Information on the location
The Tour de France is an annual multi-stage bicycle race primarily held in France, but whose route varies from year to year and may pass through neighboring countries. The race was first organized in 1903 to promote the sports paper L'Auto (now L'Équipe) and is currently run by the Amaury Sport Organisation. It has been held annually since its first edition except for when it was stopped for the two World Wars.
Appearance in the rap battle
This is the location where Lance Armstrong rapped. The exact location of this segment of the Tour de France appears to be the passage through the Pyrenees. During the battle, duplicates of Lance Armstrong wearing cycling gear can be seen riding through the Tour de France.
