds. In this way, the organizer can accurately and reliably record the starting and finishing moments of each athlete, which also guarantees the fairness of the competition and accurate athlete results. The timing advantages of RFID technology in marathon races are: 1.No staff intervention, automatic collection of statistics, accurate timing to ensure fairness. 2.RFID tags have become popular, inexpensive, reusable, each tag ID is unique and storage information capacity is large.
