The 86d+ Trail is a Friday-night off-road race held in Chasseneuil-du-Poitou, located in the Vienne department of Nouvelle-Aquitaine, France. Participants begin at 8:06 PM from the Parc d'Activites Sportives Piece des Cards, a detail that adds to the event's memorability. The race offers two trail distances: 10.6 km and 18.6 km. The next edition is scheduled for early April.
The course guides runners onto local trails after sunset. Organizers note that the terrain includes sufficient climbing and rough ground to challenge participants' calves. While intended for trail runners, the two distance options accommodate various skill levels. Team Tri 86 is the organizing body, and the event uses the slogan "Much more than a number!" along with the hashtag #86d+. Having recently completed its third edition, it maintains the feel of a community night-trail event rather than a large-scale, established race.
