 On 13 December 2016, the International Bobsleigh and Skeleton Federation announced that it would relocate the event.Some athletes were concerned that they might unwittingly ingest a banned substance if the host tampered with food or drinks, while others "were worried about the evidence that Russian laboratories had been opening tamper-proof bottles.If they have opened these bottles to help their athletes, what is to stop them also opening them to tamper with samples from any athlete in the competition?"
