The fourth stage is the largest in length of this year's event. 

The riders will start from Sperchiada at the Prefecture of Fthiotida, and head east until the intermediate sprint in Lamia. From there they will change direction, heading south, to enter Viotia. Then, they will move southeast, passing the two largest cities of Viotia, Livadia, and Thebes, where two more intermediate sprints await them. 

After Thebes they will once again change direction, heading towards the northeast. The riders will tackle a cat. 3 climb in Prophitis Ilias before the final sprint in Chalkida, with the finish line placed on the city's old bridge, next to the Euripus Strait. 

A stage, in which a classic battle between the breakaway group and the sprinters is expected to unfold.
