The fourth stage of the Giro della Valle d'Aosta, Saint-Pierre > Valsavarenche of 160.6 km, ended with the victory of Jarno Widar. A second victory in as many days for the Belgian from Lotto Development Team, who today also dedicated his triumph to the memory of Samuele Privitera.

98 riders started at 11:25, on a day characterized by four KOMs and over 4000 meters of elevation gain. The initial phase was animated by several attempts, all unsuccessful. At the intermediate sprint of Avise, the battle for the dedicated classification saw a new episode of the duel between Filippo Agostinacchio (Biesse Carrera) and Maxence Place (Wanty Nippo Re Uz), with the Aosta Valley rider preceding the Belgian.

Among the most active to note was Slovenian Jakob Omrzel (Bahrain Victorious), who passed in the lead at the KOM of Cerellaz and finished second at the KOM of Champremier behind Jarno Widar (Lotto Development Team). Omrzel and Widar were part of the leading group that fought for victory in the final climb where there were several attempts: among the most active were Danish rider Kevin Biehl (General Store), Italians Matteo Scalco (VF Group Bardiani CSF Faizanè) and Edoardo Zamperini (Arkea B&B Hotels).

Everything was decided in the final kilometers where Jarno Widar, after setting the pace for a long time, attacked and crossed the finish line with 9" over Jakob Omrzel, Irishman Liam O'Brien (Lidl-Trek) at 15", Ecuadorian Mateo Pablo Ramírez (UAE Team Emirates Gen Z) at 27" and Matteo Scalco at 29".

In the general classification, Widar leads with 3'01" over Frenchman Jean-Loup Fayolle (Arkea B&B Hotels), 3'02" over Ramírez, 3'32" over Irishman Jamie Meehan (AVC Aix en Provence Dole) and 4'13" over Matteo Scalco.
