1953: two-year-old season

Hasty Road won two five-and-a-half furlong sprint races at Arlington Park before his first major test in July 1953, when he ran in the Arlington Futurity. He started favorite against seventeen opponents for the race that carried prize money of $157,915, making it reportedly the most valuable two-year-old race ever run to that point. Ridden by Eddie Arcaro, Hasty Road took the lead on the home turn and claimed the victory by two and a half lengths from Mr. Prosecutor and Donnajack. His winning time of 1:10.2 for six furlongs was a race record.^[9] After losing his next race, Hasty Road ran in Chicago's other valuable two-year-old prize, the $156,085 Washington Park Futurity in September. Arcaro sent the colt into the lead after a furlong and he was never headed, winning by three and a half lengths from Athenian and thirteen others.^[10]

In October, Hasty Road finished unplaced behind Porterhouse when favorite for the Belmont Futurity, being apparently unsuited by the track.^[6] He maintained his position as the year's leading two-year-old money-winner, however, with a win in the Breeders' Futurity Stakes at Keeneland Race Course and was then sent to Churchill Downs for the Kentucky Jockey Club Stakes, in which he was matched against the highly rated Fisherman. Racing over one mile, Hasty Road beat Goyamo by one and a half lengths, with Fisherman more than five lengths further back in a dead heat for fourth. Hasty Road was ridden by Johnny Adams, who became his regular jockey.^[11]

By the end of the year, Hasty Road had earned $277,132, making him the second biggest money-winner of the season among all American horses^[12] and the most financially successful two-year-old in history.^[6] He was overwhelmingly voted American Champion Two-Year-Old Colt by Turf & Sports Digest magazine.^[12] The rival Daily Racing Form and Thoroughbred Racing Association awards, however, were taken by Porterhouse, and in the Experimental Free Handicap, a ranking of the year's best colts, Hasty Road was rated two pounds behind Porterhouse and Turn-To.^[6]

1954: three-year-old season

Hasty Road began his three-year-old season in Florida, where he finished a neck second to Duc de Fer in the seven-furlong St. Valentine Purse at Hialeah on February 14.^[2] In the much more important Flamingo Stakes over nine furlongs two weeks later, he finished fifth of the nine runners behind Turn-To. During his time in Florida, Hasty Road displayed his "playful" temperament by twice throwing his exercise rider, sustaining minor injuries which delayed his training schedule.^[7]

Hasty Road returned to racing when he ran fifth in a seven-furlong allowance race at Keeneland on April 16. At Churchill Downs eleven days later, he was matched against leading Californian colt Determine in the one-mile Derby Trial Stakes. Running in blinkers for the first time, Hasty Road returned to his best form to beat Determine by a head in a track-record time of 1:35.0. The win emphasised his prospects in the Kentucky Derby, as the last two winners of the Trial, (Hill Gail and Dark Star), had taken the first leg of the Triple Crown.^[13] Four days later, Hasty Road started the 5/1 fourth favorite for the Derby, with the Californian colts Correlation and Determine being first and second choices. Johnny Adams sent Hasty Road to the front from the start and held a clear advantage into the straight. Determine, however, emerged from the pack to challenge Hasty Road, took the lead one sixteenth of the mile from the finish, and won by one and a half lengths.^[14] Adams later claimed that Hasty Road was distracted by the crowd on the infield and lost concentration in the straight.^[15]

With Determine ruled out of the remaining Triple Crown races, the meeting of Hasty Road and Correlation in the Preakness Prep at Pimlico Race Course on May 18 seemed likely to decide the Preakness Stakes favorite. As at Churchill Downs, Adams attempted to lead all the way on Hasty Road, but Correlation caught him in the closing stages and won by a head.^[15] In the Preakness Stakes six days later, Hasty Road started 9/2 second favorite behind Correlation in front of a crowd of 29,604. Adams employed his usual tactics, leading from the start on Hasty Road until Willie Shoemaker moved Correlation to challenge him in the straight. The finish was closely contested and rough, with bumping between the two leaders as Hasty Road moved away from the rail and the third-placed Hasseyampa being obstructed when trying to make a forward move. At the wire, Hasty Road prevailed by a neck, but the result was only confirmed fifteen minutes later, after the racecourse stewards scrutinised replays of the finish.^[16] After the race, Adams, who had won his first Triple Crown race at the age of thirty-nine, said that he only used his whip once, at the top of the stretch, while Reuben paid tribute to the colt's courage, saying that he "hangs on like a bull dog".^[17]

Hasty Road never recovered his Preakness form and his results were mixed as the season progressed. Reuben had originally planned to miss the Belmont, feeling that the track and the distance would not suit the colt, but changed his mind after the Preakness.^[8] Hasty Road was sent to New York for the Belmont, but after the colt worked on the track, Reuben had another change of heart shortly before the race and returned him to his base in Chicago.^[18] On June 26 at Arlington Park, Hasty Road won the seven-furlong Warren Wright Memorial from off the pace by a length, with Hasseyampa third. At the same track in July, he started favorite for the Arlington Classic but never recovered from a poor start^[19] and finished fifth to Errard King. In the following month's American Derby, Hasty Road again lost to Errard King, tiring in the closing stages and losing second place to the Belmont Stakes winner, High Gun. In October, Hasty Road ran third to Helioscope in the Benjamin Franklin Handicap at Garden State Park and then finished last of the ten runners behind Chevation in the Yankee Handicap at Suffolk Downs. Hasty Road returned to the scene of his Preakness win in November but finished unplaced behind Helioscope in the Pimlico Special.

1954: four-year-old season

As in 1953, Hasty Road began his year in Florida. In January at Hialeah, he recorded his first win for seven months when he carried 123 pounds to victory in a six furlong handicap race. He then took the Abraham Lincoln Purse at the same course at one mile and one-eighth, before carrying 122 pounds the $132,800 Widener Handicap on February 19. Rather than urging Hasty Road into a clear lead as he had often done in the past, Adams allowed the temperamental colt to set his own pace. Hasty Road led the race at a modest pace and turned into the stretch with a slight advantage over Capeador and Ram o' War. Although he drifted out slightly from the rail, Hasty Road appeared to have no difficulty maintaining his advantage, and Adams did not need to resort to his whip to hold off Capeador and win by a neck. An objection to the winner by Hedley Woodhouse, the rider of the runner-up, was dismissed by the racecourse stewards. Hasty Road's third straight win.^[20] On March 16, Hasty Road sustained an injury in training at Hialeah which was described as either a "wrenched left foreleg",^[21] or a "filled ankle".^[22] The horse was expected to return to the track in the summer; he finished third in his comeback and was retired to stud.
