Ultra-Trail des Montagnes du Jura is a mountain race in the Jura Mountains, linking France and Switzerland.
The courses start at different points throughout the range and are divided by distance before finishing in Métabief.
From the shortest Chamois to the long-distance solo races and the relay,
where teams divide the course between runners, each event explores the same mountains over a different distance.
The children’s race takes place as a loop course in Métabief.
The headline 175 km race starts in Lancrans.
It is a cross-border course along technically demanding narrow mountain trails,
passing through several French administrative areas before entering Switzerland, with an official elevation gain of 7,000 m.
The long journey to Métabief via Les Rousses, Mouthe, and Jougne reflects the event’s character: running through the Jura one section at a time.
A relay event on the same course is also available.
The Franco-Suisse is a 105 km course starting in Les Rousses and crossing the border while climbing mountain peaks.
The 75 km Renard also starts in Les Rousses, but it showcases the Jura’s terrain in a condensed form, moving between gorges, ridges, summits, and forests.
The Swiss section is included in the 300 km relay and the 175 km and 105 km races, while the other events remain on the French side.
The 300 km Jurassienne relay starts in Hauteville-Lompnes and crosses the range over a long route.
The character of each event is defined not simply by its distance, but by its starting area,
whether it crosses the border, and how it links the terrain together.
