International Mountain Leader

A bit about me

I’m originally from the Netherlands and after studying Physical Therapy in Belgium, I moved for three years to Guatemala. I volunteered in a project for children with disabilities. In my spare time, I climb volcanoes and enjoy taking part in triathlons. In Nicaragua I ran my first 100 km ultra trail and straight away I fell in love with trail running!

In 2013, I moved to Switzerland and I finished my International Mountain Leader course here. For most of that time, I lived right in the middle of the Alps, in the mountain village of Saas Fee. I spent my time outside in the mountain trail running, alpine climbing, nordic skiing and lots more!

I recently moved with my dog to Stalden, a small village between the Saas Fee and Zermatt Valleys in the Valais canton, where I run my own physical therapy clinic.

Trail running background

I like technical races like Scotland’s Glen Coe race, Tromsö in Norway, and Trofeo Kima in Italy. But, I also run long distance races like the Mont Blanc Marathon 90 km and the 125 km race in the Canary Islands, Transgrancanaria.

Why I love guiding

I love spending time in the mountains and love to inspire others to do the same; whether it is to improve your running skills, showing you new areas, or just get inspired by the beautiful nature around us!

Breezy Mornings Merino Beanie

Fact: We’re kind of picky about our beanies. Some are not thick enough, some are too thick. Some of us (no names, please) have big heads and find some big-name outdoors brands (no names, please) to have, well, not enough volume under the dome.
