Prix d'Été (English: Summer Classic) is a horse racing event for four-year-old Standardbred pacers held annually in Canada, at Hippodrome 3R of Trois-Rivières, Quebec.

This event was held for the first time in 1966 under the name of Prix d'Automne (Autumn Classic) at the now defunct Blue Bonnets Raceway in Montreal.

In 1967 the race was renamed the L'Amble du Centenaire (Centennial Pace) in honor of Canada's 100th anniversary and made open to pacers age three and older.

Taken over and operated by the provincial government agency SONACC (Société nationale du cheval de course), but eventually withdrew its support and placed their operating company under bankruptcy protection on October 13, 2009, and permanently closed the facility.
