Courtney Dauwalter is widely considered the greatest ultramarathon runner of the modern era, celebrated for her cheerful demeanor, legendary pain tolerance, and historic habit of beating entire fields of male and female competitors alike. Born in Hopkins, Minnesota, in 1985, she was a four-time state champion in Nordic skiing before attending the University of Denver on a skiing scholarship and later earning a Master’s degree in teaching. After working for several years as a middle and high school biology and chemistry teacher, she turned professional in 2017 and began completely rewriting the limits of human endurance. Dauwalter achieved ultimate legendary status during her historic 2023 season, becoming the first person ever to win ultrarunning’s prestigious "Triple Crown" in a single summer: the Western States 100, the Hardrock 100, and the Ultra-Trail du Mont-Blanc (UTMB), shattering course records along the way. Her dominance spans diverse terrains and astronomical distances, famously winning the 2017 Moab 240-mile race outright by beating the second-place male finisher by more than 10 hours.
