Series 2

The recruits face a terrifying 50-metre free-fall off a cliff, followed by boxing with a twist. Katie Price must cope with the pressures of past and present. Tony Bellew battles with his inner demons.

In the second selection phase, the celebs face murderball, a brutal beasting, a backwards helicopter dive into near-freezing waters, and a few home truths. But who will make it through?

The celebs are put in specially selected pairs. They must eat, sleep and operate as a duo. Joey Essex and paralympian Lauren Steadman may shine as individual players, but can they do teamwork?

The recruits face a killer 48 hours primed to expose the weakest members - including a beach beasting in near-freezing water and a gruelling race across mountainous terrain.

The remaining celebs face a punishing race across land and ocean before they plunge into an overnight pursuit by an elite hunter force across the Scottish Inner Hebrides.

As the climax of the current series, the last six celebs go through 48 hours of torture for the interrogation phase. Only the physically and mentally elite will make it to the end.
