Martijn van de Ven
Martijn is the ever-cheerful and energetic Brabander on our team, instantly recognizable by his enthusiasm and endless stories. Sitting still? He's not one for that. And neither is being quiet.
Whether it's running or just chatting on the trails, Martijn is always up for it. His passion lies in trail running. He enjoys narrow singletrack, steep climbs, and fast descents. For Martijn, it's not just about the kilometers or the elevation gain, but rather the combination of sport, nature, and conviviality. The adrenaline of a challenging climb, enjoying the view from the top, and then relaxing together in the sun—that's the perfect day for him.
Besides his role as a route guide at Alltractive, Martijn enjoys spending time with friends. He's a real lifesaver, both during the trails and afterward. He makes everyone feel welcome and always knows how to energize the group with his infectious energy. Anyone needing a break? Martijn will chat them up – with a smile and a joke.

And if anyone in the group is having a hard time, Martijn will happily talk you through it with all his energy!

Joris Wiegersma
Joris is an old punk from Utrecht who absolutely loves trail running (playing outside). Besides his job as a caretaker on a beautiful estate on the slopes of the Utrechtse Heuvelrug, his favorite activities are hiking and trail running in the mountains, and dancing in the mosh pit, of course. The mountains and nature make him feel completely zen, so when his internist suggested he start exercising a few years ago, the choice was quickly made: skipping into the woods to spend the whole day outdoors among the birds and the plants. The distances quickly became longer and longer, and he prefers to be outside all day. And whether that means running 25 or 75 km straight doesn't really matter, as long as it's beautiful.
For Joris, enjoyment is paramount. The sight of a chamois, ibex, or marmot gives him goosebumps, and as soon as the steep slopes loom before him, a smile spreads across his face. Technical descents make him absolutely thrilled, and he loves taking people along on them. Skimming down the mountains together is the best thing there is!
Jurjen Diepeveen
Jurjen lives in the heart of the Alps, in the vibrant city of Innsbruck. From his front door, he can be among the mountain peaks in just minutes, and that's precisely where he feels most at home. Whether it's a leisurely hike or a technical trail run on alpine paths, Jurjen enjoys exploring together and sharing knowledge along the way.
What immediately strikes you when you're out with him is his calmness and mountain knowledge. He enjoys engaging in lively conversations along the way, but also knows when it's time to be quiet and simply enjoy the view. Jurjen has already run several challenging trails in the region, including the Kaiserkrone Marathon Trail and the Innsbruck Alpine Trailrun Festival. He knows better than anyone how to navigate the mountain landscape safely and with enjoyment.
His guidance is calm, attentive and inspiring, perfect for anyone who wants to discover the mountains in a sporty way with Alltractive.
George Kingma
George is the swimming coach on our team. His roots are in Rotterdam, but he's lived in Brabant for over 30 years. This has allowed him to combine the Rotterdam "no nonsense, just do it" mentality with the Brabant conviviality.
In his younger years, he played water polo and competed in swimming at Vlaardingen's VFC. In the mid-1980s, he started running, with the marathon as his longest distance. His personal best in Rotterdam was 3:48:16. He also competed in mountain running, cross-country skiing, and fell runs in the UK.
Besides running (which has been a bit of a back burner lately), George has trained with the Breda Lifeguard Brigade and was a swimming trainer and coach at SBC2000. He also provided swimming training at TVB (Breda Triathlon Association). He is also an international official for the NTB (Dutch Triathlon Federation) and a referee for the KNZB (Royal Dutch Triathlon Federation).
His love goes out to open water swimming, where he has trained and coached several national and international athletes.
It's clear that this is a family of water rats; son Gordon is a lifeguard on the beach in Haamstede and daughter Maya is an Olympic triathlete.
With great pleasure and dedication he now provides swimming training at Alltractive, where personal attention for each swimmer is paramount.
Noah Snel
Noah's greatest fear in life is that we forget how beautiful the world around us is, and how much freedom, peace, and inspiration the silence of this impressive planet can give us if we are open to it. As someone who spent most of his life in bed until the age of 24 (back then, he enjoyed the necessary late-night alcoholic socializing), he began to appreciate the mornings outdoors starting at age 25. Moving to South Africa helped with this. His mornings there consisted of walking or running along the South Atlantic Ocean (with daily dolphin and whale spotting) or hiking or trail running in the incredible splendor of Table Mountain National Park. He never looked back. Being active in nature became a priority for him; he can no longer imagine a life without it. Noah's goal is to make people more aware of this. He feels that in this modern age, dominated by screens, we are more occupied with the online world than with the real world. As a young millennial who has experienced both eras and can still clearly remember the rise of social media, Noah dares to say with certainty that the real world, the world with the splendor of nature, with all its pristine beauty, is far more impressive, liberating, inspiring, and motivating than the world through screens. He hopes that we, as humanity, will soon come to realize this again.
Sara Beaumont
My name is Sara Beaumont, and I live in a picturesque village in Groningen, on a small farm surrounded by our horses, dogs, cats, and chickens.
Unlike my colleagues, I prefer covering my kilometers on horseback or by mountain bike.
You will therefore regularly find me in the nature reserve surrounding my home, or riding one of my horses or my mountain bike along the sandy paths and small roads.
In my free time, I enjoy archery,
Whether from the ground or from my horse, I hit many a bullseye.
I also love traveling around with my husband in our camper van.
We specifically seek out wooded areas for both hiking and mountain biking. We can also regularly be found on Texel enjoying the most beautiful island in the Netherlands, where we discover new beautiful spots every time.
I hope to work together with the Alltractive team to encourage people and companies alike to get moving, and to experience a wonderful time with one of our tour guides in the most fairytale-like places in the world.
Whether it's hiking, walking, trail running, or team building, I love being able to get people excited about it.
