We are
Element X
A Belgian team that builds and leads wilderness expeditions: expedition leaders, X Guides and a basecamp that follows every expedition closely.
More than 300 entrepreneurs on expedition since 2022
At Element X we challenge people to break free from the familiar. We take entrepreneurs, professionals and leaders into the wildest nature worldwide: more than thirty expeditions on six continents, off grid and in small groups, after months of preparation.
It is about more than adventure alone. In unspoiled landscapes there is space to slow down and to reconnect with nature and with yourself. That builds resilience, opens new perspectives and sets something lasting in motion.

Thomas is the operational heart of Element X. With his analytical eye, calm and precision he keeps expeditions on track. He safeguards quality, builds international partnerships and makes sure our operations run tight and reliable.

Sarah is your point of contact from sign up to return: communication, gear, the preparation programme and basecamp. She is also an expedition leader herself. On Sundays you will find her on the trail running circuit. Her dog Mo has more or less become our office dog.

Jolien is a graphic designer and adventurer. With her eye for storytelling she brings our expeditions to life in design and photography.

Simon is a paramedic with the fire service and a former paracommando. The calmest member of the team: authentic, gentle and always ready to lighten your backpack.

As an adventure racer, Marie-Louise spends days on end in extreme conditions with minimal support. Her leadership is calm and robust, always focused on safety and the team.

Erik worked fifteen years as a physiotherapist in the army, in the Netherlands and on operations. Stoic but caring, both with a physical injury and for your mental support.

Fred is an experienced expedition leader who knows the most remote corners of the world. As a researcher and team developer he combines technical knowledge with grounded, strategic leadership.

Landry lives for adventure. A former underwater welder, he combines technical skill with strong social intelligence, always with humour, curiosity and respect for the environment.

Wouter has a natural way of leading and brings groups together towards one goal. His calm presence creates a safe environment in which participants grow and work together.

Renske is an outdoor professional with a deep love for nature. On rock, on water or in the air she moves with technical strength, always with an eye for safety and the team.

Finn is a bushcraft and survival expert with a deep knowledge of plants and animals. Calm and empathetic, he takes groups into his world of nature and self reliance.

Maarten loves cooking outdoors. With pure, local ingredients and plenty of creativity he turns every meal around the fire into an experience.

Michiel works with local, seasonal ingredients and translates the surroundings into flavour. Around the fire or on location he cooks with craft and respect for product, place and team.

Our office is at Kasteel Borgwal in Gavere. This is where groups meet for their kick off and technical training: building shelters, filtering water, packing backpacks and training with weight on the towpath along the canal.
During the expedition our basecamp in Belgium follows your group 24/7. Your first conversation can take place here, or online if that suits you better.
