Chaves was part of a four-rider breakaway that moved clear of the field after the penultimate climb, and although he was beaten to the line by Warren Barguil and Mattia Cattaneo, Chaves's third place, coupled with a 24-second time gap to the field, allowed him to win the race by 17 seconds.

Team Sky team-mates Rigoberto Urán and Sergio Henao animated the field on the final climb to Lagunas de Neila, and only Chaves was able to follow the pair; Chaves ultimately beat his former team-mate to take his first professional victory on the line, and allowed him to finish the race in third place overall.

[16] The following weekend, Chaves took victory in the Gran Premio Città di Camaiore in Italy, from a five-rider group, after forming the group with Italian national champion Franco Pellizotti of the Androni Giocattoli–Venezuela team, on the Monte Pitoro climb.

[20] Chaves lost the race lead on stage 5, as he was caught out in a split in the peloton at the finish and dropped 6 seconds to Dumoulin.

[21] However, on stage 6 Chaves attacked 2 kilometres (1.2 miles) from the summit of the final climb to Sierra de Cazorla and held off Dan Martin (Cannondale–Garmin) and Dumoulin by five seconds for his second stage win and retake the race lead.

[26] He struggled at the event, eventually finishing 62nd in the general classification, almost two-and-a-half hours down on winner Chris Froome.

He broke away from the peloton at the final ascent of the penultimate stage, taking the victory and the lead in the overall classification.
