Of Easy Jet's stamina and busy training regimen, Merrick said, "I guess he ate at night; I don't know when else. It was unbelievable the amount of energy he had". Training for the race track generally begins when a horse is a long yearling—between one and a half and two years of age. Easy Jet was so easy to train that Merrick decided to oversee the training himself rather than send the horse away to a professional trainer. In a practice race at the ranch, Merrick matched the yearling against Jet Smooth. Although his elder brother had the advantage of previous race experience, Easy Jet won the 350-yard (320 m) race. Easy Jet's performance prompted Merrick to enter him in a yearling race at Blue Ribbon Downs, which the colt won by more than a length.
