UTMB, spanning three international borders and encircling Europe’s highest peak, is globally acknowledged as one of the most demanding ultra-marathons, characterized by both a festive ambiance and a staggering elevation gain surpassing Mount Everest.

Her summer of 2023 not only marked a triple crown by conquering the Western States 100, Hardrock 100, and UTMB in a single season but also solidified her status as an unparalleled force in ultra-running.

A decade ago, at Run Rabbit Run in Steamboat Springs, Colorado, Dauwalter faced the humbling experience of a did-not-finish (DNF). Alone and disheartened, she made a pivotal choice to transform into someone capable of completing 100 miles.

Dauwalter’s triumphs extend beyond UTMB; her victories in the Moab 240 and other major races challenge conventional assumptions about gender differences in ultra-endurance sports. The ongoing debate on whether longer race distances neutralize gender gaps has gained traction, prompting research and discussions within the running community.
