Summary of the Invention

Problems to be Solved by the Invention

[0007] As described above, in conventional marathons, there are problems such as a large amount of waste paper cups or plastic cups being generated, and a large amount of used empty PET bottles being generated. Although efforts have been made to reduce waste and the like, there are not enough measures to smoothly operate the marathon without hindering the competition of the marathon.

[0008] In addition, depending on the marathon, there are attempts to eliminate paper cups or plastic cups, reduce the number of PET bottles, and have runners carry their own cups and bottles and pour the water provided at the water supply points into their own cups or bottles and drink.

[0009] However, the above attempts take time for the runners' operations at the water supply points. If the number of water supply points is small, the runners will be stuck at the water supply points. On the contrary, if the number of water supply points is large, it will take time for the organizers to install and remove them, and it is difficult to smoothly operate the marathon without the runners being stuck.

[0010] In addition, Patent Document 1 is for runners to search for running routes for practice and is not used by the organizers of marathons.

[0011] The present invention has been made in view of the above actual situation, and an object thereof is to provide a water supply system that can smoothly operate the marathon without runners getting stuck on the marathon course by reducing the number of PET bottles without using paper cups or plastic cups.

Means for Solving the Problems

[0012] The present invention for solving the problems of the above prior art is a water supply system in a marathon race, wherein a plurality of water supply stations are provided on the marathon course, the interval between the water supply stations is 150 m or more and 400 m or less, and at the water supply stations, a bottle for providing water from a first water injection port and a jug container for providing a sports drink from a second water injection port are installed. For each runner participating in the marathon race, the total amount of water and sports drink is 1.5 liters or more and 2.5 liters or less, and the number of water injection ports per runner participating in the marathon race is 0.17 or more and 0.19 or less in total for the first water injection port and the second water injection port. A water supply system characterized by the above.

[0013] The present invention is characterized in that, in the above water supply system, the interval between the water supply stations is 180 m or more and 300 m or less.

[0014] The present invention is characterized in that, in the above water supply system, two second water injection ports are provided in the jug container.

[0015] The present invention is characterized in that, in the above water supply system, in the second half of the marathon course, the concentration of the sports drink in the jug container is gradually increased step by step.

[0016] The present invention is characterized in that, in the above water supply system, no water supply station is provided from the start of the marathon course to a distance of 10% of the course.

[0017] The present invention is characterized in that, in the above water supply system, a chlorine meter is installed in the jug, and data on the chlorine concentration is output to the outside.

[0018] The present invention is characterized in that, in the above water supply system, based on the staying situation at the water supply point from the running data of the runner obtained by the watch worn by the runner, the state of the water supply point in the next marathon race can be adjusted.

[0019] In the above water supply system, the present invention is characterized in that it obtains the oxygen uptake amount of a runner from running data, calculates the predicted finish time of the runner from the oxygen uptake amount, and calculates the running efficiency of the runner by comparing it with the actual finish time of the runner.

[0020] In the above water supply system, the present invention is characterized in that it obtains data on the water supply situation from the questionnaire response data of the runner and can provide advice on the water supply situation based on the running efficiency of the runner.

[0021] In the above water supply system, the present invention is characterized in that it can evaluate the operation status of a marathon event by aggregating the running efficiency calculated based on the running data provided by the runners who participated in the marathon event.

Effect of the Invention

[0022] According to the present invention, a plurality of water supply stations are provided on the marathon course, the interval between the water supply stations is 150 m or more and 400 m or less, and at the water supply stations, a bottle for providing water from a first water injection port and a jug container for providing a sports drink from a second water injection port are installed. For each runner participating in the marathon event, the total amount of water and sports drink is 1.5 liters or more and 2.5 liters or less, and the number of water injection ports per runner participating in the marathon event is 0.17 or more and 0.19 or less in total for the first water injection port and the second water injection port.

Mode for Carrying Out the Invention

[0024] Embodiments of the present invention will be described with reference to the drawings. [Outline of Embodiment] The water supply system (this system) according to the embodiment of the present invention provides a plurality of water supply stations on the marathon course, the interval between the water supply stations is 150 m or more and 400 m or less, and a bottle for providing water from a first water injection port and a jug container for providing a sports drink from a second water injection port are installed at the water supply station. The total amount of water and sports drink for each participant is 1.5 liters or more and 2.5 liters or less, and the total number of the first water injection port and the second water injection port for each participant is 0.17 or more and 0.19 or less. By shortening the interval between the water supply stations compared to the conventional interval and increasing the number of water injection ports of the bottle and the jug container compared to the conventional ones, runners can pass through the marathon course without stagnation, and by not shortening the interval between the water supply stations too much, the work of installing and removing the water supply stations can be suppressed, and the operation of the event can be smoothly carried out.

[0025] Here, in this system, it is premised that runners participate with a bottle (my bottle) of 200 milliliters or more, and the carrying of a cup (my cup) in addition to the my bottle is also encouraged. As the my bottle, a bottle with a capacity of 200 milliliters or more and 500 milliliters or less is appropriate for runners, and in particular, a capacity of about 400 milliliters is considered optimal.

[0026] [This System: Figure 1] This system will be described with reference to Figure 1. Figure 1 is a schematic diagram of this system. As shown in Figure 1, in this system, water supply stations 10 are provided at intervals of about 200 m on the marathon course, and a stainless steel container (stainless steel jug / jug) 20 and a returnable bottle (bottle) 30 are arranged at the water supply stations 10.

[0027] The water supply stations 10 are installed at intervals of approximately 200 m because if the installation interval is 500 m or more, runners will concentrate and stagnate at the water supply station, and conversely, if the interval is 100 m or less, the work of installing and removing the water supply stations by the staff will become complicated, and the time for installation and removal will become long.

[0028] Therefore, the installation interval is preferably 150 m or more and 400 m or less, and an interval of 180 m or more and 300 m or less is realistic. In particular, an interval of approximately 200 m is appropriate and is used as a guideline.

[0029] In addition, in the case of a full marathon, since runners rarely take water in the first 4 - 5 km after starting, it is not necessary to provide a water supply station in the first 4 - 5 km. Also, in the case of a half marathon, a 20 km marathon, or a 10 km marathon, it is not necessary to provide a water supply station in the first 1 / 10 (one-tenth) of the entire course.

[0030] [Jug 20: Figure 2] Next, the jug 20 will be described with reference to Figure 2. Figure 2 is a schematic diagram of the jug. As shown in Figure 2, the jug 20 includes a cylindrical main body 21, a lid 22, and faucets 23a, 23b.

[0031] The main body 21 has a bottom surface and a side surface, is cylindrical, has a lid 22 attached to the upper part, and sports drink is poured into it. The jug 20 can accommodate 20 liters of sports drink. The lid 22 is circular and is attached to the main body 21 so as to cover the upper part of the main body 21.

[0032] The faucets 23a, 23b correspond to the "second water injection ports" in the claims, are provided separately on the lower front side of the side surface of the main body 21, and when the standing lever is pushed or pulled down, the sports drink is discharged from the water injection port, and when the lever is released, the lever returns to the standing state and the discharge stops.

[0033] By providing two faucets 23a and 23b separately on the side of the main body 21, two runners can be supplied with water simultaneously from one jug 20. In the full marathon of this embodiment, three jugs 20 can be placed on one table, and six jugs 20 are prepared on two tables at one water supply point. After the event, the jugs 20 are washed and reused.

[0034] [Bottle 30: Figure 3] Next, the bottle 30 will be described with reference to Figure 3. Figure 3 is a schematic diagram of the bottle. As shown in Figure 3, the bottle 30 includes a main body 31 and a water inlet 32, and mineral water (water) is contained therein. The bottle 30 is filled with 12 liters of water.

[0035] The main body 31 includes a bottom surface 31a, a side surface 31b, and an upper surface 31c. The water inlet 32 is attached by removing the cap attached to the center of the upper surface 31c. The bottle 30 is installed such that the water inlet 32 faces obliquely downward. This makes it easier for water to flow out.

[0036] The water inlet 32 corresponds to the "first water inlet" in the claims and has a knob shaped like a laundry clip. When the knob is pinched with a finger, water comes out, and when released, the knob returns to its original position and the water stops flowing.

[0037] In the full marathon of this embodiment, four bottles 30 can be placed on one table, and eight bottles 30 are prepared on two tables at one water supply point. After the event, the bottle 30 is drained of water and reused as a PET bottle.

[0038] [Sports drink concentration of jug 20] In this system, since the sports drink provided by the jug 20 is made by dissolving the powder that is the source of the sports drink in water, the concentration can be adjusted.

[0039] Therefore, the concentration of the sports drink is made higher in the jug 20 installed in the second half of the course than in the jug 20 installed in the first half. As a result, it is possible to provide a concentrated sports drink to runners who accumulate fatigue in the second half of the course, which helps prevent dehydration and recover from fatigue, reduces the number of breakdowns, and enables the smooth operation of the event. In particular, in the second half of the course, it is effective to gradually increase the concentration of the sports drink.

[0040] [Situation of water supply stations] The installation interval of the water supply stations is as described above. The installation situation of the jug 20 and the bottle 30 at the water supply stations will be specifically described. In the case of a marathon event with 19,000 to 20,000 runners participating, the total amount of the sports drink in the jug 20 and the water in the bottle 30 is about 40 tons, and about 2 liters are prepared for each runner. That is, it is desirable to prepare an amount of water or the like of 1.5 liters or more and 2.5 liters or less for each runner.

[0041] A total of about 3,500 are prepared, which is the sum of the number of faucets 23a and 23b of the jug 20 and the number of water injection ports 32 of the bottle 30. Therefore, about 5 to 6 runners will use one water injection port (any one of the faucets 23a, 23b, and the water injection port 32). That is, for each runner in the marathon event, the number of water injection ports is prepared to be 0.17 or more and 0.19 or less, and it is desirable that the number of water injection ports is prepared according to the number of participants so that 5 or 6 runners can use one water injection port.

[0042] Also, the ratio of the arrangement quantity is adjusted so that the quantity of the jug 20 and the bottle 30 installed in the second half of the marathon course is increased compared to the quantity installed in the first half. This is because runners get tired and desire moisture in the second half of the course. Specifically, at the water supply points, in the case of a marathon event with 19,000 to 20,000 runners participating, the amount of water, etc. is adjusted so that at the point with the least amount of water, etc. (about 170 liters), and at the point with the most amount of water, etc. (about 400 liters), the amount of water, etc. is about 2.3 times that at the least point.

[0043] Also, at the food supply points in the water supply points where food such as raisins, chocolate, and cookies is provided, when the runners take the food, since they desire moisture, the amount of water, etc. is made more than that at the points where no food is provided.

[0044] [Application Example: Figure 4] Next, the application example of this system will be described with reference to Figure 4. Figure 4 is a schematic diagram of this management system. As shown in Figure 4, this management system is composed of a headquarters server 41, a network 42, a sensor 51, and a smartphone 52.

[0045] In this management system, a sensor 51 that can measure changes in the amount of water, etc. in the jug 20 and the bottle 30, for example, a weight sensor measures the decrease in the amount of water and transmits it to the headquarters server 41 using IOT (Internet of Things) technology, so as to grasp the situation of each water supply point and perform replenishment promptly.

[0046] Also, a notification that the remaining amounts of the water supply point ID at the water supply point location and the installed jug 20 and bottle 30 are decreasing can be sent from the staff's smartphone 52 to the headquarters server 41, and the headquarters server 41 can grasp the situation of each water supply point and perform replenishment promptly.

[0047] Also, the bottle 30 can be photographed with the staff's smartphone and uploaded to the headquarters server 41, and AI (Artificial Intelligence) analyzes the remaining amount from the photographed image, so as to grasp the situation of the bottle 30 at each water supply point and perform replenishment promptly. These collected data will be used for the operation of future events.

[0048] When this system is applied to a competition with 19,000 to 20,000 runners participating, if it is applied, about 31,500 two-liter plastic bottles, about 500,000 paper cups and plastic cups, and about 26,500 500-milliliter plastic bottles that were distributed after the finish can be abolished, and a large amount of garbage such as the cardboard boxes for packing them can be significantly reduced.

[0049] [Another application example] Another application invention is based on the improvement of this system and the questionnaire of the competition that has already been implemented, and the improvement based on the data (runners' data) of the running watch worn by the runners. In another application example, the point is to provide hygiene, safety, and comfort to the runners.

[0050] [Another application example (1)] Another application example (1) is that in this system, a chlorine meter is installed in the jug 20 that stores the sports drink, and the remaining chlorine concentration is measured to manage the hygiene aspect in the jug 20. In order to make the measured value of the chlorine meter easy to see, a display unit for displaying the measured value may be provided outside the jug 20. Also, the measuring instrument may be connected to a communication device, and the measured value may be managed by the headquarters server 41 via the Internet 42 wirelessly.

[0051] [Another application example (2)] Another application example (2) is to use the data (runners' data) of the running watch with the consent of the runners in the water supply system of the marathon competition, and the obtained runners' data is stored in the headquarters server 41. The wearing of the running watch accounts for more than 70% of the competition participants. The data that can be obtained is the data of a specific period of the runner corresponding to the runner ID such as the runner's bib number. For example, the data for one week including 3 days before running, the day of the marathon competition, and 3 days after running can be considered.

[0052] This runner data includes running state data such as the position, speed, and heart rate of the runner on the course, and determines the presence or absence of water supply in the stopped state at the water supply point from the running data of the runner. Analyze the concentration degree from the running data of the runner to the water supply point, and adjust the arrangement of the water supply points in the competitions after the next time. In addition, for the runners who receive water from the running state data, adjust the ratio of water and sports drinks, the concentration of sports drinks, etc. in the competitions after the next time.

[0053] In addition, as runner data, data on the oxygen uptake of the runner can be obtained. Regarding all the obtained runner data, the relationship between the oxygen uptake corresponding to the runner ID and the actual completion time (actual completion time) of the actual competition can be plotted on a graph to grasp the situation and trends of the runners participating in the competition from the distribution state.

[0054] Furthermore, based on the oxygen uptake, the predicted time of the competition completion time can be calculated from the physical ability of the runner (running ability data of the runner, etc.), and by comparing with the actual completion time, the competition can be evaluated whether the participating runners could demonstrate their abilities.

[0055] Specifically, calculate the predicted time of each runner from the oxygen uptake of the runner data provided corresponding to the runner ID, and calculate the ratio (%) of their respective predicted time and actual completion time ((actual completion time / predicted time) × 100: running efficiency). Thereby, it is possible to know to what extent the runner has demonstrated performance with respect to the predicted time. When the runner can complete the course earlier than the predicted time, the running efficiency becomes smaller than 100%, and when it is later than the predicted time, the running efficiency becomes larger exceeding 100%.

[0056] If the running efficiency of all runners provided with the predicted time on the horizontal axis is plotted and displayed, it is possible to evaluate whether the event was one in which the overall runners were able to perform, that is, whether the event operation can be evaluated, from the state where the running efficiency is drawn above and below the 100% reference line.

[0057] [Another application example (3)] In another application example (3), questionnaire response data is aggregated in association with the runner ID from a smartphone or a personal computer (PC) for the runners who participated in the event. The questionnaire response data is aggregated in association with the runner ID and stored in the headquarters server 41.

[0058] It is possible to improve the water supply system from the questionnaire results (questionnaire response data). In addition, by linking the questionnaire response data and the runners' data by the runner ID, highly accurate analysis can be performed using both the runners' data and the questionnaire response data, and the effect of improvement can be enhanced.

[0059] Specifically, by obtaining the answers to the amount and ratio of sports drink and water intake at the water supply point (usage data) from the questionnaire response data, and referring to the usage data at the water supply point of runners with good running efficiency, advice on the water supply usage method is provided to runners with the same oxygen intake, so that information that reduces failures and improves running efficiency can be provided to the runners participating in the next event.

[0060] Also, sleep data of runners with good running efficiency is extracted and aggregated from the sleep data of the runners before and after the event of the runners' data, and advice on sleep is provided to runners with the same oxygen intake based on the aggregated sleep data, so that information that reduces failures and improves running efficiency can be provided to the runners participating in the next event.

[0061] [Another application example (4)] In another application example (4), the data of the malfunctioning participants is aggregated. The malfunctioning participant data corresponding to the runner ID is aggregated and stored in the head office server 41. Based on the malfunctioning participant data, care can be provided for the locations where the malfunctions occurred according to the symptoms of the malfunctions, improvements can be made at the water supply points, and a safe marathon event can be realized.

[0062] [Effects of the Embodiment] According to this system, a plurality of water supply stations are provided on the marathon course, the interval between the water supply stations is 150 m or more and 400 m or less, a bottle 30 that provides water from the water injection port 32 and a jug 20 that provides sports drinks from the faucets 23a and 23b are installed at the water supply stations, the total amount of water and sports drinks for each participant is 1.5 liters or more and 2.5 liters or less, the total number of the water injection port 32 and the faucets 23a and 23b for each participant is 0.17 or more and 0.19 or less, the interval between the water supply stations is made shorter than the conventional interval, and the water injection ports and the like of the bottle 30 and the jug 20 are increased as compared with the conventional ones. As a result, runners on the marathon course can move forward without stagnation, and by not making the interval between the water supply stations too short, the work of installing and removing the water supply stations can be suppressed, and the operation of the event can be smoothly carried out.

[0063] By reexamining the number and location of the water supply stations in the next event based on the runners' data, questionnaire response data, and malfunctioning participant data from last year, it is possible to realize a marathon event that is safe and comfortable for the runners. For example, water supply points where runners consume a large amount of water in the latter half of the course are dispersed, the ratio of water to sports drinks is optimized, and the concentration of the sports drinks is also adjusted, which can reduce the number of malfunctions. In addition, in areas where a large number of malfunctions occur, measures are taken to encourage water replenishment, which can reduce the number of malfunctions and improve safety.

Industrial Applicability

[0064] The present invention is suitable for a water supply system that can smoothly operate a marathon event without causing runners to stop at the marathon course, by reducing the number of PET bottles without using paper cups or plastic cups.
