Abstract: An electronic device for tracking a distance traveled by a user along a course comprises a location determining element, a memory element, and a processing element. The location determining element is configured to receive location signals from a satellite-based positioning system and to determine a current geolocation of the user. The memory element is configured to store geolocations for a start point, an end point, and a plurality of intermediate event points that are passed by the user as he travels along the course, wherein each event point is positioned at a known distance from a stored geolocation such as the start point or another event point. The processing element is configured to determine a measured distance based on the current geolocation of the user and to determine a calibrated distance as a function of the measured distance and the known distances of the event points.
