Tom Rolfe was one of the best American sons of the undefeated Italian champion Ribot. His dam was Pocahontas, from whom he takes his name (the historical Pocahontas's only child was named Thomas). His half-siblings include the talented racehorse and sire Chieftain (a son of Bold Ruler).
A small horse, Tom Rolfe stood 15.2 hands and weighed less than 1,000 pounds.
His sire, Ribot, won back-to-back runnings of the Prix de l'Arc de Triomphe, and Tom Rolfe was shipped to Longchamp Racecourse in Paris, France to contest the 1965 Arc. He disputed the lead until the closing stages and finished sixth on the grass course to Sea-Bird, but that result remains one of the best by an American-trained entry in that championship race.
Tom Rolfe stayed in training as a four-year-old in 1966. His wins included carrying 127 pounds to victory in the Aqueduct Handicap in September.[5]
