La Caldeniacienne

On September 6, 2026, the 38th edition of one of France's most beloved trail running events will take place. This year’s festival features both a 10K and semi-marathon course that wind through lush forest trails for nearly their entire length, offering runners an immersive experience in nature.
The event is designed to challenge participants with its varied terrain while also celebrating the beauty of the surrounding woodland. The trail courses are meticulously crafted to showcase the region’s natural splendor, providing a picturesque backdrop as competitors navigate winding paths and serene landscapes.
In addition to the competitive races, there's also a family-friendly hike available for those who want to enjoy the scenery without racing against time. This event is an ideal opportunity for runners of all levels to connect with nature while testing their endurance on challenging but rewarding trails.
The atmosphere at this race promises to be lively and supportive, reflecting its status as one of the region’s premier sporting events. As participants push themselves through the scenic routes, they will encounter cheering crowds along the way who are there to share in the excitement.
Runners should expect a mix of elevation changes that add an extra layer of challenge to their efforts while also providing stunning views from high points on the course. The semi-marathon route extends beyond the 10K distance but follows similar terrain, ensuring consistency for those looking to tackle both events.
This event is more than just a race; it’s a celebration of running and community spirit in one of France's most beautiful settings.
