A land expedition arrives at Concordia in Antarctica. Three expeditions are conducted by the French IPEV polar institute. The ‘Raid’ traverses are used to transport heavy items. The trip takes ten days to complete, climbing over 3000 m from the coast to reach the plateau where Concordia was built.
Pulled by heavy-duty tractors, caravans-on-skis carry 150 tonnes of fuel, food and equipment each time. Once at Concordia, three days are spent unpacking and preparing for the return trip. The trip back to the coast generally takes two days less because it is downhill most of the way.
