Alto El Amago, Argentina — Stage 4 was a 168.7-kilometer race from El Potrero De Los Funes to Cerro El Amago, a category one summit finish featuring an average gradient of 7.2 percent. The race began with an early break of five riders that was reeled back before the peloton hit the slopes of the Cerro El Amago.
As expected, the final climb splintered the peloton into groups. Nairo Quintana (Movistar) soloed to the win ahead of Sergio Godoy (San Luis Somos Todos) and Darwin Atapuma (BMC Racing Team). Javier Megias was Team Novo Nordisk’s top finisher in 50th. The 30-year old Spanish rider is now the team’s best-placed rider in 46th, 15:30 behind defending race leader Phillip Gaimon (Garmin Sharp).
On Friday, the world’s first all-diabetes pro cycling team races against the clock in an individual time trial. The 19.2-km stage takes place around downtown San Luis.
