The Racing Plate — Design and Weight

A Thoroughbred racing plate typically weighs 50–100 grams on the front feet — compared to 150–250 grams for a standard steel shoe. This weight saving matters enormously: research on racing Thoroughbreds estimates that each 100 grams of additional shoe weight costs approximately 1 length (about 2.4 meters) over a mile. The aluminum alloy used in racing plates is far stronger than pure aluminum, but still softer than steel — plates wear quickly on pavement and non-racing surfaces, which is why Thoroughbreds are walked from the barn to the track on rubber mats wherever possible. Plates are replaced at every shoeing cycle, typically every 2–3 weeks at a working stable.
