Advancing Scientific Understanding of Women Ultrarunners With the Women’s Health Programme

Why It Matters

Understanding female‑specific physiology will boost athlete safety, expand the market for women’s endurance products, and attract more sponsors to a rapidly growing segment.

Key Takeaways

• Female participation rose to 30.5% in 2025.
• Program partners UTMB and Ultra Sports Science.
• Research focuses on menstrual, hormonal, pregnancy, gut health.
• 2026 UTMB acts as open‑air laboratory.
• Elite athletes contribute data and advocacy.

Pulse Analysis

The surge in women’s ultrarunning—up from 16% of participants in 2007 to over 30% today—has outpaced scientific understanding of female‑specific physiological demands. Traditional endurance research has largely treated women as scaled‑down men, leaving gaps in knowledge about menstrual cycles, hormonal fluctuations, and gastrointestinal challenges that uniquely affect long‑distance performance. This data void hampers coaches, product developers, and medical professionals seeking evidence‑based strategies for female athletes, creating a market opportunity for targeted solutions.

The Women’s Health Programme tackles this shortfall by turning the 2026 UTMB into a living laboratory. Ultra Sports Science will deploy wearable sensors, blood panels, and detailed questionnaires to a diverse cohort of elite and amateur runners, while a convened panel of physicians, exercise physiologists, and nutrition scientists interprets the results. The inclusion of high‑profile athletes—Camille Bruyas, Blandine L’Hirondel, and Marion Delespierre—provides both credibility and real‑world insight. A public congress during the UTMB festival will disseminate preliminary findings on mental health, gynecological issues, and digestive health, fostering cross‑cultural analysis and immediate knowledge transfer.

For the broader endurance industry, the program promises actionable intelligence that can drive product innovation, from hormone‑responsive nutrition to gender‑specific hydration systems. Coaches will gain evidence‑based protocols to tailor training cycles around menstrual phases, while sponsors can align brands with a scientifically grounded narrative of female empowerment. Ultimately, the initiative could set a new standard for data‑driven athlete support, encouraging more women to pursue ultrarunning safely and sustainably, and expanding the commercial ecosystem that serves them.
