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.
VS
Scott Jurek
Scott Jurek won the grueling Western States 100-Mile Endurance Run seven consecutive times from 1999 to 2005, a run of sustained dominance in one of ultrarunning's oldest and most prestigious races that remains unmatched in the event's history. His subsequent 2015 supported speed record for completing the entire 2,189-mile Appalachian Trail, finishing in just over 46 days, demonstrated a rare combination of ultra-distance racing speed and multi-week sustained endurance across a genuinely different competitive format than his trail-race career had been built on. Jurek's plant-based diet, unusual among elite endurance athletes at the time of his early career peak, and his subsequent bestselling memoir "Eat and Run" helped raise ultrarunning's broader public visibility well beyond its traditionally small, dedicated community of participants. His combination of his record seven-peat at Western States and his subsequent Appalachian Trail speed record has made Jurek widely regarded as the most publicly influential ultrarunner in the sport's modern history.
