Jonas Vingegaard won the fourth stage of the Itzulia thanks to a brutal attack with 20 km to go just when EF Education-EasyPost were setting a hard pace. Richard Carapaz had just tried, but with no luck, with the race leader then taking the opportunity.
Quite the opposite of what happened when Vingegaard made his attack, which no rider was able to follow in first person. Then, at his own pace, came Mikel Landa. The duo worked together all the way into the finish, where the Dane took the stage win in front of Landa.
