Alejandro Marque suffered a mechanical halfway up the climb seeing his podium ambitions slightly shortened, as Glassdrive rode to set up an attack in the final five kilometers by Frederico Figueiredo. The Portuguese climber quickly got a gap, as teammate and yellow jersey Mauricio Moreira cracked and lost contact with the chasing group.
Although the Uruguayan managed to recover ground and return to the group with his rivals, Figueiredo was far up the road as he took the stage win and 37 seconds on the road, becoming the new yellow jersey. Henrique Casimiro and
Luís Fernandes rode to second and third place on the day.
