Night Race "Les Flambeaux"

Course nocturne les flambeaux is a night-time trail event organised by AESN78 in Montfort-l'Amaury, Yvelines, France. The 2026 edition is scheduled for 7 November 2026 and offers two evening races: the Trail XXS of 18 km and a 10 km event. According to the organiser's page the Trail XXS starts at 20:00 and the 10 km at 20:15, providing a distinctive nocturnal running experience across the local landscapes. The event is presented as a focused trail challenge rather than a large expo-style festival.

Participation is for adults only and competitors are required to wear a fluorescent armband and a headlamp, with headlamps explicitly listed as mandatory. The organiser publishes elevation figures (18 km: +450 m D+; 10 km: +300 m D+), and also reports an additional "effort total" metric on the page that appears inconsistent and is noted as ambiguous. Entry fees, prize details and precise GPS coordinates are not published on the organiser page, so competitors should consult the event website for any later updates. The race is aimed at trail runners seeking an atmospheric night challenge in the Île-de-France countryside.
