Valverde retains lead after Sosa claims stage three win in Route d'Occitanie
Team Ineos' Ivan Sosa claimed victory in the third stage of the Route d'Occitanie.
The stage was a gruelling effort even for specialist climbers, with five particularly taxing passages.
21-year-old Colombian rider Sosa claimed victory by launching a sprint to pull away from Spaniard Valverde, who was unable to pull him back in.
Fellow Colombian Rigoberto Uran (EF Education) was three seconds behind in third position.
Valvedre made a late effort to take the win in the penultimate stage but Sosa was able to hold him off.
The fourth stage is held on Sunday, with a 154.8km race from Gers-Astarac Arros to Clermont-Pouyguilles.
Valverde takes an eight second lead over and a 17 second advantage over Uran.
