Twelve celebrities head into the wilds of the Scottish Hebrides.
Chief Instructor Ant Middleton and his team of Directing Staff (DS) apply pressure through a series of gruelling tasks and interrogations that will test the recruits both physically and mentally.
The celebrities taking part in this year's series - filmed in late 2020 - are:
-Alexandra Burke (Singer)
-Saira Khan (TV presenter)
-Ulrika Jonsson (TV presenter)
-Kerry Katona (Performer)
-Jake Quickenden (TV personality)
-Ore Oduba (TV presenter)
-James Cracknell (Olympian)
-Wes Nelson (Reality star)
-Shanaze Reade (Sportswoman)
-Kieron Dyer (Former Footballer)
-Aled Davies (Paralympian)
-Vicky Pattison (TV personality)
In the first episode, the recruits tackle the 'trainasium' - an aerial assault course designed to test how candidates manage fear. As the recruits get to know each other and relationships form, some of them are already feeling the pressure of the course.
Saira Khan said: "There are things that I have done in my life to prove myself, that I am strong, brave, determined, and a go-getter. But Celebrity SAS: Who Dares Wins was an experience which has changed my life for the better. It humbled me and I am grateful for the show for waking me up to my life and start enjoying and appreciating everything I have worked so hard to achieve. It’s been life-changing."
Shanaze Reade said: "I wanted to strip myself bare and see the work that I’d done on myself. I wanted the mental challenge and the physical challenge and it was the perfect show."
Kieron Dyer said: "I was a glass half empty kind of guy. Fear is what set us back. Going on this show was always going to be great from a mental point of view. The DS put their life on their line and it was great to learn from them."
Vicky Pattison said: "Being a big fan of the show I wanted to push myself to get out of my comfort zone and to do something completely new. Nothing can prepare you for it, and it was an experience I'll never forget."
Celebrity SAS: Who Dares Wins begins Sunday 29th August at 9pm on Channel 4.
