Alpinista, under a textbook ride from jockey Luke Morris, became the first 5-year-old mare in 65 years to win the Prix de l’Arc de Triomphe when she saw off 3-year-old Vadeni to win the Arc by a half-length.
Winning her sixth straight Group 1, Alpinista came through as the favorite in the Arc, which was run over very soft ground under testing conditions Sunday at rainy Longchamp.
