Prix Niel
After a summer break, Flintshire returned for the Prix Niel at Longchamp on 15 September. He started 5/4 in a strong field but although he made progress in the straight he never looked likely to win and finished fourth behind Kizuna, Ruler of the World and Ocavango. On his final appearance of the year, Flintshire contested the 92nd running of France's most prestigious race, the Prix de l'Arc de Triomphe. Starting at odds of 12/1 in a seventeen-runner field he finished eighth, twelve lengths behind the winner Treve.
