Longest polar ultramarathon world record broken in Antarctica

Australian ultrarunner Donna Urquhart battled sub-zero temperatures, ferocious winds and logistical issues as she broke the world record for the longest-ever run in a polar region, pending ratification. Urquhart, who is a pain researcher by day, covered a total of 871 miles over the course of 28 days in Antarctica from December 15, 2023 to January 11, 2024. #antarctica #ultramarathon #southpole #cnn #news
