Milan–Sanremo, also called "The Spring classic", is an annual road cycling race between Milan and Sanremo, in Northwest Italy. With a distance of 298 kilometres (185 mi), it is the longest professional one-day race in modern road cycling in Europe. It is the first major classic race of the season, usually held on the third Saturday of March. The first edition was held in 1907.
It is traditionally the first of the five Monuments of the season, considered to be one of the most prestigious one-day events in cycling. It was the opening race of the UCI Road World Cup series until the series was replaced by the UCI ProTour in 2005 and the World Tour in 2011.
