The races traverse the trails surrounding Montgailhard, with challenging and varied terrain. A notable local landmark is the Pech, also known as the Pain de Sucre or the Pic, a climb offering a 360-degree panorama from its summit. Sport Nature Montgailhard originated from friends gathering to run, decompress, and socialize; it has since grown to over 100 members, with weekday group runs, a Sunday long run, and a cycling section. This community spirit extends to race day, with organizers focused on both the race and the camaraderie after the finish.
