We are privileged to live right in the middle of these amazing trails and to be able to ride them from our front door. We would love to guide you on our “home trails” and help you to experience Zona Zero and some of the EWS Stages.

The trails here are all natural. The climbs can be steep and the descents are rocky but they have been well thought out and flow beautifully. (We can arrange a shuttle that brings you deeper into the backcountry).

Riders wishing to ride technical XC/ Trail, we have got you covered as well. We have selected a combination of “Pistas” (Dirt Roads), beautiful trails and flowing singletrack that promises you a great day on the bike.

On every ride you can take in the amazing mountain views and discover the many ancient  abandoned villages and churches that we have in the area.

Who is your guide? 

Meet Jeroen Spoelstra


I am a MIAS (Mountain Bike Instructors Award Scheme) certified mountain bike guide.I have a First Aid diploma from the Red Cross in Huesca, Spain, where the focus is on providing suitable First Aid to casualties in mountainous terrain.My university teaching degree helps me when guiding because it has given me experience working in front of large groups of people and taught me how best to coach people.

I guide you in fluent English or Dutch (Nederlands) and a little Spanish (I’m still learning that one!)



Hello my name is Jeroen Spoelstra. I moved to Ainsa the day before New Years Eve 2017/2018 with my wife Marce and we have a little boy whose name is Oliver. As a Dutch guy I rode a bike before I could walk properly! I have been riding mountain bikes for the last 25 years. The mountain biking in and around Zona Zero is some of the best I have ever ridden. In my short time here I discovered many trails & there are many more to find and explore. I am looking forward to show you all the amazing trails this part of the Pyrenees has to offer.


AND who are you? I'd love to ride with you!

The Collaborators

We are happy to be associates with the Zona Zero platform. They make it possible for us to ride the trails and we support them fully. Since the beginning of this year we started riding with Commencal. We hope to be riding more Commencal bikes in the future as the company grows. Inizia introduced us to other parts of the Spanish Pyrenees and helps us understand the market and the local biking community in the Pyrenees.
