Les Courses du Mont-Terrible

About this event

Les Courses du Mont-Terrible brings together an impressive range of trail options in the Jura mountains, with eight distances from 13km to an epic 107km ultra. The shortest routes climb steadily through forested valleys with around 500-700 metres of ascent, while the longer distances tackle rolling ridges and technical terrain that demand solid preparation. The 107km course, with over 5,000 metres of climbing, ranks among the more challenging ultras in the region. Spring in the Jura means fresh greenery and cool mountain air, and the event's structure allows groups of different abilities to share the same weekend. Strong navigation skills become essential on the longer, more remote sections of the range.
