A magical place

An exceptional region

Breathtaking landscapes

I was born of the imagination and passion of an enthusiast. He brought me up with oak, the oak of our beautiful forests that I love so much, the oak from which the best wines are made, the ones that age without compromise, with taste. I've written a few pages about the Trail in Belgium, but also some of the most beautiful swear words of suffering. I've shared my beer with everyone, along with our memories, our experiences, our tears and, above all, our joys. Today, I'm sheltered by a whole band of friends whose reason knows no boundaries and whose passion knows no impassable mountain. I've grown up, I've matured, and I can't wait to see you again, because life is worth living, but together. The GTLC

GTLC Winter 2021 changed my career. As a pro triathlete I wanted to do something new and entered the GT35. After 20km I was completly destroyed and thought what a hell of a race - how stupid is trail running? But a few minutes later I said: holly shit, that was awesome!!!! From that point I fell in love with trail running and the reason was GTLC because of the great course, the organization and the atmosphere. And that's the reason why I also become a trail race organizer. Thank you GTLC

The GTLC is a must for trail running in Belgium. The courses are splendid and varied, the organization is top-notch and the start site at the Ovifat ski slope lends itself perfectly to a trail setting. I've been taking part in the Summer and Winter editions for several years now. Whether it's for the competition or for the beauty and atmosphere, over short or long distances, it's well worth taking part!

This site is the most beautiful on every level, the landscapes, the colors, the kilometers go by without you even realizing it, there's always so much to marvel at, the routes are rewarding both for surpassing yourself and for the human adventure they contain, everything is out of time, you feel like you're in a bubble far from everyday life, you have to experience it at least once in your life... and when you get a taste of it, you come back again and again, thank you for these superb moments.

GTLC 2017... zowat 0°, 24 gelletjes, 8 liter water... maar vooral een fantastische herinnering aan mijn eerste trail langer dan 100km, op een prachtig en gevarieerd parcours, met al het moois dat een Belgische trailwedstrijd te bieden heeft.
