A British schoolboy is today expected to become the youngest person to trek to the South Pole.
Lewis Clarke, 16, should arrive at the Amundsen-Scott South Pole Station at around 3pm (GMT) after completing the gruelling 700-mile journey from the Antarctic coast.
He said earlier this week: "M y body has had enough. I am forcing it to go on."
Lewis, from Bristol, set off on December 2 and has spent the past 46 days travelling on skis in temperatures as low as minus 40C and winds of up to 60 mph.
He is two years younger than the current world record holder, Canadian Sarah McNair-Landry, who completed the trek in 2005.
The Briton, accompanied by guide Carl Alvey, has skied an average of eight hours and 18 miles a day.
Lewis, who is raising money for youth charity The Prince's Trust, is pulling his own supplies, although he has received three food drops.
