Lamas'trail is a trail-running and walking event in Lamastre, Ardèche, featuring short, hilly routes within the local terrain. Typically held in September and organized by Association La Trace, the individual trail distances are approximately 7 km, 14 or 15 km, 21 km, and occasionally a longer 29.3 km option. The 7 km trail involves a 287-meter climb, and the 21 km route ascends about 1,000 meters, demanding significant uphill effort even on the shorter courses.
The event accommodates both runners and walkers. Pedestrian hikes are offered over 7 km and 14 km. Discovery trail options include the 7 km and the 14 km “Trail le panoramique.” Short-trail races cover the 21 km and 29.3 km routes. The longest course totals approximately 1,412 meters of elevation gain over 29.26 km, emphasizing climbing strength and pacing over flat speed. Recent participation was just under 300 people, contributing to a local Ardèche race day atmosphere rather than a large city event.
