Season 1

The brothers hit the road, cycling up the east coast of Spain, passing through the palms of Elche, the beaches of Benidorm and Valencia's zoo before arriving at Sagunto, where Hannibal's war against the Romans truly began. On the way, they meet Australian cycling champion Matthew Lloyd and they talk to the elephants - and their keepers.

The Wood brothers continue to cycle north along the east coast of Spain, calling in at Barcelona's famous Camp Nou stadium to watch a football match before visiting the ancient Greek ruins of Ampurias.

From the Roman amphitheatre of Arles, the brothers retrace Hannibal's steps through the south of France to the foothills of the Alps. They recreate Hannibal's historic crossing of the River Rhone before cycling on to the town of Maillane, where the remains of one of Hannibal's elephants were found in the 19th century. They then race up the 2000-metre-high Mont Ventoux before setting off into the Alps.

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.

With the Alps behind them, the brothers cycle through northern Italy from the fertile Valley of Trebbia, where Hannibal's first defeated the Romans on their home turf, to the rolling hills of Tuscany. They continue on through thick marshes before arriving at Cannae, site of the bloodiest battle of ancient history. On the way, the Woods meet a winemaker called Hannibal, attempt to make a pizza in Naples and have a close shave in Trani.

As they come towards the end of their epic journey, the Wood brothers make a sacrifice to the gods at Lake Averno, come face to face with Hannibal in Rome and cross the Mediterranean to Tunisia, once the centre of the Carthaginian Empire, where they visit the site where the fate of an entire civilisation was decided in one final battle. On the way, they meet a Roman centurion and discuss Hannibal's legacy with the souk merchants of Tunis.
