National Geographic : 1974 May
Charging toward history, last year's Triple Crown winner Secretariat (above, third from right) bursts late from the starting gate in the Kentucky Derby. His number, 1A, indicates that his trainer, Lucien Laurin, has another horse in the same race. Giant 25-foot strides help Secretariat make up the lost yardage. Virginia-born but Bluegrass-sired, he blazed over the 1 1 /4 -mile course in 1 min ute, 592/5 seconds-a new Derby record. Putting her money where her mouth is, a sun-splashed blonde tries to register a bet with a friend (left). Crowding the stands and the infield, 134,476 people filled Churchill Downs for the 1973 Derby; they wagered more than three million dollars on the event. Racing colors garb a hopeful bettor at Keeneland (right). Scratch sheet in hand, he watches the Thoroughbreds enter the track, seeking a clue to the horses' for tunes-and his own.
