The expedition began on the edge of the Ross Ice Shelf on 20 November and involved climbing the Transantarctic Mountains, via the Leverett Glacier, to reach the polar plateau.
They took in new supplies at the South Pole before they made their way to Hercules Inlet, skiing 373 miles across uneven ground, and spent Christmas Day on the ice before arriving at their final re-supply point at the base of the Thiel Mountains.
From there they descended to the Hercules Inlet to the finish line.
