On Hannibal's Trail - Over the Alps

History and travel series in which three Australian brothers - Danny, Ben and Sam Wood - set out cycling on the trail of Hannibal, the Carthaginian warrior who marched from Spain to Rome at the head of an invading army accompanied by elephants. The brothers take on the most challenging leg of their trek - crossing the Alps. Historians disagree about which route Hannibal took across the mountains, and the Woods split up and each cycle a different path. They brave snow, altitude and sheer exhaustion as they carry their bikes across some of the highest peaks in the Alps. Finally, they meet up in northern Italy, ready to take on Rome.
