The Sine Qua Non Run is a night race through Paris with a specific purpose: opposing sexual and sexist violence. It begins at Place de la République and provides two distances: a timed 10 km for those aiming for a personal best, and a 6 km option that can be timed or untimed. Participants not in Paris can join via a remote connected option.
The course is a flat urban loop with no elevation change, utilizing the quays and canal paths instead of streets. Runners proceed along the Canal Saint-Martin, around the Bassin de la Villette, head towards Pantin, and return on the opposite bank. The event welcomes a broad range of participants, from novices to seasoned runners, and encourages attendance with friends, family, or individually. Its spirit is both dedicated and communal: the aim is to run at night in Paris while conveying a united message against sexual and sexist violence.
