What is Keirin?
Keirin is a track cycling event that involves a group of cyclists racing over a distance of 2,000 meters. The race begins with a motorized pacer, known as a “derny,” which leads the cyclists for the first laps before pulling off the track, allowing the riders to sprint for the finish. The event is characterized by its tactical nature, as riders must position themselves strategically to gain an advantage over their competitors.
History of Keirin
Keirin originated in Japan in 1948 as a form of gambling and has since evolved into a professional sport.
. The name “Keirin” comes from the Japanese words “kei” (meaning “to race”) and “rin” (meaning “wheel”). The sport quickly gained popularity, leading to the establishment of the Japan Keirin Association in 1950, which regulates the sport and oversees its events.
Today, Keirin is not only a popular betting sport in Japan but also an Olympic event, having been included in the Olympic Games since 2000. The event has expanded internationally, with competitions held in various countries, showcasing the talents of elite cyclists from around the world.
