Researching more into polka dot patterns, and the history and culture of polka dots in France, I knew that one of the most visually significant use of polka dots is within the Tour de France annual bicycle race. Throughout the course, four coloured/patterned jerseys are distributed to racers for particular achievements and accolades.
The polka dot jersey, maillot à pois rouges, represents the 'King of the Mountains'. Points are awarded to the first rider to reach the crest of designated hills and mountains, all of which being individually graded according to steepness, length, position on the course, and points correspond to these grades. Despite the best climber award starting in 1933, the jersey was not worn until 1975.
