Run recording device, run recording system, and run recording method

A run recording system, comprising:

• a run recording terminal, comprising:
• a processor configured to function as:
• a position acquirer that acquires position information of a runner running at a starting time of running a running event;
• and
• an environment acquirer that periodically acquires during the running event environment information indicating running environment of the runner, the environment information including at least one of an altitude at which the runner is running the running event, a surface condition of a surface on which the runner is running the running event, and an inclination of the surface on which the runner is running the running event;
• and
• a run recording server comprising:
• an adjustment unit that adjusts a running time of the runner running the running event based on the environment information to correct a difference in running load due to running environment differences that may occur between the runner and another runner running in the running event;
• and
• a comparison unit that:
• classifies a first running load of a first runner based on first running environment information indicating a first running environment of the first runner and a second running load of a second user based on second environment information indicating a second running environment of the second runner,
• ranks the first runner and the second runner based on a first running time of the first runner and a second running time of the second runner that are not adjusted by the adjustment unit in response to classifying the first running load and the second running load into a same classification category having a degree of running load, and
• ranks the first runner and the second runner based on the first running time and the second running time that are adjusted by the adjustment unit in response to classifying the first running load and the second running load into different classification categories having different degrees of running load.

A run recording server, comprising:

• a processor configured to function as:
• a position acquirer that acquires, from a run recording terminal of a runner, position information of the runner running at a starting time of running a running event;
• an environment acquirer that periodically acquires during the running event, from the run recording terminal, environment information indicating a running environment of the runner, the environment information including at least one of an altitude at which the runner is running the running event, a surface condition of a surface on which the runner is running the running event, and an inclination of the surface on which the runner is running the running event;
• an adjustment unit that adjusts a running time of the runner running the running event based on the environment information to correct a difference in running load due to running environment differences between the runner and another runner running in the running event;
• and
• a comparison unit that:
• classifies a first running load of a first runner based on first running environment information indicating a first running environment of the first runner and a second running load of a second user based on second environment information indicating a second running environment of the second runner,
• ranks the first runner and the second runner based on a first running time of the first runner and a second running time of the second runner that are not adjusted by the adjustment unit in response to classifying the first running load and the second running load into a same classification category having a degree of running load, and
• ranks the first runner and the second runner based on the first running time and the second running time that are adjusted by the adjustment unit in response to classifying the first running load and the second running load into different classification categories having different degrees of running load.

A run recording method of a run recording server, the run recording method comprising:

• acquiring, from a first run recording terminal of a first runner, first position information of the first runner running at a starting time of running a running event and second position information of a second runner running at the starting time of running the running event;
• periodically acquiring during the running event, from the first run recording terminal, first environment information indicating a first running environment of the first runner and second environment information indicating a second running environment of the second runner, the first environment information and the second environment information including at least one of an altitude at which a runner is running the running event, a surface condition of a surface on which the runner is running the running event, and an inclination of the surface on which the runner is running the running event;
• adjusting a first running time of the first runner running the running event based on the first environment information and a second running time of the second runner running the running event based on the second environment information to correct a difference in running load due to running environment differences between the first runner and the second runner running in the running event;
• classifying a first running load of the first runner based on the first environment information and a second running load of the second runner based on the second environment information;
• ranking the first runner and the second runner based on the first running time and the second running time that are not adjusted in response to classifying the first running load and the second running load into a same classification category having a degree of running load;
• and
• ranking the first runner and the second runner based on the first running time and the second running time that are adjusted in response to classifying the first running load and the second running load into different classification categories having different degrees of running load.
