The Duel on the Downs was the name given to the 2011 running of the Sussex Stakes horse race.
The race featured a clash between the undefeated three-year-old Frankel and the leading older miler Canford Cliffs.
The races nickname derived from the fact that the racecourse is situated on the South Downs.
Frankel, trained by Henry Cecil at Newmarket and ridden by Tom Queally started the 8/13 favourite.
During his winning sequence, Canford Cliffs had decisively defeated many top horses including Goldikova, Xtension, Makfi, Rip Van Winkle, Twice Over and Cape Blanco.
