Camille Herron ran 270.116km in 24 hours in Albi, France, on Sunday to win the International Association of Ultrarunners 24-Hour World Championship and set the women’s world record. Herron, 37, broke her own record of 262km, which she set last year. The American took the lead on the first lap at the 1,500m track and never relinquished her position. In fact, she almost caught the men’s winner at one point. Herron dropped out of the Western States 100 in June, citing hamstring issues, but she has a host of accolades to her name, including a 2017 win at the Comrades Marathon in 2017. Bizarrely, she also holds the marathon record for running in a superhero costume. Not many elites can say they covered 167 miles in a week, a lot of people don’t hit that for a month and @runcamille just hit that in 24hrs bettering her own world best!!!! 167.8 miles in one full day, let that sink in I’m exhausted just thinking about it! @iRunFar @usatf — Maria Michta (@MariaMichta) October 27, 2019 Herron has been vocal about the need to bring more stringent drug testing to ultrarunning, calling on the likes of the International Trail Running Association to conduct more tests.
