Sophomore Parker Liautaud, 19, set the world record for the 315-mile trip during the school's winter break, traveling with a companion and a three-person video crew in temperatures as low as minus 72 degrees Fahrenheit from the Ross Ice Shelf to the South Pole, arriving Tuesday, his expedition website said.
The coast-to-pole record was previously held by Norwegian Christian Eide, who completed the journey in 24 days.
The expedition was underwritten by the London-based insurance broker Willis Group, and sought to shed light on climate-related issues, the Yale Daily News reported Wednesday.
The website said Liautaud, who lives in London, will spend several days at the pole, then travel to Punta Arenas, Chile.
It was the first trip to the South Pole for Liautaud, a geology and geophysics major. He has been to the North Pole three times, the newspaper said.
