The show returns putting more people through the SAS selection process. For the first time female recruits are joining the men with no allowances or exceptions made for them. The opening round comes from the Chilean Andes.
The remaining male and female participants face further gruelling challenges designed to test both their mental and physical strength -including a 200-foot forward abseil and the infamous boxing task.
The remaining recruits are tasked with crossing a 200-metre gorge, swimming under the ice on a frozen lake and navigating a perilous valley at night while trying to avoid capture by a local force and their dogs.
