La Transjurassienne evolves: a new chapter begins in 2027
A legendary event in French cross-country skiing, La Transjurassienne has always evolved alongside its territory. Facing the impacts of climate change and snow conditions that have become more unpredictable over the years, we are choosing to reinvent the race to safeguard its future.
👉 Starting in 2027, La Transjurassienne will feature a benchmark 50 km course between Lamoura and Les Rousses.
Through this evolution, our ambition is crystal clear: to keep the spirit of La Transjurassienne alive at the heart of the Jura Mountains while giving you greater clarity right from the moment you register.
10 years of adaptation
For several years now, we have had to navigate the accelerating impact of global warming and unpredictable snow conditions across the Jura Mountains.
The last 11 editions are proof of this: since 2016, the historic route between Lamoura and Mouthe has only been run in its entirety once, in 2019.
Between 2016 and 2026, across 11 editions:
- Only 1 single edition was able to run on the historic Lamoura – Mouthe course;
- 6 were held on adapted courses;
- 4 were cancelled, including the 2021 edition due to COVID-19.
Over the years, we have adjusted distances, shifted start and finish lines, and crafted contingency plans to keep bringing you La Transjurassienne whenever humanly possible.
Today, this reality is leading us to take an exciting new step forward.
Evolving La Transjurassienne to Keep the Legend Alive
Starting in 2027, La Transjurassienne will embrace a benchmark 50 km course between Lamoura and Les Rousses, in the heart of the Haut-Jura.
This decision allows us to focus the race on an area that offers the most reliable snow cover, while reinforcing the most vulnerable zones and grooming the trails to absolute perfection. It is an evolution designed to protect the quality of your adventure while preserving everything that defines the Transju' spirit: the wild Jura landscapes, the athletic challenge, the relentless passion of our volunteers, the electric atmosphere along the trails, and the human camaraderie that unites thousands of enthusiasts every winter.
It also fulfills a major commitment of ours: giving you total peace of mind and clarity as soon as you sign up.
Months ahead of race day, you will know the exact challenge waiting for you, allowing you to prepare for your Transjurassienne and plan your trip to the Jura Mountains under the best possible conditions.
The distance evolves. The Transju' spirit lives on.
