Book excerpt: Some of horse racing's most respected authorities looked at feats of greatness, world records, legendary rivalries, and innovations to rank the sport's top 100 moments. They weighed individual accomplishments against industry initiatives, innovations against lucky breaks to come up with the definitive list. They pondered Secretariat's 31-length Belmont Stakes victory, Smarty Jones' elusive Triple Crown, the creation of the Breeders' Cup, and advancements in equine surgery. Racing's top 100 list will generate debate for years to come, just as did the ranking of Man o' War over Secretariat as Horse of the Century. Richly illustrated with historic and modern photos, Horse Racing's Top 100 Moments also contains comprehensive lists of leading earners, fastest times, highest prices, and most races won.
