Overview: Biomass trucker Craig Garside is undaunted at taking on a 172-mile journey delivering a mucky load of loose peat. For someone as experienced as Craig it should be a piece of cake, but will an unexpected wall of freezing fog around the Pennines stop him in his tracks? Multi-drop maestro Dave Pickerill faces his worst nightmare. He has two days to make ten deliveries on his least favourite route, the outskirts of London. Will he be able to beat the London traffic and complete his marathon? Mild-mannered Andy Thornton prides himself on being on time, every time. For this long-haul trucker, travelling the length and breadth of the country is all in a day’s work. A 278-mile trek from Middlesbrough to Magor in Monmouthshire should be no problem, but a nasty surprise awaits when a motorway accident forces Andy to take a huge cross-country detour.
