Consigned to the 1923 yearling auction, Coventry was sold for $25,000 to New York carpet manufacturer, Gifford A. Cochran. In 1925, Coventry's training was handled by future U.S. Hall of Fame member Bill Duke who knew the colt's breeding having returned from France that year where he had been training Thoroughbreds since 1888. Duke had trained Coventry's sire Negofol for Willie Vanderbilt's racing stable and had won important races with him including the French Derby. Back home in the United States, in 1925 Duke also trained Coventry's stable mate, a colt owned by Gifford Cochran named Flying Ebony whose ability to run extremely well on muddy racetracks resulted in his winning of the May 16 rain-soaked Kentucky Derby.
Coventry made just five lifetime starts, winning once. But, the one win came in the Preakness Stakes. Ridden by Clarence Kummer, the colt went off at the longest odds of any Preakness winner in history, paying backers $45.60 for a $2 wager. That record stood for exactly fifty years until Master Derby in 1975 paid $48.80. In his next race, the Withers Stakes at New York's Aqueduct Racetrack, Coventry broke down and was retired to stud. He had very limited success as a sire. Hand To Hand and Durango were his best runners, each winning a number of minor races.
