Ultra Monplaisir is a trail running series in Saint-Priest, Rhône, France. The event provides four distances: 10 km, 25 km, 45 km, and 85 km, accommodating both short trail runs and an ultra-distance option.
The longer races begin in the morning: the 85 km at 08:00, the 45 km at 09:00, and the 25 km at 10:00. ULTRA 93 organizes the event. The range of distances is the key detail: runners can choose from a 10 km trail to an 85 km course.
