The Adventure Show is in Torridon for the Celtman Extreme Scottish Triathlon, which starts with a three kilometre open water swim that's followed by over 200 kilometres of biking. The finale is a 42 kilometre run, which includes anascent of one of Scotland's Munros. It's been described as one of the toughest days of your life and for most just finishing is a major achievement.

In this programme, The Adventure Show is in the imposing landscape of Glencoe, for what must be one of the most dramatic marathon courses anywhere in the UK. The scenery may be inspiring, but this is a tough race with over 1,600 metres of ascent including 500 metres over the aptly named Devil's Staircase.
