Stephanie Case becomes first woman to complete 100-mile run in Antarctica

Human rights lawyer Stephanie Case has become the first woman to run 100 miles in Antarctica. She finished the race 29 minutes after Chinese athlete Yusheng Ni, who set a new world record by improving his previous time from last year by more than five and a half hours.

Case had aimed to break the world record during the event, though she acknowledged that competing against Ni, who has finished over 500 ultramarathons, represented a "formidable challenge". She said, "There were parts where I was 60 seconds behind him or I was sometimes just 200 metres behind him. It was a real race. But whenever he saw me getting close, he would look behind and he would just take off. I think we really pushed each other to get our best performances. I feel super proud of what I was able to do."

Last year, Case gained viral attention for breastfeeding her baby daughter Pepper while winning an ultramarathon in Snowdonia. Although the reaction was mostly supportive, she noted that some negative comments motivated her to attempt this feat to prove "motherhood is not the finish line". She described completing the run on what has historically been called the "womanless continent" as a fitting accomplishment.

"I know that when I'm going out and doing the things that make me feel happy and whole, it makes me a better mum and I can come home and and show my daughter all the things that she might want to do and all the things that are possible for women," Case said. She added, "I felt like the best way to clap back at anyone who thought that I should be at home with my baby was to go to the most extreme place on Earth and try to get the record."
