Before heading to the Canadian Arctic and the Cross Canada Expedition, Ben and Natalia cycled 3,600km from São Paulo to Santiago with the Daylong Challenge. They headed south from Brazil through Uruguay and across the bay to Buenos Aires in Argentina. From there they cycled across Argentina and the Andes into Chile, with a journey that was to last 40 days and, as opposed to the frozen climes of the Arctic, offered often stifling temperatures and intense sun.
