The early going of the 177km 10th stage from Salamanca to Fermoselle was animated by a two-rider breakaway that featured Tiago Machado (Katusha-Alpecin) and Jesus Ezquerra (Burgos-BH). The duo built up a lead of four minutes on the peloton, but the flat parcours, which included just one category 3 climb about 30km from the finish, didn't lend itself to a breakaway day. The peloton caught the pair as they ascended the the Alto de Fermoselle, setting up the sprint finale.
Despite a spate of punctures in the closing kilometres that affected several general classification contenders, little changed at the top of the overall standings, as Mitchelton-Scott's Simon Yates continues to lead Movistar's Alejandro Valverde by one second, with Nairo Quintana at 14 seconds in third place overall.
