There is nothing about this programme that is believable.
There is a caveat at the beginning that CCTV, ANPR camera access and mobile phone monitoring have been 'recreated'. So in other words all the 'hits' the hunters have on their system, all the clues they get from listening in to the hunteds' calls, all the 'pings' from mobile masts etc etc are given to them by the producers - as if[i they could see all CCTV in the country and so on.
All those on the run have a cameraperson embedded with them, but where do they sleep? The two young guys who made it to the end spent most of their days on the run camping, so where did the cameraperson sleep, in a tent nearby? And when those two split up, they miraculously had a camera each following them! Makes someone pretty damn obvious, no?
If those hunted did not use a mobile phone or the internet and did not contact their family or friends (funny how the hunters always manage to'guess' who those on the run are going to contact!), it would be easy to stay undetected - but not much of a programme.
And of course at the end there is [i]always] the breathless dash to the waiting boat/helicopter, with the hunters just failing to catch them....
