Trail Los Carabeos 2026: registration, schedules and routes

Plan your race pace

The tenth edition of the Trail Los Carabeos has already opened registrations and once again places Montesclaros on the map of Cantabrian trail running with an event that combines competition, scenery, and popular participation. The race will take place on July 26, 2026, with start and finish at the Sanctuary of Our Lady of Montesclaros, in Valdeprado del Río, and will keep the name VIII Manuel Pérez Nestar Memorial, now an established reference on the regional calendar.

The organizers have put together an extensive program, designed for runners with very different profiles and also for those who prefer to experience the mountains at a different pace. There will be five races and four adapted routes, with distances ranging from 7 to 24 kilometers, as well as specific formats such as walkers and speed trail. The result is a race that is not limited to elite athletes: it opens up as a sports festival in which the surroundings matter as much as the clock.

Montesclaros as the focal point of the race

The Montesclaros Sanctuary is not just a starting and finishing point. In a mountain race, the location is almost everything: it shapes the atmosphere, the course layout, and the participant’s experience from the very first minute. In this case, the choice reinforces the event’s unique character, because the sanctuary provides a recognizable image and a natural setting that fits the spirit of trail running: moderate altitude, paths, meadows, and woodland areas that change the race’s rhythm from one turn to the next.

The geographic reference matters for another reason as well. Valdeprado del Río has established itself as a meeting point for mountain sports in southern Cantabria, and the event builds on that territorial identity. It is not just about bringing runners together; it is about energizing a region through a race that connects sport, landscape, and the local community. That balance explains why the race has gained increasing importance within the Cantabrian calendar.

The tenth edition also arrives with the symbolic weight of a memorial. The name Manuel Pérez Nestar remains linked to the event as a way of preserving the sporting and human memory behind it. In races of this kind, proper names are not merely an institutional decoration: they help explain the continuity of the project and the emotional bond that the organizers maintain with those who have driven the race since its earliest editions.

A program designed for very different profiles

The sporting structure of this edition is designed with a clear logic: to allow an experienced runner, a family, or a beginner to find their place without leaving the same organizational framework. That breadth is one of the keys to the success of well-planned mountain races, because it avoids turning the event into an exclusive setting for specialists. Here, demand and accessibility coexist, two elements that rarely work well on their own and that, in Montesclaros, nevertheless find a balance.

The main trail covers 24 kilometers and starts at 9:30 a.m.. It is the distance that concentrates most of the competitive tension, the one that demands better effort management, a cool head on the climbs, and the ability to sustain pace when the terrain offers no respite. Just half an hour earlier, at 9:00 a.m., the walkers will set off, completing 20 kilometers along paths and landscapes of great natural appeal.

Later, at 10:00 a.m., it will be the turn of the speed trail, with a course of about 15 kilometers and an important added value: this event will be the third official race of the Cantabria Speed Trail Championship of the FCDME. At 10:15 a.m., the youth categories and the family or beginner walk will start, tackling a 7-kilometer route. That final block gives the whole event meaning, because it brings in young talent, togetherness, and a more open dimension of sport.

A race where the terrain sets the rules

Trail running cannot be understood without the relationship between effort and environment. In Los Carabeos, that relationship is felt in every section. The route crosses paths, grasslands, and forests, a landscape that from the outside may seem gentle, but in the race demands constant attention. The climbs, uneven surfaces, and changes in footing force runners to move with precision, almost like someone reading a map in real time with their legs.

The organizers have described the technical difficulty as medium, a useful label to guide participants without giving a misleading impression of the course. Medium does not mean easy. In the mountains, difficulty depends on fitness, prior experience, and the ability to manage pace changes. A 15-kilometer route can leave a deeper mark than a longer one if it packs in elevation gain, slippery sections, or stretches where the terrain truly bites.

That is why the distribution of distances makes sense. The 24 kilometers reserved for the main trail offer a more complete test, with endurance and tactical reading; the 20 kilometers for walkers allow for a more relaxed enjoyment of the surroundings; the 15 kilometers of the speed trail focus on speed over technical paths; and the 7 kilometers bring the experience closer to young runners and families. Variety is not an add-on: it is the heart of the format.

Services, safety, and very comprehensive logistics

Beyond the sporting aspect, the event stands out for the level of services offered around the race. The organizers have planned full aid stations both along the course and at the finish, with isotonic drinks, soft drinks, fruit, chocolate, and nuts. In mountain races, these details matter more than they may seem. They are not a decorative element; they make a difference when the body begins to run low on reserves and every sip counts.

There will also be showers, physiotherapy, insurance, and medical assistance, supported by two ambulances, a doctor, and a nursing team. That deployment speaks of a race that understands safety as a central part of the event, not as a mere bureaucratic requirement. In a race with varied participation, that coverage is especially relevant, because highly trained runners compete alongside others taking on their first mountain experience.

Registration also includes a runner’s bag, commemorative T-shirt, race bib with chip, timing by Uno.es, and a finisher medal. The post-race meal is also part of the day’s design and takes place in the sanctuary dining hall, with a convivial offering that extends the atmosphere of the event beyond the finish line. In popular and mountain races, that shared meal is often just as representative as the podium itself.

The social dimension of a mountain race

Trail Los Carabeos has a feature that sets it apart from other more linear races: its vocation as a meeting place. The presence of the so-called Arrastrasillas, described by the organizers as an endearing part of the day, sums up that idea well. The event is not limited to individual effort; it includes collective gestures, visible support, and a shared memory that makes it recognizable to the local public. In trail running, where effort often seems solitary, these details help build community.

That social dimension is also evident in the final meal, prepared by local establishments and served at the sanctuary itself. The format is a reminder that a rural race does not end at the finish arch. It continues in the conversation, in the exchange of impressions, in the sweat-soaked T-shirt, and in the improvised photo with the landscape in the background. They are small scenes, yes, but they explain why some races remain on the calendar while others disappear without a trace.

The role of the organizers and the Valdeprado del Río Town Council has been key to consolidating the event. When a race manages to endure for a decade, it is not just about enthusiasm; it is also about the ability to coordinate volunteers, permits, services, and sponsorship. In that sense, Trail Los Carabeos has been built as a stable fixture of the Cantabrian summer sports scene, with its own identity and an audience that already recognizes its value.

Registration, prices, and available channels

Registrations are already open and can be completed both online and in person. The official event website is www.trailloscarabeos.es, and physical registration points have also been set up at Deportes Cumbres in Santander, and at two Forum Sport stores located in Valle Real and Los Ochos. This mixed model remains useful in regionally rooted events, where part of the public prefers to register in person and another part opts for the digital process.

The prices listed on the registration platform reflect a clear range according to category: 25 euros for Trail 24K and Walkers 20K, 17 euros for Speed Trail 15K, 3 euros for the youth categories 7K, and 15 euros for the Family Walk. These prices are in line with a race that offers extensive services, timing, aid stations, and a convivial meal, while also maintaining a commitment to grassroots sport and family participation.

This combination of prices, formats, and organizational coverage helps explain why the event attracts such different profiles. There are races where the cost is focused almost entirely on the bib; here, by contrast, the participant receives a more complete experience, with logistics, atmosphere, and a carefully designed route so that the landscape is not just a backdrop, but part of the sporting story.

Why this edition could be one of the most complete on the Cantabrian calendar

The tenth edition has something of a maturity milestone about it. It is not just a round number; it is a sign that the race has gone from being a local event with ambition to becoming a recognizable reference within Cantabrian trail running. Contributing to this are its inclusion in the Cantabria Mountain Races Cup, the variety of formats, and the clarity of the organizational setup. When a race brings together those three ingredients, interest goes beyond simple registration and becomes genuine follow-up by the running community.

The date also helps. Late July places the race in the middle of summer, with long days and a mountain that changes texture under the heat. The runner must manage temperature, hydration, and the early start with a different mindset than at other times of the year. In that context, each format finds its own tone: the main trail demands patience; the speed trail, agility; the youth categories, learning; and the family walk, a calmer relationship with the route.

The race thus preserves a rare mix of sporting ambition and local hospitality. There are fast, demanding, and technical races in Cantabria, but not all manage that combination of factors that makes the day memorable for more than just the finishing time. In Montesclaros, the setting, the start structure, and the community spirit all point in the same direction: a mountain that competes, but also welcomes.

A memorial that is already part of the Campoo summer

The name VIII Manuel Pérez Nestar Memorial serves as the thread running through a race that has already found its place in the sporting landscape of the region. Here, memory is not a static label, but an active presence that gives continuity to the event and connects it to its history. In local sport, that kind of permanence has journalistic value and emotional value as well.

Trail Los Carabeos has managed to build a recognizable identity without losing flexibility. It remains a mountain race, but also a popular event, a day of togetherness, and a useful fixture for those looking for summer challenges in Cantabria. That versatility, together with the solid organization and the appeal of the location, explains why each edition draws more interest from the moment registration opens.

What arrives in July is not just a race with several routes. It is an event that reflects very well what trail running has come to mean in many parts of Spain: sport, territory, memory, and community. In Montesclaros, that blend returns in a proven format and with enough support to keep growing without losing its character as a mountain event that is close, demanding, and deeply local.
