Race With Maps allows a runner to use a race course designed in Google MyMaps. During the run, as the runner encounters the MyMaps Placemarks of the custom course, RWM makes audio announcements using the description of the Placemark. Arriving at Markers, crossing Lines, going over an Area boundary all cause RWM to fire the audio announcement placed in the description of the Placemark. And RWM can insert race time, race distance, pace and deviation from a time goal into the announcement. A Start Line Placemark automatically starts the race while a Finish Line Placemark stops the race. This allows a runner to author a race course in MyMaps with race progress updates, directions, points of interest, fueling/hydration reminders and more. And since RWM uses .kml files, these Projects can be shared with others.
