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.
