Race Across the World
8pm, BBC One
Time to strap on the big rucksacks again, as the BBC’s globetrotting hit returns for a sixth series. The starting gun is in Sicily, where five duos psych themselves up for a 12,000km yomp through Europe and Asia without access to flights, phones or much in the way of funds. Their ultimate goal? Northern Mongolia (and a £20,000 prize if they are first). Graeme Virtue
