Destination X

It's the grand final and the last chance for one player to get their hands on £100,000. After weeks on the road, it all comes down to this, but it's not going to be easy. The players will be put to the test as old clues resurface and older rivalries heat up. A monstrous first challenge will give some players an advantage in the race to the final Destination X, but will it be enough? A nail-biting sprint sees a race around one of Europe's most iconic cities - to where X really does mark the spot. Rob Brydon is the games master and guide for the final leg of this epic journey around Europe, where not everything you see can be believed. And viewers are invited to play along and place their own X on the map at bbc.co.uk/destinationx.
