The prestigious long-form bike race is won by the cyclist finishing the distance in the shortest accumulated time(overall).
The different coloured jerseys are worn by cyclists who achieve certain special distinctions like best accumulated time in the mountain area(Polka Dot jersey) or the best accumulated time in flat terrains(Green jersey).
The first race, held in 1903 was won by French national Maurice Garin.
The pandemic postponed the race in 2020 by about two months.
