Vuelta a Suiza
The race was first held in 1933 and has evolved in timing, duration and sponsorship. Like the Tour de France and the Dauphiné, the Tour de Suisse has several stages with significant mountain climbs in the Swiss Alps and at least one individual time trial. Several winners of the Tour de Suisse have also won the Tour de France, including Eddy Merckx and Jan Ullrich. In 2005 the Tour de Suisse was included in the inaugural UCI Pro Tour and organizers moved the race to earlier in June.
