Women’s Edge in Ultra-Endurance Running

Emerging Understanding of Female Resilience
Commentators and experts are examining why women often excel in ultra-marathon events that last multiple days and involve extreme terrain, sleep loss, and unpredictable conditions. The discussion blends physiological speculation with observations of mental toughness and community dynamics among elite female ultra-runners.
Expert Perspectives
Tim Jones, a key figure in Eliud Kipchoge’s 2019 sub-two-hour marathon project, notes that scientific research on ultra-distance performance lags behind studies of shorter races. Dr Richard Burden, co-lead of female athlete health and performance at the UK Sports Institute, echoes this gap, stressing that physiological adaptations favoring women in ultra events remain poorly documented.
Sophie Woods, a New Zealand ultra-runner who set a record on the Via Alpina, attributes her success to preparation, mental strength, and the ability to persevere when faced with setbacks such as wildfires and swarms of horseflies. Yngvild Kaspersen, the first woman to win the Ultra-Trail Mont Blanc CCC race twice, links her victories to a deliberate “mental game” cultivated during training and highlights the strong camaraderie within the female ultra-running community.
Sports dietitian Renee McGregor, who also competes in ultra-runs, argues that the female body’s fluctuating hormonal system—experienced from puberty onward—constitutes an inherent form of endurance. She points to research suggesting women tend to adopt more disciplined and even pacing strategies, which she describes as a “brain bank” advantage. McGregor adds that life experiences such as pregnancy, sleep deprivation, and fertility treatment may reinforce problem-solving skills that translate to race resilience.
Mental and Community Factors
The athletes and experts stress that ultra-running demands continuous movement despite discomfort, and that women’s ability to adapt and maintain momentum is reinforced by a supportive network of peers who motivate and push each other during competitions.
Physiological Considerations
Current evidence on gender-specific physiological benefits in ultra-endurance is limited. Researchers call for more targeted studies to confirm whether hormonal fluctuations and other female-specific adaptations provide measurable advantages over male counterparts.
Implications for the Sport
Understanding the blend of mental resilience, community support, and potential physiological factors could shape training programs, encourage greater investment in gender-focused research, and highlight the growing prominence of women in the ultra-running arena.
