Prix Greffulhe
On his first appearance of 1991, Toulon was stepped up in class for the Group Two Prix Greffulhe at Longchamp, in which he was ridden for the first time by Pat Eddery. He took the lead in the straight but was overtaken by Suave Dancer who won comfortably by four lengths, with Toulon in third. With Suave Dancer being aimed at the Prix du Jockey Club, Toulon's connections targeted The Derby and sent him to England for the Chester Vase on 7 May. Eddery held up the French-trained colt for a late challenge, but struggled to obtain a clear run and was badly hampered before Toulon broke clear to win easily from Luchiroverte.
