A required time calculating system including a required time calculating section, in which the required time calculating section extracts the topographic data of one section of a measured route similar to or matching the topographic data of one section of a calculated route determined from the positional and altitude information of each point in the above-described section of the calculated route divided into a plurality of sections from among the topographic data of the measured route determined from the positional and altitude information of each point of the measured route detected by a first sensor that travels with a human when the human travels a predetermined section of the measured route, and calculates the amount of time required for the human to travel the above-described section of the calculated route based on the amount of time taken for the human to travel the above-described section of the measured route.
