The Tour de France was created in 1903 in an attempt to sell more news papers between two rival sports newspapers. Around 60- 80 entrants (not all professional cyclist) began the race and only 24 finished the fourth stage.
Since 1919, the race leader following each stage has been awarded the yellow jersey. Only after the final stage, the wearer of the yellow jersey is considered the winner of the yellow jersey, and thereby the winner of the Tour de France.
Since 1903, the tour has gown from only 5 stages to an amazing 21 stage / 23 day tour around France. The only time that the race was not held was during the two World Wars. Rather than the early entry of anyone with a bicycle who would like to participate, the Tour de France consists of 20-22 teams with 8 professionals in each team.
This year the Tour de France will start in Brussels in honor of the 50th anniversary of the first Tour de France win of Eddy Merckx. You can watch the 106th Tour de France from July 6, 2019 - July 28, 2019.
