The French-Swiss Marathon: a new running event in 2027
Two countries, one border, and 42 km of adventure!
On September 18 and 19, 2027, the Franco-Swiss Marathon will make its grand debut in the heart of the Jura Mountains. A new sporting event organized by Trans’Organisation in collaboration with Vallée de Joux Sports Events.
The event promises a unique experience between Station des Rousses and the Vallée de Joux.
Registration opens on Thursday, November 19 at 12:00 PM!
One marathon, two countries, a unique adventure!
Imagine a marathon where every kilometer reveals new scenery, between lakes, forests, and mountains. A road course in the heart of preserved nature, with a special feature: connecting France to Switzerland on foot!
Starting from La Cure at Station des Rousses, marathon runners will set off on a 42.195 km journey through the Franco-Swiss Jura landscapes. After running alongside Lake des Rousses and through Bois-d’Amont, they will cross the border into the Vallée de Joux, renowned for its panoramic views and watchmaking heritage.
With the Dent de Vaulion as a backdrop, runners will continue their journey along Lake Joux, all the way to the finish line in Les Charbonnières.
A road-based nature marathon, blending athletic challenge, discovery, and shared moments!
Distances for every running enthusiast
Because the adventure isn't limited to 42.195 km, the Franco-Swiss Marathon offers several formats so that everyone can find their own challenge:
- Marathon – 42 km: the great Franco-Swiss crossing, from La Cure to Les Charbonnières.
- Half-Marathon – 21 km: an immersive run in the heart of the Vallée de Joux, between watchmaking heritage and magnificent landscapes.
- 12 km: a fast, rolling course with Lake Joux in the background.
- 5 km: an accessible distance to soak up the event's atmosphere.
- Kids' Races – 1 to 3 km: giving younger runners the chance to experience their own running adventure, too!
Festivities kick off on Saturday, September 18, 2027, with the 5 km and kids' races, ahead of Sunday's main events on September 19.
Much more than a race: a weekend to share!
The Franco-Swiss Marathon is also an opportunity to discover an exceptional region spanning two countries.
Between the landscapes of Station des Rousses, the shores of Lake Joux, and the iconic villages of the Vallée de Joux, the event invites runners and supporters alike to enjoy a truly friendly, athletic weekend.
An expo village will also welcome visitors on September 18 and 19 to extend the experience.
