Tadej Pogacar won a line race against his main competitors because he claimed the first stage of the du dauphine standard.
Slovenini finished the mountains 196 km from Domeraat to Montlucon in four hours 40 minutes and two.
The Emirates-XRG Rider Pogacar team, which won the Tour De France last year, accelerated the Dutchman Matthew Van der Boyle with only 25 meters to go to victory.
Jonas Fengdard came from Team Visma-Ereease in Denmark in second place, where Van der Boyle ranked third and Remco Evenepoel in Belgium in fourth place.
The standard will compete for the standard of eight stages, which includes a time trial, where the Dragon prepares the start of the France bicycle race on July 5.
