Prix Greffulhe
Bigstone, who had raced twice at two, finishing second on each occasion, made a winning reappearance at three in the Listed Prix Omnium over 1600 metres at Saint-Cloud on 30 March. A month later he was moved up in class and distance for the Group Two Prix Greffulhe over 2100 metres at Longchamp Racecourse. Ridden by Dominique Boeuf, he finished second to the André Fabre-trained Hunting Hawk. He was then moved up to Group One class and sustained two narrow defeats: he was beaten a neck by Le Balafre when favourite for the Prix Jean Prat and finished second by a nose by Fort Wood in the Grand Prix de Paris.
