A 16-year-old boy from Bristol has set a new record by becoming the youngest person ever to trek to the South Pole.
Lewis Clarke has spent almost 50 days at temperatures as low as -50C (-58F) and winds of up to 120 mph (193 kmh).
He arrived at the Amundsen-Scott South Pole Station in the last hour after completing the gruelling 702-mile journey from the Antarctic coast.
He will now be submitting evidence to Guinness World Records so that his claim can be officially verified.
Speaking earlier in the day when his son was still about 10 miles from the Pole, his father Steven said Saturday's weather had been the "worst yet".
The QEH Bristol (Queen Elizabeth Hospital) pupil is hoping to have broken the record for the same coast-to-pole route taken by Sarah McNair Landry from Canada in 2005, when she was aged 18.
The challenge began on 2 December, two weeks after his 16th birthday, and brings an end to an expedition which has seen Lewis ski for an average of eight hours a day
He has pulled his supplies behind him on a sledge with help provided by the experienced polar guide Carl Alvey.
Problems encountered along the way have included blisters, coughs caused by being at high altitudes, and a broken ski.
His record-breaking feat has raised more than £2,000 for The Prince's Trust.
