Wall Street Journal -Tour de France Map
The Wall Street Journal are using Google Maps to show the route of the stages of the Tour de France. The map is particularly impressive at the moment as the race enters the mountain stages.
The WSJ's map includes an interactive elevation chart. This means the user can click on the steepest climb in the stage or the steepest downhill sections and find out exactly where they are on the map.
The WSJ map also includes a nice map animation when you click on each stage of the race. On the initial load of each stage the map animates the stage's route, whilst also highlighting the elevation at each point of the stage.
