The Transglobe Expedition was the first expedition to make a circumpolar navigation, traveling the world "vertically" traversing both of the poles using only surface transport. Starting in 1979 from Greenwich in the United Kingdom, adventurers Sir Ranulph Fiennes and Charles R. Burton went south, arriving at the South Pole on 17 December 1980. Over the next 14 months, they went north again, reaching the North Pole on 11 April 1982. Travelling south once more, they arrived again in Greenwich on 29 August 1982. Oliver Shepard took part in the Antarctic leg of the expedition.
