The King of the Mountains is the title given to the best climber in a cycling road race. Points are awarded to the rider who is first to reach the top of each significant climb. Points are also awarded for riders who closely follow the leader up in each climb. The number of points awarded varies according to the hill classification, which is determined by the steepness and length of the course. The climbers' jersey is worn by the rider who, at the start of each stage, has the highest number of climbing points. At the end of the race, the rider holding the most climbing points wins the classification.
