He proposed that the leader with the fastest timing after each stage would wear the yellow jersey and the overall fastest would get the jersey at the end of the race. The yellow represented the color of the newspaper, L’Auto-Velo.2021 Tour de France: When and where to watch, TV and LIVE streaming detailsOn 18 July, 1919, around two o’clock in the early morning, Desgrange handed over the yellow jersey to the then leader of the stage, Eugène Christophe, making him the first rider to wear the jersey. However, unlike today, the jersey was made of wool and Christophe complained that it made him look silly. He insisted that it made him look like a canary.2021 Tour de France: Team Jumbo-Visma full squad, top riders, predictionsThe jersey is still in use and is handed to the overall race leader in the general classification. But after the death of Desgrange in 1940, his initials, HD, was added to the jersey near the waistline. Only four cyclists so far have won the yellow jersey five times: Jacques Anquetil and Bernard Hinault of France, Eddy Merckx of Belgium and Miguel Indurain of Spain.In 2020 Tour de France, UAE Team Emirates’ rider, Tadej Pogačar of Slovenia, won the yellow jersey.
