Iain takes on the last 52 miles of the iconic trip joined by familiar faces along the way. A week into adventure, he and his River City co-star Lesley Hart start with an easy six-mile walk from Crianlarich to Tyndrum. On his journey, an astonished Iain enters the mist-swirling valley of Glencoe, while a rained-off climb sees him reunited with Small Faces actor Stephen Duffy. With some challenges, a relieved Iain makes it across the Devil's Staircase while he enjoys a day in the small town of Kinlochleven. Exhausted, he finally descends into Fort William before ascending to Scotland's ceiling by climbing Ben Nevis.
