Grundy's famous defeat of Bustino in the 1975 King George VI And Queen Elizabeth Stakes is the inaugural recipient of the Qipco King George Diamonds & Pearls award.
It is 40 years since the contest dubbed "the race of the century" and to mark the anniversary, Qipco and Ascot commissioned a three-minute film featuring original archive footage of the race together with newly-recorded interviews with Grundy's trainer Peter Walwyn and Bustino's jockey Joe Mercer.
At a celebration of the race at Kensington Roof Gardens, Walwyn was presented with a print celebrating Grundy's victory, featuring memorabilia and newspaper cuttings from the race.
The Qipco King George Diamonds & Pearls award will annually honour a vintage running of Ascot's midsummer showpiece.
Walwyn said: "I knew we were on the verge of greatness (with him) and it was the King George that brought the greatness out."
Mercer said: "I feel very proud to be associated with that particular race because it was the race of the century."
