Running While Female: Sine Qua Non and the Push for Safer Streets

Paris – The simple act of going for a run shouldn’t require a risk assessment, yet for many women, that’s precisely what it entails. From unwanted attention to outright harassment and, tragically, violence, female runners face unique safety challenges that are prompting a growing movement for change. At the forefront of this effort is Sine Qua Non, a French association working to reclaim public spaces and empower women through sport. Their work comes as concerns about safety continue to grow, with twelve women having been killed in France since 2005 while jogging, the most recent being Agathe Hilairet in April 2025.

A History of Harassment

The issue isn’t new. A 2017 Runner’s World survey revealed that 43% of female runners had experienced some form of harassment, leading 27% to abandon the sport altogether for indoor activities. The spectrum of harassment is broad, ranging from verbal abuse to physical intimidation. As Tiphaine Poulain, co-founder of Sine Qua Non, explained, the experiences shared with her organization are deeply unsettling. “It can range from a sexual proposition to being followed, or an insult to a hand on the buttocks,” Poulain said. “But Notice also whistles, remarks like vas-y cours plus vite avec ton gros cul. All of this leads to a feeling of insecurity that hasn’t necessarily been experienced but is clearly perceived.”

Sine Qua Non: Reclaiming Space Through Sport

Founded in 2018 by Mathilde Castres and Tiphaine Poulain, Sine Qua Non (meaning “without which, not”) tackles the problem head-on. The organization’s philosophy centers on the idea that sport can be a powerful tool for empowerment and a catalyst for social change. They believe that by increasing women’s confidence and visibility in public spaces, they can challenge societal norms and reduce the incidence of harassment and violence.

Sine Qua Non’s initiatives are diverse and impactful. The Sine Qua Non Run, an annual 5 or 10km race, will hold its eighth edition on March 28, 2026, starting in Place de la République in Paris. A digital version, partnering with Strava, will allow participation from anywhere in the world, under the hashtag #RunForEquality. But the organization’s work extends far beyond a single event.

Taking Back the Streets

A key component of Sine Qua Non’s strategy involves organizing running and training sessions in areas often considered “unfrequented” by women. This deliberate act of reclaiming space is designed to assert women’s right to exercise where, when, and how they choose. These sessions aren’t just about fitness; they’re about building community and fostering a sense of solidarity.

The Sine Qua Non Squads represent another innovative approach. These are community-based groups of female football (soccer) players who utilize urban spaces as their playing fields. By playing in mixed-gender teams, they aim to promote a more egalitarian approach to urban sports and serve as role models for young girls. The goal is to encourage greater female participation in traditionally male-dominated spaces like city sports courts.

Boxing and Empowerment

Sine Qua Non also offers introductory boxing classes, utilizing urban furniture and street workout spaces. This combination of physical training and reclaiming public areas is intended to build confidence, release mental stress, and demonstrate that no space is off-limits for women. The organization recognizes that feeling safe isn’t just about physical strength, but also about mental resilience and a sense of self-assurance.

The Need for Male Allies

While Sine Qua Non’s efforts are focused on empowering women, the organization emphasizes the crucial role of men as allies. As the organization’s work has evolved, it’s become clear that lasting change requires a collective effort. Creating a safer environment for female runners isn’t solely a women’s issue; it’s a societal one that demands the active participation of men.

Looking Ahead

Sine Qua Non’s work is a testament to the power of sport as a vehicle for social change. By addressing the safety concerns that prevent women from fully enjoying the benefits of running and other outdoor activities, the organization is not only empowering individuals but also challenging deeply ingrained societal norms. The next major event on the calendar is the Sine Qua Non Run on March 28, 2026, in Paris, and the ongoing expansion of the Sine Qua Non Squads and training programs.

The conversation around women’s safety in sports is ongoing, and Sine Qua Non is committed to continuing this vital work. What are your thoughts on creating safer spaces for female athletes? Share your experiences and ideas in the comments below.
