Robert Johansson wygrał pierwszą loteryjną serię treningową przed prologiem do niedzielnego konkursu Raw Air na mamucie w Vikersund. Rekord życiowy ustanowił Stefan Hula, który lądował na 226 metrze. Druga seria padła łupem Markusa Eisenbichlera.
W pierwszej serii treningowej najlepszy był reprezentant gospodarzy oraz vicelider cyklu – Robert Johansson. Norweg poszybował na 240,5 m z 4. belki startowej i wyprzedził o 20 punktów Stefana Krafta (235,5 m / 8. belka). Trzecie miejsce zajął Noriaki Kasai (236,5 m / 7. belka). Tuż za wymienioną trójką znaleźli się bracia Prevc – Peter (235 m. / 8. platformy) i Domen (235,5 m / 8. belki).
Najlepszym Biało-Czerwonym był Stefan Hula, który lotem na 226 metr z 8. platformy startowej ustanowił swój nowy rekord życiowy i zajął szóste miejsce. Wiatr w plecy towarzyszył Kamilowi Stochowi, który wylądował na 206 metrze i był 11. 15. miejsce zajął Dawid Kubacki (213,5 m), 28. Maciej Kot (194,5 m), 29. Piotr Żyła (199 m) i 51. Jakub Wolny (102 m).
Aż dwanaście razy jury decydowało się zmienić rozbieg. Zawodnicy startowali z 12., 10., 7., 9., 11., 13., 9., 11., 14., 12., 8., 7. i 4. belki.
II trening:
Drugi trening rozpoczął się z 10 minutowym opóźnieniem spowodowanym zbyt mocnymi podmuchami wiatru.
Markus Eisenbichler 241 metrowym lotem z 8. belki startowej zapewnił sobie wygraną w drugiej serii treningowej. Niemiec pokonał Roberta Johanssona (230,5 m / 9. belka) o 8,6 pkt oraz Daniela Andre Tande (231,5 m / 9. belka). Kamil Stoch w drugim treningu poszybował na 211 metr z 6. platformy startowej i ostatecznie uplasował się za czołową trójką.
Pozostali Biało-Czerwoni spisali się nieco lepiej niż w pierwszej serii treningowej. 12. był Stefan Hula (222,5 m), 14. Maciej Kot (204 m), 22. Dawid Kubacki (198,5 m), 26. Piotr Żyła (195 m), a 38. Jakub Wolny (177,5 m).
Serię treningową rozegrano z 8., 10., 13., 9., 8., 6., 10., 8., 9. platformy startowej.
Na 17:30 zaplanowany był start prologu w Vikresund. Przez panujące warunki atmosferyczne na obiekcie, jury zdecydowało się przełożyć rywalizację na 18. Transmisja od 17:25 na Eurosport 1.
