The Meaning Behind the Jerseys
Yellow: The overall leader on general classification (GC). GC is the sum of each day’s finish times, less any time bonuses the rider might earn for a stage win or place. The yellow jersey of race leader therefore goes to the rider with the lowest total time for the race.
Polka Dot: The white jersey with red dots is awarded to the race’s best climber, or to be precise, to the winner of a points contest that’s conducted at the top of each of the race’s climbs.
Green: There are points allocated to the position in each day’s finish and the rider with the most number of these points wears the green jersey. This jersey is typically a contest between the sprinters - riders who can accelerate very quickly at the end of a stage to win the final dash across the line.
White: Best young rider. In some sports 25-year-old athletes are making retirement plans, but in cycling, and especially in stage racing, riders don’t develop the necessary stamina to succeed until their mid-to-late 20s.
