The perfect introduction to the world of trail running.

The GT12 features a 12-kilometer course with 418 meters of elevation gain. It’s an accessible race designed for those who want to try trail running in a natural, supervised setting, either alone or as a pair.

Shorter than previous editions, the GT12 offers a more direct experience while retaining the essence of the GTLC Winter: varied trails, dynamic terrain, and a chance to immerse yourself in the heart of the Ardennes countryside.

With its mix of forest trails, open-country sections, and slightly technical stretches, the course lets you get your bearings, pace yourself, and get a taste of what trail running is all about.

The highlight of the race: the legendary climb up the Ovifat ski slope. A memorable finish—accessible yet challenging—that will cap off your effort and leave a lasting impression.

When running solo, everyone moves at their own pace, focused on how they feel. When running as a pair, the experience is shared—with encouragement, mutual support, and the joy of running together along the course.

The GT12 is a first-time experience, a first step, or simply the joy of running in the great outdoors over a short, fast-paced distance.

A great way to get started… and often leaves you wanting to take it further
