A method of calculating an exercise goal includes receiving a selection of exercise route data from the user indicating a length of an exercise route, calculating a distance that the user has completed on the exercise route and a corresponding elapsed time for a completed portion of the exercise route, and calculating a target pace for a remaining portion of the exercise route not yet completed, the target pace indicating a pace at which the user needs to move along the exercise route in order to achieve an exercise goal associated with the exercise route data received from the user. The method also includes outputting the target pace to the user for informing the user about the target pace, and repeatedly dynamically calculating the target pace and outputting the target pace until completion of the exercise route.
