The third stage of the 59° Giro Ciclistico Internazionale della Valle d'Aosta - Mont Blanc with its 138 kilometers and its 3500 meters in altitude gain the riders from Saint Vincent to the dam of Place Moulin of Bionaz.
The first significant action of the day is recorded at the bottom of the climb of Perloz with a quartet of athletes consisting of Daniel Lima (Israel Premier Tech), Roman Ermakov (Cycling Team Friuli), Alex Bogna (Alpecin Deceuninck) and Martin Tjotta (Bourg Ain) who launches the attack. Their action will distinguish the whole first part of the race with the group of the best to control. The star of the race, therefore, is Roman Ermakov who wins in the order the first GPM of Perloz, the Sprint Catch of Montjovet, the GPM of Payé and the Sprint Catch of Saint Christophe. The last meters of the climb of Allein, however, see the attack of Tjotta that passes at the front of the GPM. Behind, as for the first of the general ranking, nothing to report with the large group of the best to control themselves. The only sortie, before Doues, is the one of Davide De Cassan (Cycling Team Friuli), more than ever willing to recover the ground lost in the general classification in the second stage. The rider from Trentino, then, launches in pursuit of the four fugitives towards the finish line, reaching all the riders in front except for the Norwegian Tjotta who defends with his teeth his leadership. The final is uncertain until the end, therefore, with Tjotta who prevails with only 12 seconds ahead of De Cassan and 21 seconds over Bogna. Behind them the big ones fight only in the last kilometers of the final ascent and get close to the podium with Isaac Del Toro (Monex) ahead of Darren Rafferty (Hagens Berman) and Alexy Faure Prost (Circus King Uz). The yellow jersey Eaux Valdotaines David Golliker (Groupama FDJ) has som slight difficulties but manages to maintain the leadership in the general classification, followed by Faure Prost and Darren Rafferty (Hagens Berman). After this stage, the leader jerseys are on the shoulders of David Golliker ( yellow Eaux Valdotaines and white of the young Matterhorn Ski Paradise), Martin Tjotta ( a pois CVA climbers), Alexy Faure Prost (blue Aosta Valley Region points) and Roman Ermakov (red Haute Savoye Le Département).
