Grand Tours
The most famous cycling race is the Tour de france, a multi-stage tour over three weeks nominally through France, traditionally ending in Paris. Similar long multi-stage tours are held in Italy (the Giro D'Italia) and Spain (the Vuelta a Espana). These three races make up the "Grand Tours".
The historian Wlodzimierz Golebiewski says: "Cycling has become a major event on the Olympic programme... Like many other sports it has undergone several changes over the years. Just as there used to be track and field events such as the standing high jump or throwing the javelin with both hands, cyclists, too, used to compete for medals in events which today have been forgotten; for example in Athens in 1896, they attempted a 12-hour race, and in London, in 1908, one of the events was a sprint for 603.49 metres (660 yards)." [3] The Olympic Games has never been as important in road cycling as in other sports. Until the distinction ended, the best riders were professionals rather than amateurs and so didn't take part. [4]
Professional racing is governed by the Union Cycliste Internationale. In 2005 it instituted the UCI ProTour to replace the UCI Road World Cup series. While the World Cup contained only one-day races, the ProTour includes the Grand Tours and other large stage races such as Tour de Suisse, Paris-Nice and the Critérium de Dauphiné Libéré.
The former UCI Road World Cup one-day races - which include all five Classic cycle races or 'Monuments' - are also part of the ProTour: Milan-Sanremo (Italy), Ronde van Vlaanderen (Belgium), Paris-Roubaix (France), Liège-Bastogne-Liège (Belgium) and Amstel Gold Race (Netherlands) in the spring, and Clásica de San Sebastián (Spain), HEW Cyclassics (Germany), Züri-Metzgete (Switzerland), Paris-Tours (France) and Giro di Lombardia (Italy) in the autumn season.
