I'm dreaming of a white Christmas, as the song goes, and for these two Antarctic explorers, that might just be the case.
Louis Rudd and Colin O'Brady are on a race to be the first to succeed in attempting to do a solo, unassisted expedition across the Antarctic continent.
Rudd reached the South Pole on his 41st day while O'Brady peddles ahead and leads by a day and a half as he reached the South Pole after 40 days.
Aaron Teasdale details the experiences and updates from both explorers on National Geographic.
