Next year's series of SAS: Who Dares Wins will be shot in a "sub-zero location" in a major Channel 4 format switch-up, according to a telly insider.
It is rumoured to be the 'toughest series yet' as contestants get 'plunged into freezing temperatures' as they're 'pushed to breaking point'.
The source claims "brutal tasks" include "ice-water plunges, snow treks and endurance challenges" in the brand-new series.
