The American, this time around far from a domestique role, showed the climbing level that was superior to everyone else in the race besides his teammates. All of this culminated on stage 17 which finished atop the brutal Alto de l'Angliru. Primoz Roglic had been seeking a GC victory and dropped Kuss when the trio rode isolated in the head of the race - and Vingegaard followed. Kuss was ultimately caught by
Mikel Landa. Whilst in such a climb the slipstreaming effect would not be meaningful, Kuss followed Landa's wheel and lost only 19 seconds on the day which allowed him to keep the red jersey.
"I thought I had lost the jersey. Landa will never have to pay for his own beer again," Kuss said in the All In documentary jokingly. Kuss went on to then win the race as the team unanimously decided to keep the standings as they were, rewarding the American with an incredible and career-changing victory.
