Runners begin at the Château de Boutenac, the home of AOC Corbières winegrowers, then enter the Corbières hills. Nature Trail Boutenac is a spring trail-running event held in Boutenac, a wine village in France's Aude region. The available events include a very technical 20 km race, La Ligne de Crête des Corbières, featuring significant elevation gain; a 10 km trail named Le Trail de Saint Siméon; a 10 km walk; and short, free races for children called La Pitchounette. This event accommodates experienced trail runners, newer participants, walkers, and families, not just a single type of athlete.
The courses traverse rolling hills, steep ridges, vineyards, and rougher paths requiring careful footing. Boutenac is located in the origin area of the AOC Corbières appellation, and the village contributes local character through its wine-growing streets and Romanesque church. The surrounding scrubland hosts Mediterranean flora like thyme and rosemary, and participants might see birds of prey or wild boar. Following the races, the event emphasizes local food and wine, offering AOC Corbières tastings, a meal featuring wild boar stew, charcuterie, and cake, followed by a dance.
