Keirin is an exciting type of bike race.
It started in Japan around 1948. Now, it is a big event in the Olympics.
In a race, riders follow a pacer. A pacer is a person on a motor or a bike. The pacer helps the racers build speed. The riders must stay behind the pacer for three laps.
The pacer leaves the track before the race ends. Then, the riders sprint as fast as they can to win. Some riders can go over 70 km per hour!
In Japan, being a pro rider takes hard work. New riders go to a special school. They must train for 15 hours every day.
Riders have different ranks based on their skill. You can tell their rank by the colors on their shorts. The best riders are in the SS class. They wear red shorts with black stripes and white stars. These top nine riders compete in the Keirin Grand Prix each year. It is a big three-day meet held in December.
Keirin is a fast and exciting form of cycle racing.
It is a sport where riders sprint for victory on a track. In Japan, the word Keirin can mean the original local version. In other parts of the world, it refers to a modified international version. This sport is very popular with fans who enjoy watching the skill of the riders. It even involves betting on which cyclists will finish first.
Many people gather at velodromes to watch these intense races happen.
A race follows a very specific set of steps.
First, riders parade to their starting blocks and bow to the track. At the sound of a gun, they start the race. They must stay behind a pacer for three laps. This pacer might use a motorcycle, an electric bike, or even a tandem bike. The pacer starts at a slow speed and gradually goes faster.
The pacer leaves the track before the race is actually over. Then, the cyclists sprint as hard as they can toward the finish line.
The history of Keirin begins in Japan around the year 1948. It was originally created for gambling purposes. Over time, it grew into a major international sport. The men's event joined the Olympics in Sydney, Australia, in 2000. The women's event was added later for the London Olympics in 2012.
Great athletes like Jason Kenny and Shanne Braspennincx have won gold medals. The sport has many famous champions from many different nations.
Becoming a professional rider in Japan is a very hard job.
Aspiring riders must try to enter the Japan Keirin School. Only about 10 percent of people who apply are accepted. Once they are in, they must train for 15 hours every day. Riders also have different ranks to show their skill level. You can tell a rider's rank by the colors on their shorts. For example, the top nine SS class riders wear red shorts. They compete in the Keirin Grand Prix at the end of December.
Keirin connects to the wider world of professional cycling.
The Union Cycliste Internationale, or UCI, manages the world championships. These championships have included men since 1980 and women since 2002. Different countries send their best riders to compete against each other. It is a sport of speed, discipline, and great teamwork. Whether in Japan or at the Olympics, Keirin shows how much strength a cyclist can have.
Keirin is a specialized form of motor-paced cycle racing.
In this sport, track cyclists sprint for victory following a speed-controlled pacer. While the term can refer to the modified international version, in Japan, the kanji 競輪 refers to the original domestic sport. Keirin is a high-speed discipline that requires immense strength and tactical skill.
It is a major professional industry in Japan, where fans participate in betting on the outcomes. The sport has evolved from a local Japanese tradition into a prestigious global event.
A typical race follows a strict mechanical sequence.
Cyclists begin by parading to their starting blocks, where they perform a formal bow to the track. At the sound of a starting gun, they depart the blocks and settle behind a pacer. This pacer might be a motorcycle, a derny, an electric bicycle, or even a tandem bicycle.
The riders must remain behind this pacer for exactly three laps. The pacer starts at a controlled speed and gradually increases it until the final circuit. The pacer then departs the track with one or two laps remaining. This leaves the cyclists to sprint toward the finish line, sometimes exceeding speeds of 70 km/h.
Competitive racing involves different stages and complex structures. Races are conducted over several rounds, leading up to a final. Some cyclists who are eliminated in early rounds may get another chance through a process called repechages. In Japan, riders often form groups known as "lines" during the race. Within these lines, cyclists try to work together to maximize their chances of winning. The track itself is divided into specific areas, including two straightaways, four turns, and two center areas located between the corners. Referees monitor the race from towers and control rooms using closed-circuit cameras to ensure all rules are followed.
The history of Keirin is deeply rooted in Japan. It was developed around 1948 for gambling purposes and became an official betting sport in Japan that same year. In 1957, the Nihon Jitensha Shinkōkai (NJS), or Japan Bicycle Association, was founded to create uniform standards. The sport reached a major international milestone when it was admitted to the Olympics in 1996. The men's event made its debut at the 2000 Sydney Olympics. Later, the women's event was added for the 2012 London Olympics.
The professional structure in Japan is highly regulated and demanding. Aspiring riders must apply to the Japan Keirin School, but only 10 percent of applicants are accepted. These students undergo a strict training regimen of 15 hours per day. Once they pass, they are assigned a rank, starting at A3. There are six total ranks: SS, S1, S2, A1, A2, and A3.
You can identify a rider's rank by the colors on their shorts. A-class riders wear black shorts with green stripes, while S-class riders wear red stripes. The elite nine SS-class athletes wear red shorts with black stripes and special insignia.
Keirin features many significant figures and massive economic scale. In 2011, bets placed on Keirin exceeded ¥600 billion, which is approximately US$5 billion. During that same year, about 4.9 million people attended the races. Legendary athletes have defined the sport's history. Katsuaki Matsumoto holds the record for the most professional wins with 1,341 victories.
In the Olympic arena, athletes like Jason Kenny and Shanne Braspennincx have secured gold medals. These competitions demonstrate the incredible physical limits of human cyclists.
Finally, Keirin is connected to the broader world of international cycling through the Union Cycliste Internationale (UCI). The UCI organizes the World Championships, which have featured men since 1980 and women since 2002. This connection allows the Japanese tradition to interact with global standards of athleticism. The sport combines local Japanese customs, such as the formal bowing, with a highly technical, international competitive framework. It remains a unique intersection of cultural tradition, rigorous professional training, and extreme physical speed.
