The show features the toughest men in Britain tackling some of the hardest military courses in the world; these require intense physical and mental endurance.
The show offered to test the real techniques used by Special Forces from around the world; only the fittest, strongest, bravest and toughest were eligible.
Sophie mistakenly thought that the show was the right fit for her, and was very disappointed to receive a reply suggesting that being tough wasn't enough; she also needed to be a man.
"The idea is we want to keep it as 'real' as possible and in the special forces we are featuring, women are not currently eligible, unfortunately," stated the response.
Sophie therefore failed to achieve her mission to encourage people, and especially women, to live fearlessly, live without limits and believe in themselves, as she put it in her blog.
