Ultra trail races

The UTTJ is more than just an ultra trail race with a vertical kilometre. It is an invitation to (re)discover an authentic and sometimes harsh corner of nature at its most beautiful. The UTTJ is all about warmth, friendship and hospitality, bringing regular participants together year after year and encouraging new ones to do the same.

The itinerary changes each year, giving runners the chance to explore ridges, valleys and gorges and discover all the wonders of the Upper Jura Regional Nature Park. The UTTJ is open to all, from novices to experienced trail runners, participating solo or in a relay team!

Participants can also sign up for the bivouacking option:

• 2 nights including breakfasts and the Saturday evening meal €50
• 1 night (Saturday) with evening meal and breakfast €25
