A method of creating a customizable exercise route for a user of a personal navigation device is disclosed. The method includes providing routing instructions for a user along a first route, recording a first speed for a user traveling between a first point and a second point on the first route, providing routing instructions for a user along a second route, recording a second speed for a user traveling between a third point and a fourth point on the second route, comparing the first speed and the second speed to calculate a performance difference related to the first route and the second route, and notifying the user about the performance difference.
