With over 30 kilometres (19 miles) of the race remaining Ávila attacked on his own and soloed to a stage win, holding off the chasing peloton who finished 43 seconds behind.

The early part of the race featured a breakaway from which, with 10 kilometres (6 miles) remaining, there was just one survivor – Nikodemus Holler of Bike Aid.

Soon afterwards, overall leader Edwin Ávila (Team Illuminate) was dropped by the small leading group and with 6 kilometres (4 miles) remaining a pair of riders – Daniel Jaramillo (UnitedHealthcare) and Gabriel Reguero (Differdange–Losch) – attacked.

A counter-attack from Egan Bernal (Androni–Sidermec–Bottecchia) saw him catch and then pass the two escapees, and he continued to build a lead over the chasing group.

[11] An early breakaway of five riders, including the leader of the mountains classification, Moritz Fußnegger (0711 / Cycling) built up a lead of around 7 minutes.

By the penultimate climb at Jina, the remainder of the breakaway had a 1' 30" advantage over the chasing peloton, before being caught and passed by two attackers – Simon Pellaud (Team Illuminate) and Andrea Borso (Adria Mobil).

This pair in turn were caught by a small group of riders with 10 kilometres (6.2 miles) remaining and from that group it was once more Egan Bernal (Androni–Sidermec–Bottecchia) who attacked in the closing stages, and with the rest of the riders unable to respond, claimed his second successive stage victory, further extending his overall lead.

The most important was the general classification, which was calculated by adding each cyclist's finishing times on each stage.
