So The G carries a nice piece about keirin. Why it started, gambling, place in Japanese society etc. It’s a fun piece.
Except, well, it never actually does explain what keirin is, how it works. Which is a bit odd really. From Wiki:
Riders use brakeless fixed-gear bicycles. Races are typically 1.5 kilometres (0.93 mi) long: 6 laps on a 250 m (270 yd) track, 4 laps on a 333 m (364 yd) track, or 4 laps on a 400 m (440 yd) track. Lots are drawn to determine starting positions for the sprint riders behind the pacer, which is usually a motorcycle, but can be a derny, electric bicycle or tandem bicycle. Riders must remain behind the pacer for 3 laps on a 250 m (270 yd) track. The pacer starts at 30 km/h (19 mph), gradually increasing to 50 km/h (31 mph) by its final circuit. The pacer leaves the track 750 m (820 yd) before the end of the race (3 laps on a 250 m (270 yd) track). The winner’s finishing speed can exceed 70 km/h (43 mph).
Yes, we can see why that might be attractive to gamblers. Given a program of races over a day a repeated charge of high octane excitement in those final sprints.
But The G’s piece would have been better if it had given a – shorter perhaps – explanation of what it actually is.
