[3] Apart from Galopin, the best of Vedette's offspring was Speculum, who won the Goodwood Cup, the Suburban Handicap, was third in The Derby, and was Britain's Champion Sire in 1878.

Genetic evidence [4] indicates that Galopin's offspring do not share the Y chromosome haplotype of the sire line to which Vedette belongs.

[3] A year later, the yearling was offered for sale again, and was bought for 520 guineas by the Hungarian aristocrat Gustavus Batthyany,[6] acting on the advice of his private trainer John Dawson.

Dawson thought so highly of the colt that he intended to run him in a trial against the five-year-old Prince Charlie, the winner of the 2000 Guineas and the leading sprinter in England.

Galopin began his three-year-old career by running a match race against a filly named Stray Shot over Newmarket's Rowley Mile course.

At Newmarket he won a £1,000 match race against the five-year-old Lowlander, the winner of the Royal Hunt Cup and the All-Aged Stakes.

Batthyany had a heart condition that enforced early retirement of Galopin as it was feared that the excitement of watching his horse race may risk the Prince's life.

[2] After the death of the Prince in 1883, Galopin was sold to Henry Chaplin for 8,000 guineas, but was not initially well received as a stallion because of the presence of Blacklock in his pedigree.

[2] In May 1886 The Sporting Times carried out a poll of one hundred racing experts to create a ranking of the best British racehorses of the 19th century.
