  More specifically, a location information providing application is installed in the browsing communication terminal 40, and the competition of each competitor 1 is based on the passing time information from the cloud server 30 transmitted to the browsing communication terminal 40. The position information in the course 2 can be confirmed on the displayed map.

  According to the real-time position information providing system 100 of the present invention as described above, it is possible to provide the position information of the player 1 without using a so-called GPS positioning system or the like. It is possible to provide the position information of the player 1 to the spectator 41 without fail.

  As described above, in the present embodiment, it is possible to display the position information of the athlete 1 by the activation of the dedicated position information providing application installed on the smartphone that is the browsing communication terminal 40. In addition, as a modification, it is possible to receive location information and the like by browser connection in a personal computer or a smartphone.

  Moreover, the browsing communication terminal 40 of the present embodiment has a specific player registration function that allows the spectator 41 to register a specific player 1 in the above-described position information providing application. It is possible to register the player 1 in advance and display and provide position information on the map, intermediate time, ranking, number of laps, pace information, etc. of only the support target player 1.

  As a modified example, it is possible to provide a list of location information, intermediate time, rank, number of laps, pace information, etc. of all the competitors 1 and provide the viewing communication terminal 40 especially for those involved in the tournament. It is very effective in understanding the progress of the entire competition. Furthermore, it is possible to display necessary information appropriately on the browsing communication terminal 40 according to the type of competition, and display only a specific competitor 1 with a bib number, number of laps, competition item, etc. on the map. It is also possible to do.

  In addition, when the player 1 registered in advance by the spectator 41 with the browsing communication terminal 40 approaches the spectator 41, the registered communication player approach information is output to the browsing communication terminal 40 (by sound or display). Is also possible. According to such a configuration, it is possible to support without missing the registered competitor 1 even in a competition where there are many players who are difficult to find.
