Women Redefining Endurance: New Zealand Runner Breaks Records in Ultra Sports

Shifting the Paradigm in Endurance Sports

Sophie Woods is rewriting the narrative of endurance sports. Recently, this New Zealand runner astonished the athletic community by completing the Via Alpina—a 2,000-kilometer route from Trieste to Monaco—in an astonishingly fast 29 days. Not only did she claim the title of the fastest overall runner on this challenging track, but she also outpaced the previous male record by more than a week. Such achievements highlight a significant trend: women are increasingly breaking through barriers once held exclusively by men in extreme sports. This isn’t an isolated incident. Just consider Rachel Entrekin, who, in 2026, conquered the Cocodona 250–a grueling 400-kilometer race in the U.S.—setting a new overall course record. Then there’s Tara Dower, who just a year earlier, ran the Long Trail in Vermont, completing approximately 440 kilometers in just over three days, smashing the previous men’s record by a notable two hours and forty minutes. These accomplishments are telling, indicating a shift in performance dynamics across endurance sports.

Interestingly, a study by RunRepeat and the International Association of Ultrarunners analyzed over five million results from more than 15,000 ultramarathons. It revealed that as race distances increase, the performance gap between genders closes significantly. While men traditionally finished 11.1% faster in shorter events, the margin shrank to a mere 0.25% at the 100-mile mark. In races exceeding 195 miles, women were observed to outperform men by an average of 0.6%. This suggests that longer distances allow women to leverage their endurance strengths more effectively than shorter sprints.

The Physiological Advantage

So, what’s behind this trend? Several physiological factors could be influencing performance outcomes. Women generally have a higher percentage of Type I muscle fibers, which are known for fatigue resistance, and they can rely more on fat as a fuel source during endurance activities. This could mean that the strength and oxygen capacity advantages that men possess may be less critical in ultra-endurance races. Woods herself notes that this endurance might be partly due to psychological factors too. She believes women excel at problem-solving and can set aside egos during long, grueling events. "We control what we can and then throw it all into chaos," she remarked, underscoring the complex interplay of planning and adaptability that ultramarathons demand.

Challenges and Sacrifices

The toll of such extreme sports is not insignificant. For Woods, the grueling experience included sleeping as little as 90 minutes per night, often collapsing on the side of the trail. "The sleep deprivation was one of the hardest parts," she recounted. Managing energy levels presented another hurdle, with her team estimating a caloric intake of between 6,000 and 7,000 calories daily. Her meals varied from burritos to fast food, consumed on the fly as she navigated through demanding terrains like the Dolomites. Despite the physical and mental exhaustion, Woods emphasizes that the sheer act of trying is what truly matters. "The bravest thing to do is to try; it doesn't matter what happens in the end," she said. This mentality not only exemplifies her character but also challenges the traditional stereotypes of female endurance athletes.

The Need for More Research

Yet, as she revels in her accomplishments, Woods raises a critical issue: the need for increased research in women's sports physiology. Women's bodies have been neglected in scientific studies for too long, often overshadowed by male-centric research. "We have just been left behind for decades," she points out, advocating for more focus on female athletes to unlock their potential fully. The breaking of men's records by women is significant, but it highlights just one facet of a broader conversation. It doesn’t imply that women are innately superior in endurance sports; rather, it reveals that in long-distance events, the playing field can become more level. Woods embodies this spirit of determination, reminding us that courage is about facing the unknown and pushing boundaries in sports and society alike.
