Unnatural Ability: The History of Performance-Enhancing Drugs in Thoroughbred Racing

In Unnatural Ability: The History of Performance-Enhancing Drugs in Thoroughbred Racing, Milton C. Toby addresses the historical and contemporary context of the Thoroughbred industry's most pressing issue. While early attempts at boosting racehorses' performance were admittedly crude, widespread legal access to narcotics and stimulants has changed the landscape of horse racing, along with athletic governing bodies' ability to regulate it.

With the sport at a critical turning point in terms of doping restrictions and sports betting, Toby delivers a comprehensive account of the practice of using performance-enhancing drugs to influence the outcome of Thoroughbred races since the late nineteenth century. Paying special attention to Thoroughbred racing's purse structure and its reliance on wagering to supplement a horse's winnings, Toby discusses how horse doping poses a unique challenge for gambling sports and what the industry and its players must do to survive the pressure to get ahead.
