CNN said the group trekked more than 200 miles across the frozen continent.
The organization tweeted Friday: "At 13:25 Expedition HQ received a call to confirm that the @VirginMoney #SouthPole2013 party arrived at the South Pole at 12:48 GMT."
"We started out this morning and visibility was very, very bad," team coach Alex Skarsgard said in his last expedition diary entry before the team reached its goal.
"We couldn't see much at all but then around 3 o'clock in the afternoon it cleared up and we could see the South Pole station," he said. "It is the first time in a month that we have seen a structure and the whole team just stopped and stared at it for about 5 minutes -- it was a very surreal experience. [...] To literally see the end of this adventure was very emotional for all of us. ... People are very tired, physically and mentally as well. It has been a couple of very intense weeks but spirits are high, most people are excited about getting to the pole."
