Explorer Sir Ranulph Fiennes has announced that he's to lead a record-breaking trek across Antarctic. The 68 year-old who lives on Exmoor plans to head the first team to walk the continent during winter. The six-month expedition is due to begin next March.
Fiennes is described by the Guinness Book of Records as the world's greatest living explorer. His achievements include becoming the oldest person to climb Everest at the age of 65.
Seven years ago he recovered from a heart attack and a double by-pass operation. Fiennes will start his latest challenge on the Pacific ice shelf where Captain Scott died a hundred years ago.
