Mulo de Carga

A biking community with values

I have dedicated my entire conscious, independent life to bicycles.

Time, energy and money invested in parts, bikes, travel, and the pursuit of meaningful experiences on two wheels.
That dedication has shaped my lifestyle, created unforgettable memories, and led me to the Pyrenees: a place where mountain biking feels limitless and reaches its purest form.
After more than fifteen years on a bike, I still experienced something that elevated my understanding of what mountain biking can truly be.
This is the story of how that happened — and why I do what I do today.

One summer afternoon call from a friend set me on a mission.

The next day 4 friends started the riding experience that has marked me the most during my cycling career. That was to ride around the Aneto peak in the Pyrenees. A two-day loop with a total of 100 km and 6.000 m of elevation taking on the most remarkable places and trails of the mountain range.

This experience discovered another dimension to me. One dimension of cycling where effort, silence and commitment mattered more than speed or results. It left me thinking of what other possible missions were achievable in the area. I went and did all the routes I could during that summer until it snowed in the high altitude terrain. During winter time, there was already excitement for the next summer season. I couldn’t stand still without that style of rides and soon found myself exploring alternative routes where there was a demand for “hike a bike” climbs. These usually mean more engaging trails and interesting sites. My adventures had created anticipation among riding buddies, the collective and my followers. Many were asking advice on undertaking their own or to join one of the missions.

All this together had awakened a new purpose in me.

The aim was clear: I wanted more people to feel what was like to loop the highest peak of the Pyrenees. Feeling small but alive. Exhausted yet fulfilled.
A tiny part of the vastness of the world is what we are, although we tend to think differently. Only certain experiences force us to be grateful for the mere capability of simply standing there contemplating. This was one for me and I wanted to share it.

The Aneto loop.

The Anteto loop is not a simple task, it requires a certain level of on the bike skills and a fitness level that only commitment and high motivation can take you to. Hard, but not impossible for many.
As narrated, my experience in these alpine cycling missions was brief, but intense. I was aware of what was required to accomplish that milestone of a ride and developed a program consisting of a progression that would prepare people for that aspiring adventurous ride.

This is how I came up with the “Mulo de Carga” squad, a name inspired by the act of carrying the bike when pedalling is no longer an option. It is a group of individuals willing to take the time and effort to reach remote places they never thought were even rideable, with the bike on their backs.

The first ride

Therefore, already in April, the first community ride of Mulo de Carga happened. I recently moved houses, to be closer to the dear mountains. There I was able to receive a group, host it with a specialty coffee, go for the initial alpine style ride and end with a bbq. A perfect first contact day for the ones that do not usually push the bike up steep singletracks. With this I was sharing two of my passions (bikes and coffee) and the emotion of these high-impact experiences. In nature, riding bikes, contemplating astonishing landscapes.

This ride only covered 35% of the “numbers” to be achieved during the final goal, but that would select riders and motivate others to join. We hiked the bike for only 30 minutes but laid the first stone for the group members. Two initiation experiences were hosted. They drove people with hunger for more and kept away others with less ambition. A group was formed.

Slowly, the ice was melting in the higher altitude ground

We were now able to continue the logical progression. We then covered the Comodoto peak in Bielsa with 2354m of elevation for which we had to carry our bikes for an hour. It was well worth it, the trails of Bielsa Trocs were awaiting the crew.
Later on, we went to Estibafreda, in Benasque. We doubled the time walking the bikes on our backs to summit the 2700m peak to descend one of the most iconic alpine trails in Spain: Sierra Negra.

The result of these rides was a group of motivated riders that were driven and ready for the Aneto loop. They had already had a taste of what sort of effort and terrain was to come and felt ready for tougher goals. We were ready to set a date.

Mulos de Cargo are born

The 8th of August of 2025 the group consisting of eight “Mulos de Carga” departed from Vielha. Our route was ambitious; I created a track where we were merging a 2 day ride in one, supporting us with a shuttle that would cover asphalt climbing. This, meaning we would be fresher for the hardest bit and less time consuming, skipping the non meaningful part of the loop. The ride consisted of 2 big climbs and descents, with 1500 meters of elevation to be hiked with bikes in our backs. We had all day and more than 12 hours of light.

The plan was done: route marked, feeding stations sorted and good weather.

We went for it. It took us almost 12 hours in total to cover 50 kilometers and 2500 meters of elevation gain. We rode bikes at sunrise and sunset, descended inconceivable flow trails above 2500 m with astonishing views and went through a vast variation of emotional states. All members remained together, kept the pace steady but consistent and reinforced one another to stay in a better and high-energy mood. This would be key to complete the ride with no mishaps and add a memory that all of the group will remember as one of the best days we’ve ever had on the bike.

Moving into another year and a new season of alpine riding, the community consolidates. Having set an example, others will be encouraged to join our experiences. A squad that shares values and ambitions and above all, a passion. Passion for an object that provides beyond transportation or mere joy- it becomes a tool.
For Mulo de Carga, the bike allows self expression and life experimentation to reach new and unconceived levels. A path that converts cycling into part of who we are.

Practical notes for those feeling the call.

All of these experiences take place in the heart of the Pyrenees, a region that’s surprisingly accessible via three major airports: Barcelona, Madrid, and Toulouse. From there, a network of iconic alpine riding areas unfolds, each worth at least two to three days of exploration – from Valle de Benasque and Valle de Pineta to Vall d’Aran (Vielha) and Pallars, including Pobla de Segur and Tremp. Each zone has its own character, terrain, and trail culture, supported by passionate local trail associations like Puro Pirineo, BielsaTrocs, Lo Podall, Trenkabikers, and Aran Bikeparks. While Pallars offers year-round riding, the higher alpine areas are best enjoyed between May and October, when snow retreats and the mountains fully open up. The most ambitious and iconic mission, the Aneto loop, both begins and ends in Vielha, linking legendary riding locations such as Sierra Negra, Comodoto Peak, the Tremp and Pobla valleys, and Vall d’Aran into one unforgettable experience. These are among Spain’s most renowned summer riding destinations, all equipped with bike-friendly infrastructure including dedicated hotels, shuttles, guiding services, and active trailwork communities.

For those curious to follow or join future missions, updates for 2026 can be found at @mulodecarga. And when it comes to equipment, one bike has proven itself as the ultimate tool for these rides: the Firebird, striking the perfect balance to fully unlock long, technical alpine descents after the hardest climbs.
