This year, the 6th edition of the Ultra Trail des Montagnes du Jura broke all records, both in terms of number of runners and weather conditions.

Despite rain, wind, cold, hail, and even snow more than 10,000 adult and junior runners pushed their limits in the heart of the Jura Mountains and celebrated this exceptional adventure together.

A huge thank you to everyone who took part in this fantastic edition, with a special mention to our 1,000 volunteers who made this major sporting event possible. Thank you for your commitment, your energy, your smiles, and for supporting the runners throughout the weekend!

Onwards to next year! See you on 1, 2, 3 and 4 October 2026!
