Seven of the nineteen UCI WorldTeams, five UCI ProTeams, eight UCI Continental teams, and the Slovakian national team made up the twenty-one teams that participated in the race.[5] All but two teams entered a full squad of seven riders: Adria Mobil entered six, while Cycling Team Friuli ASD entered five. In total, 144 riders started the race, of which 105 finished.[6]
For stage 1, per the race regulations, Jannik Steimle, the second-placed rider after the prologue, was assigned the green jersey of the leader of the points classification, and Marceli Bogusławski, the third-placed rider after the prologue, was assigned the polka-dot jersey of the leader of the mountains classification. However, neither rider was deemed to be officially leading those respective classifications, as no points were awarded in the prologue for either classification.[28]
On stage 2, Leon Heinschke, who was second in the young rider classification, wore the white jersey, because first-placed Eirik Lunder wore the green jersey as the leader of the points classification.
On stage 3, Peter Sagan, who was second in the points classification, wore the green jersey, because first-placed Álvaro Hodeg wore the yellow jersey as the leader of the general classification. On stage 4, Hodeg wore the green jersey, having switched positions with Sagan in both the general and the points classifications; Sagan wore the yellow jersey.
^The jersey for the Slovak rider classification will not be worn during the race; it will only be presented at the podium ceremony after every stage to the best placed Slovakian rider in the general classification.[3]
