Heroic was sired by Valais (by the 1905 Epsom Derby winner, Cicero), his dam was Chersonese (GB) by Cyglad. This made him inbred twice in the 3rd generation to Cyllene and in the 3rd and 4th generations (4x3) to Illuminata through the half-sisters Gas, dam of Cicero and Chelandry. Heroic was a brother to the useful sire, Thracian and a half-brother to the stakeswinner, Cimbrian.^[3]

Heroic was an outstanding type of yearling that fetched the top price of 1,800 guineas at the Inglis’ bloodstock sales.^[2]

He was trained by Jack Holt who posthumously would become part of the 2001 inaugural class inducted in the Australian Racing Hall of Fame.

Following this race Heroic’s nominations for the VRC Derby and Melbourne Cup were rejected. This was as a result of Heroic’s connections being disqualified because of their failure to allow a stable-mate to race on his merits.^[4]

In February 1925, C.B. Kellow paid 16,000 guineas, a record price, for the great Heroic, who won a number of races for him afterwards including his only other win for the season, the weight for age (w.f.a.) AJC Autumn Stakes over 12 furlongs.^[2]
