Ann Trason
Ann Trason won the Western States 100-Mile Endurance Run a record 14 times between 1989 and 2003, establishing a level of sustained dominance at ultrarunning's most historically significant race that remained the sport's benchmark for consistency for decades afterward. Her numerous world records across multiple ultra distances during the 1990s, at a time when women's participation in ultrarunning was still comparatively rare, helped establish the sport's competitive legitimacy for women and inspired a generation of subsequent female ultrarunners. Trason's 1995 overall victory, beating the entire men's field outright at a 100km race, became one of the earliest and most significant examples of a female ultrarunner outperforming the top men's competitors directly, a result that predated similar breakthrough performances by decades. Her combination of her record 14 Western States victories and her pioneering role establishing women's ultrarunning legitimacy has made Trason widely regarded as one of the most foundational figures in the sport's history.
VS
Courtney Dauwalter
Courtney Dauwalter has won the sport's three most prestigious 100-mile races — Western States, the Ultra-Trail du Mont-Blanc, and the Hardrock 100 — all in the same calendar year on multiple occasions, an achievement widely regarded as one of the most dominant single-season stretches in ultrarunning history. Her victory at the 2017 Moab 240, in which she finished first overall by more than ten hours ahead of the second-place male finisher, became one of the sport's most widely discussed results and helped establish her broader reputation for a competitive toughness that transcended typical gender-based race performance gaps. Dauwalter's sustained dominance across wildly varying terrain and distances, from technical mountain courses to flatter, faster desert races, reflected an unusually complete skill set relative to ultrarunners who typically specialize in one specific type of course. Her combination of her unprecedented same-season sweep of the sport's three biggest 100-mile races and her genre-defining overall victories against male competitors has made Dauwalter widely regarded as the greatest ultrarunner competing today.
