4. Don’t Drink and Ride
While France is known for its fine wines, tour rules prohibit the consumption of alcohol during the race. This might sound like a standard practice for athletes competing in a sporting event but until the 1960s, riders in the Tour de France were allowed to throw a few back while cycling to help ease the pain of their ride. However, race runners felt that alcohol was a stimulant for athletes and banned its usage during the tour.
