Les Folies du Vignoble is a one-day outdoor sports event in Vallet, organized by Vélo sport valletais and Iron Team 44, the local triathlon club. It features five competitions at the same location, with the first starting at 9 a.m. The program combines trail running, gravel cycling, mountain biking, and orienteering, designed for club athletes, families, and groups of friends, not just one specific type of competitor.
The gravel ride, a recent addition, offers three loop choices of 50, 100, or 150 km along the Loire, with two returns to the partner village before the finish. Trail runners select either 12 or 28 km on routes near the border of Loire-Atlantique and Maine-et-Loire. Mountain bikers face a six-hour challenge on an 8 km loop, competing solo or in teams of up to four. Adults and children can participate in a family orienteering course together. The event has faced disruptions recently, including cancellations due to Covid and a heatwave, prompting organizers to schedule it earlier in the season for a greater likelihood of proceeding.
