An avid sportsman, Whitney was a ten-goal
polo player. His love of the sport was inherited from his father, who had been involved with polo when it was first organized in the United States in 1876 by
James Gordon Bennett, Jr. Whitney organized the U.S. polo team that beat
England in 1909. "Whitney Field" polo field near
Saratoga Springs, New York, is named for him. He was a board member of the
Montauk Yacht Club and competed with his yacht
Vanitie in the
America's Cup. Whitney also served on the board of directors of the
Long Island Motor Parkway, built by his wife's cousin,
William Kissam Vanderbilt II.
Thoroughbred horse racing Whitney was a major figure in
Thoroughbred racing and in 2018 was voted one of the
National Museum of Racing and Hall of Fame's most prestigious honors as one of the
Pillars of the Turf. Harry Whitney inherited a large stable from his father including the great
filly Artful and her sire
Hamburg, and in 1915 established a
horse breeding farm in
Lexington, Kentucky where he developed the American polo pony by breeding
American Quarter Horse stallions with his thoroughbred mares. He was thoroughbred racing's leading owner of the year in the United States on eight occasions and the breeder of almost two hundred
stakes race winners. His leading sire was first Hamburg and then the great sire
Broomstick, by
Ben Brush. His
Kentucky-bred horse
Whisk Broom II (sired by Broomstick) raced in
England, then at age six came back to the U.S. where he won the
New York Handicap Triple. He also owned
Upset, who gave
Man o' War the only loss of his career. Whitney had nineteen horses who ran in the
Kentucky Derby, winning it the first time in 1915 with another Broomstick foal,
Regret, the first
filly ever to capture the race. Regret went on to earn Horse of the Year honors and was named to the
National Museum of Racing and Hall of Fame. Whitney won the Kentucky Derby for the second time in 1927 with the colt
Whiskery. His record of six wins in the
Preakness Stakes stood as the most by any breeder until 1968 when
Calumet Farm broke the record. Whitney's colt Burgomaster won the 1906
Belmont Stakes and also received Horse of the Year honors. Among the many horses, Whitney's breeding operation produced
Equipoise and
Johren. Whitney's stable won the following prestigious
