Le Dernier Survivant – Bois de Boulogne

On July 12, 2026, the Bois de Boulogne–Lac Inférieur race welcomes runners to an exhilarating challenge that combines speed and endurance. The competition begins at 9 AM sharp with a straightforward premise: complete two laps around Lac Inférieur in under 30 minutes—a pace of over 10.8 km/h.
The course, set within the serene Bois de Boulogne forest, offers runners picturesque views as they navigate its winding paths and cross the finish line at the base of Lac Inférieur. The race continues until no more participants can sustain the required speed for two consecutive laps in the allotted time frame. A lively hub near a free parking lot serves as the event's heart, providing essential amenities to all competitors.
At each lap, runners have access to water from a fountain and various snacks like pain d'épice, cereal bars, coffee, and biscuits. Competitors are encouraged to bring their own supplies for personal comfort during breaks or overnight stays if needed. A supportive community atmosphere ensures that participants feel welcome and well-supported throughout the event.
Registration is available up until 15 minutes before the race start time at 8:45 AM on site. All runners must wear their bib numbers prominently displayed to remain eligible; failure to do so will result in disqualification from the competition.
The race employs a real-time timing system, meticulously recording each lap completion and displaying results immediately for transparency.
This private event emphasizes camaraderie over strict rules. Runners are responsible for their own safety but can expect an inclusive environment that fosters mutual respect among competitors. Breaks along the route are permitted as long as participants maintain compliance with the 30-minute rule between laps.
Participants who exceed this initial timeframe may continue to compete, though only those completing both loops within the deadline will advance to subsequent heats. Those unable to meet these conditions after their first lap can still complete it for partial recognition in the final standings but must wait until the next designated start time before resuming full participation.
The Bois de Boulogne–Lac Inférieur race promises an unforgettable experience, blending natural beauty with competitive spirit and community support.
