1. A method for providing a topographical graph, the method comprising:

  • accessing, over a communication network, a database storing road map data associated with a geographic area;

    accessing, over the communication network, a database storing elevation data associated with the geographic area;

    executing instructions via a processor of a user computing device, wherein execution of the instructions by the processor;

    references the elevation data to identify one or more points at which there is a change in incline along roads in the geographic area,constructs the topographical graph, the identified points defining nodes in the topographical graph, and arcs between the nodes representing road segments having a constant degree of incline, wherein nodes and arcs of the topographical graph respectively correspond with geographical positions of the identified points at which there is a change in incline and the road segments having a constant degree of incline, andidentifies a level of perceived exertion for each arc in the constructed topographical graph, wherein the identified level of perceived exertion is based on a user skill level for a mode of travel, the user skill level for the mode of travel having been inputted by the user; and

    providing a selected travel route to the user via a graphical user interface, wherein the selected travel route is selected from a plurality of different possible travel routes between a starting point and an ending point based on a total level of perceived exertion for a set of one or more arcs associated with each travel route.
