Thoroughbred horse racing involves significant catastrophic and cumulative injury risk; welfare reform efforts focus on surface safety, medication regulation, and racing age restrictions.
Catastrophic injury represents the most acute welfare outcome in racing, but cumulative musculoskeletal stress, repetitive high-speed training, and pharmaceutical intervention represent ongoing welfare costs across racing careers. Horses that survive racing careers may have chronic joint disease and ongoing pain management requirements. The economics of racing create incentives to race horses before they are physically ready, to mask pain with medications that enable unsound horses to train and race, and to prioritize performance over long-term soundness. Structural reform requires aligning economic incentives with welfare outcomes.
