Transju'Trail: Trail running in the heart of the Haut-Jura
The summer version of the legendary Transjurassienne, the Transju'Trail is a trail running event organized by the association La Transju' in the Haut-Jura. Every June, thousands of runners set off on the trails of the Jura massif for trail races ranging from 5 to 65 km, crossing spruce forests, high-altitude pastures, wild valleys, and ridges offering spectacular panoramas.
Races for all levels
The Transju'Trail offers a complete range of races adapted to all runner profiles:
- 65 km Trail: the ultra event for experienced runners, with significant elevation gain across the Jura massif (limited places)
- 42 km Trail: the trail marathon format, the event's benchmark
- 25 km Trail: an accessible format for intermediate trailers
- 10 km Race: ideal for getting started in mountain trail running
- 5 km Race: discovery format, open to all
- 15 km Hike: walking route to enjoy the scenery without the competitive aspect
A course between Lamoura and Les Rousses
The Transju'Trail courses wind through the territory between Lamoura and Les Rousses, following the marked trails of the Haut-Jura. Runners cross varied and preserved landscapes: coniferous forests, peat bogs, wooded pastures, high-altitude lakes, and panoramic ridges offering views of the Alps and Mont Blanc on clear days.
A festive and friendly event
Beyond the competition, the Transju'Trail is a truly festive event that enlivens the Haut-Jura throughout a weekend in June. A start village with partner stands, local food, and entertainment welcomes runners and their companions. The atmosphere is warm and family-friendly, in the mountain spirit of the Haut-Jura.
