what is the point of the keirin bike race
Keirin Keirin (競輪 / ケイリン, [keːɾiɴ]) – literally "competition ring" – is a form of motor-paced cycle racing in which track cyclists sprint for victory following a speed-controlled start behind a motorized or non-motorized pacer. It was developed in Japan around 1948 for gambling purposes and became an official event at the 2000 Olympics in Sydney, Australia.
General classification in the Tour de France The Tour de France, and other bicycle stage races, are decided by totalling the time each rider takes on the daily stages. Time can be added or subtracted from this total time as bonuses or penalties for winning individual stages or being first to the top of a climb or for infractions of the rules. The rider with the lowest overall time at the end of each stage receives a ceremonial yellow bicycling jersey and the right to start the next stage, usually the next day, of the Tour in the yellow jersey.[11]
