The GTLC is more than just a race.

It's a state of mind.

Since its inception, the Grand Trail des Lacs et Châteaux has been built around a simple idea: to offer challenging courses set against stunning natural landscapes, while maintaining a personal and friendly atmosphere.

Over the years, thousands of runners have come to explore this region and share in this unique experience.

A spirit of simplicity

The GTLC remains true to a simple vision of trail running.

• Authentic experiences.
• Nature trails.
• An organization that supports runners.

Here, it’s not just about performance.

It’s also the joy of running, sharing, and experiencing an intense moment in the heart of nature.

An event we’ve built together

Behind every event, there is an organizing team, partners, and, above all, a large community of volunteers and enthusiasts.

Since the first editions conceived by Christophe Libin, the GTLC has grown thanks to this collective energy and the support of the many people who bring the event to life year after year.

This human touch remains one of the GTLC’s strengths.

A New Chapter: The GTLC Backyard

With the GTLC Backyard, the GTLC is exploring a new kind of challenge.

A format that differs from traditional trail races, yet remains true to the same values:

• authenticity
• requirement
• respect for the land
• team spirit

Distance is no longer a journey across a landscape, but a repeating loop in which every hour becomes a new beginning.

The same passion

Whether you're hiking along the trails by the lakes and castles or up on the heights of Baraque de Fraiture, the principle remains the same.

• Create challenging races
• Share memorable moments
• And make people want to come back

That’s the GTLC spirit.

Laurent, in charge of the race HQ, but also a signaller and much more! With a great sense of humour, his analysis is often very accurate, constantly challenging and always aimed at improving the GTLC spirit.

Most of the time, Olivier is only in his repatriation vehicle. Even if he doesn't feel the atmosphere of the site, the adrenalin, he meets every runner who has a story to tell, wherever they come from. He receives thanks and praise for the organization, the refreshments, the kindness of the volunteers and, above all, for the fact that, exhausted and injured, he brings the runners to safety and drives them back!

His hands and his head are gold...
He coordinates the entire Ovifat site like a true site manager.
He's the one who sets up and takes down everything!

She uses her knowledge for the benefit of the GTLC and the safety of all runners on the GTLC trails.
Her role: to take your call at race HQ, reassure the runner or determine what help he or she needs.

Calculating food supplies, routing, managing teams of volunteers at strategic feeding points and living quarters, she's the one! Everything has been thought out and improved from one edition to the next... You won't miss a thing!
