Australia's Tour Down Under is one of the most famous cycling races, along with La Primavera, the world's longest one-day race from Milan to San Remo, Italy, and the Ronde van Vlaanderen in Flanders, Belgium. In addition to the Tour de France, the Giro d'Italia and the Vuelta a España comprise Europe's three Grand Tour races. Three U.S. races, U.S.A. Pro Cycling Challenge and Tours of Utah and California, have International Cycling Union's HC status, which indicates an extreme climb.
The Tour de Suisse, held in June in the Alps, follows the Giro d'Italia and serves as a warm-up prior to the year's last Grand Tours, the Tour de France in July and the Vuelta in September. For the first time, the International Cycling Union's Asia Tour 2015 included a men's staged race in Abu Dhabi, organized by RCS Sport, which runs the Giro d'Italia.
The biggest race in Asia since 1996 is the Tour de Lagkawi. The Lagkawi has an HC rating and attracts international racers.
The HC-rated Arctic Race of Norway takes place entirely above the Arctic Circle. The Paris to Nice, France, race, also known as the Race to the Sun, is a spring race, first run in 1933, and a highly coveted title among professional bicycle racers. The Tour of Alberta race, part of the International Cycling Union's America Tour, is a seven-stage race, first run in 2013.
