With her performance in Albi, France, on Sunday, ultrarunner Camille Herron came back strong after a hamstring injury forced her to drop out from Western States in June: She achieved a world best for the most distance covered in 24 hours on her way to winning the International Association of Ultrarunners 24-Hour World Championship. Herron, 37, completed the challenge by running 270.116K (167.842 miles) in a span of 24 hours on a series of 1500-meter loops in and around the Terrain Honneur Stadium. Pending ratification, the ultrarunner’s performance is the record for the most distance covered in a day for women.
