In the final challenge of the series, there are 10 contestants, four final places on offer and one last chance to gather vital points. For challenge number five, our intrepid contestants headed north – as far as the Local Government Association (LGA) boundaries will allow.

At 9am sharp the contestants met outside Cumbria CC's purpose-built and impressively high-tech HQ for a whistle-stop tour of Carlisle's historic city centre, including hidden Freemason marks and interesting medieval tales.
