Run recording device, run recording system, and run recording method
A position acquirer acquires position information of a runner running with a certain time set to the starting point of a running time. An environment acquirer acquires environment information indicating running environment of the runner. An information storage unit stores acquired position information together with information on the acquisition date and time. An adjustment unit adjusts, based on the environment information, a running time or distance calculated with the position information such as to correct a difference in the running load due to running environment that may occur between the runner and another runner running with the same certain time set to the starting point of a running time. An output unit displays a result of comparison between the adjusted running time or distance and adjusted running time or distance of another runner running with the same certain time set to the starting point of a running time.
