An Oregon man has become the first person to traverse Antarctica alone without any assistance.
Colin O’Brady, of Portland, finished the 932-mile (1,500-kilometer) journey across the continent in 54 days, lugging his supplies on a sled as he skied in bone-chilling temperatures.
O’Brady documented the entire journey on his Instagram page , and says it came to an end Wednesday after he covered the last 77 miles (124 kilometers) in one big push to the finish line.
His wife, Jenna Besaw, says she and O’Brady’s family stayed up all night watching his progress using an online tracker and that he called as soon as he finished to tell them “I did it!”
Though others have traversed Antarctica, they either had assistance with reinforced supplies or kites that helped propel them forward.
