problem: I have some "standard routes", that I run / bike regularly. Being able to compare all the performances on one route would be nice.
possible solution: Possibility to create a "list of routes", where each of the standard routes can be characterized by a (short) name, a (longer) description with comments and by its length (i.e. the distance travelled). Then, a new field could be added to the exercise dialog, where one can select one of these standard routes and doing so automatically fills in all the given values (e.g. the distance) of the selected route. Furthermore, one could add a new filter that selects only exercises with a certain route to enable the user to compare performances on a given route.
