Hillary Allen

Hillary Allen is an American professional ultrarunner and endurance athlete who began trail running while studying for her PhD in science and soon became an accomplished high-altitude trail runner. In 2017, when she was ranked among the top runners in the world, she fell 150 feet off a ridge at the Hamperokken Skyrace in Tromso, Norway, breaking both arms, two vertebrae, several ribs and bones in her feet. Nicknamed Hillygoat, she spent a year recovering before returning at the Broken Arrow Vertical kilometer race in 2018, and two years after the accident she completed the same Norwegian course. She also races gravel events, qualified for Team USA at the 2025 World Mountain Running Championships Uphill Race, and wrote the book Out and Back.
