Defending champion Kamil Stoch won the tour again after he was victorious in all four competitions and thus repeated the success of Sven Hannawald , who was the first jumper to win all four competitions in 2001/02 .
The number of athletes that the nations are allowed to start depends on the previous season results. In addition, the host nations Germany (in Oberstdorf and Garmisch-Partenkirchen) and Austria (in Innsbruck and Bischofshofen) will send a national group of six athletes each to the start. The following 83 ski jumpers were nominated:
GermanyGroße Olympiaschanze (HS140)
The qualification for the second competition in Garmisch-Partenkirchen, the so-called New Year’s competition , took place on December 31, 2017. This was won by Johann André Forfang ahead of Dawid Kubacki and Stefan Hula .
AustriaBergiselschanze (HS130)
The qualification for the third competition in Innsbruck took place on January 3rd, 2018. The day before, the French team announced that their ski jumpers Jonathan Learoyd and Vincent Descombes Sevoie would no longer compete in the second half of the Four Hills Tournament. In the qualification, Gregor Deschwanden and Antti Aalto finished in 50th place with equal points. According to a rule that is only valid for KO jumping, the jumper with the higher starting number (Deschwanden) qualified for the competition on the following day. The US team, consisting of Michael Glasder , Kevin Bickner and William Rhoads , who wanted to take part in the tour from Innsbruck, had to cancel its start in the qualification at short notice because their luggage including skis was misdirected when arriving by plane.
The competition was held on January 4th, 2018. This was the third competition in a row to be won by Kamil Stoch , ahead of Daniel-André Tande and Andreas Wellinger . Richard Freitag , who had been Stoch's biggest competitor in second place in the overall standings up to Innsbruck, fell when landing his jump to 130 m in the first round and was taken to the hospital because of severe hip pain. After the fall, national coach Werner Schuster and Horst Hüttel , sporting director of the DSV, strongly criticized the technical delegate of the FIS, Geir Steinar Loeng , who, in view of the weather conditions, had again chosen too long a run-up length after Svenja Würth had already participated in the women's World Cup in Hinterzarten had fallen badly a few weeks earlier for the same reason. One day later, Friday announced in consultation with the German team doctor Mark Dorfmüller that he would not start in Bischofshofen.
AustriaPaul-Ausserleitner-Schanze (HS140)
The qualification for the final, fourth competition in Bischofshofen, traditionally also called Dreikönigsspringen , took place on January 5th, 2018. The competition was held on January 6, 2018.
After all four jumps, the points of the jumpers from all four jumps are added up. The jumper with the highest number of points is the overall winner of the tour.
For the first time, a high-speed camera and chip system was used on the jump skis during the tour in order to be able to process more precise data on the quality of the jump of the ski jumpers for spectators and athletes.
