Secretariat

Secretariat didn't just win the Kentucky Derby; he made it look like the other horses were out for a casual stroll. This horse was so fast, rumor has it he needed a parachute to slow down after races. Fans are still trying to calculate if he had turbo boosters hidden somewhere. Picking any other horse over him in the 'Greatest Kentucky Derby Winners of All Time' feels like claiming a tricycle could win the Tour de France.
