Cycling the Alps has created a number of Google Maps and Google Earth tours for each stage of the Tour de France.
Each stage comes with four options:
1. You can view an animated tour of the stage in 3d with the Google Earth browser plug-in.
2. You can view an animated tour with Google Maps Street View (created with the TripGeo application).
3. You can view a Google Map of the route with an interactive elevation chart.
4. You can play a Google Earth browser plug-in game that lets you pretend you are a cyclist in the race. In the game you have to use the arrow keys to follow the route of the stage in 3d.
The embed codes for each of the maps is provided by Cycling the Alps. So if you want to showcase a stage of the Tour de France on your own website you can just cut and paste the code.
