Celebrity SAS: Who Dares Wins for Stand Up to Cancer S03E04 - Episode 4

The recruits take on the `redman" challenge, featuring hand-to-hand combat against their trainers, the DS (Directing Staff). Kieron Dyer catches the eye with his strength, but the DS want to know where he's at mentally. Next, the recruits are required to run down a 50m-high pillar face first. Alexandra Burke is still standing but struggling with her confidence. Later, it's the open-water task, where the recruits must dive nine feet deep in low visibility and open a crate of essential supplies.
