Here are the rules:
They have a 30 minute head start. They can take whatever they can carry including a tent etc. They have 28 days to get to the designated end location. They must not break the law. During active hours of hunting they must keep on the move and change location regularly – no hiding in the sewer for the entire time. They must attempt to throw the hunters off their scent – and do their best to decoy them. They need to make use of a support network and they must make contact with family and friends. They have £250 in a bank account, only accessible in small amounts via an ATM. I believe they must get the money out regardless of whether its needed as a rule. They must take with them a cameraman.
We are never told the rules on the show (only on the website). This means the players are made to look stupid when choosing not to hide in an abandoned house for the duration, as that would be trespassing. They are required to call home which gives away their location, but it is edited to look as though they are being stupid and doing it out of impulse.
Also, the law rule is ignored as hitchhiking is illegal in this country but they happily ignore that.
Its an interesting show, but the rules need better clarification and explaining to the viewers so we understand the game more, if we are truly to do as they request and ask ourselves what would you do?
