The first Giro d'Italia was held in 1909, and the 2009 route was designed to commemorate the 100th anniversary, though interruptions due to World War I and World War II meant this was only the 92nd race. Milan, which had for years been the city in which the Giro concluded, was the site of a ten-lap criterium on the same circuit that began the first Giro d'Italia. Every city that hosted a stage start or finish in the first Giro was visited in 2009 with the exception of Genoa, although Arenzano (in the province of Genoa) hosted the finish to stage 11. The 11th stage also went over the Passo del Turchino, a climb used every year in the classic cycling race Milan-San Remo.
