Stepping it up from I'm A Celebrity...Get Me Out Of Here! is the Channel 4 show Celebrity SAS: Who Dares Wins. Here celebrities undergo gruelling and intense training, similar to that of the special forces.
Taking part in the 2022 series is the sprinting athlete Dwain Chambers. He is one of the fastest European sprinters in the history of athletics and has won over 30 medals. In 2003 Dwain failed a drug test and it was found that he had taken performance enhancing drugs which were illegal in the sport.
Dwain was banned from athletics and attempted a career in American Football and appeared on the TV series Hell's Kitchen which he soon quit after he was banned. The star was able to return to athletics, however, he had lost himself and his fellow relay team-mates medals after he tested positive for the drugs.
Now he is starring in Celebrity SAS as he wants to test himself and prove to himself that he doesn't give up when the going gets tough. While on the show he spoke about his life after he took the performance-enhancing drugs.
He said: "My whole world fell apart. I started drinking and doing some crap and not facing the reality of what I had done. There came a point where I had to face up and I cried like mad because I realised what I had done."
Dwain added: "When I got the call that I had been suspended from sport, I lost everything. Mum and Dad couldn't help, friends couldn't help... I have to learn to get used to liking things that are uncomfortable for me."
The former athlete now coaches children and wants to be a role model and "example" to them. He said: "Everyone makes mistakes but there is still life after mistakes." Later in the show, Dwain successfully completed a tightrope walk after struggling with long-distance running.
Celebrity SAS: Who Dares Wins is on Channel 4 on Sundays at 9pm or catch up on All4.
