Ultra Trail Serra de Montsant 2026: complete guide to the race

Plan your race pace

The Serra de Montsant is once again putting itself on the map of Spanish trail running with an event that combines toughness, scenery, and very clear logistics. The 2026 edition will take place on October 10 and 11 in Ulldemolins, in the province of Tarragona, and keeps the formula that has made this event recognizable: a flagship long-distance race, a mountain marathon, intermediate distances, and shorter options designed for different experience levels.

This is not an event of decorative numbers. The main race goes beyond 63 kilometers and adds 3,470 meters of positive elevation gain, while the program also includes a stage format totaling 88 kilometers, a 44-kilometer mountain marathon, a 25-kilometer distance, another of 11 kilometers, and an introductory 7-kilometer start. Everything takes place in a highly demanding setting, with a natural park that commands respect from start to finish.

A trail classic in the heart of the Priorat

The strength of the race lies in where it begins. Montsant is not a backdrop; it is the sporting narrative itself. The natural park features narrow trails, climbs that punish the legs, and terrain that alternates runnable sections with others where the pace must necessarily become economical. That mix explains why the race has grown in importance year after year since its debut in 2009.

The organizers present the event as a meeting point between the territory, the surrounding villages, and the runners. In practice, that translates into a race with its own identity: Ulldemolins as the start and finish point, aid stations placed with a certain mountain logic, and a format that forces runners to think about each section. It is not enough to push; you have to manage.

The appeal is not just in the distance. It also lies in the character of the route, in the feeling of running among rock walls, terraces, and trails that rise and fall as if the course had been drawn with a restless line. For trail runners, that kind of setting is a complete test: endurance, mental strength, and technique.

What the 2026 program offers

The 2026 edition concentrates activity into two very distinct days. On Saturday, the 63-kilometer ultra, the 44-kilometer marathon, and the 88-kilometer stage format are contested; on Sunday, the 25-kilometer distance, the 11-kilometer race, the trekking mode, and the 7-kilometer introductory start take place. The distribution is no coincidence: it reserves the biggest effort for the start of the weekend and leaves Sunday as a more accessible block open to a variety of profiles.

The stage race, known as the Montsant Stage Run, adds 63 kilometers on Saturday and 25 on Sunday to complete 88 kilometers. It is a two-day proposal that increases the overall load, but also changes the mental logic of the race. It is not just about finishing; it is about managing the hours, recovering between stages, and returning to compete with a clear head the next day.

The variety of distances broadens the reach of the event without diluting it. The 44-kilometer marathon keeps the bar high for those seeking a serious but not extreme challenge, while the 25K and 11K bring the natural park closer to runners less accustomed to major elevation gain. The 7-kilometer start also serves as an entry point into the mountain atmosphere for more modest profiles or families with basic experience.

Technical details that define the real effort

The main ultra is run over 64.3 kilometers and 3,470 meters of positive elevation gain. The start is set for 8:00 from the pool in central Ulldemolins, and the time limit is 15 hours. The route includes several aid stations and a sequence of sections that distribute the effort. It is not a course to improvise on, because the mountain here punishes every excess of enthusiasm.

The 44-kilometer marathon starts at 8:30, also from Ulldemolins, and accumulates 2,343 meters of positive elevation gain. The time limit is 10 hours. In trail-running terms, these figures place the race in a notably demanding zone: enough volume to require specific preparation, but still manageable for runners who have already taken part in mid-distance mountain races and know how to read the climbing pace.

The 25-kilometer distance is not just a shortened version. It totals 24.7 kilometers and 1,263 meters of positive elevation gain, with a 9:30 start and a maximum of 6 hours to complete it. It is a compact, intense race and one that is highly representative of the Montsant terrain, where the ratio between distance and elevation gain makes it clear there will be no respite.

The 11-kilometer race adds 621 positive meters and is scheduled to start at 10:00. The 7-kilometer start begins at 10:05, with 240 positive meters. In both cases, the route retains its mountain identity, although in a much more approachable format for those making their debut or wishing to participate without long-distance preparation.

Aid stations, self-sufficiency, and gear checks

One of the most defining features of this race is self-sufficiency. In the ultra and the marathon, runners must manage hydration and nutrition well between aid stations. The organizers describe the event as accessible within its toughness, but make it clear that each participant assumes an important part of their own on-course logistics.

In the 63-kilometer ultra, aid stations appear at Tres Juradets-Sant Bartomeu, the Margalef dam, Fonda Margalef, Sant Salvador, La Morera de Montsant, Albarca, Santa Magdalena, and the finish. The 44-kilometer marathon passes through Tres Juradets-Sant Bartomeu, La Morera, Albarca, Santa Magdalena, and the finish. In the 25K, the stations are concentrated in a shorter sequence but are sufficient for an effort of just over six hours maximum.

The environmental regulations are another central element. There are no plastic cups anywhere in the race, and each runner must carry their own reusable container. The organizers even offer the option to purchase a specific 250 cc cup. At liquid points, water is the reference; at fuller aid stations, other products are added, although some can only be consumed on site.

External assistance is also limited. In the ultra and the marathon, outside support is only allowed at specific points and under very precise conditions. The idea is to reinforce that sense of autonomy, almost of a crossing, that defines major mountain races. There is no room to turn the race into continuous assistance; the runner must solve much of the route by themselves.

Prices, deadlines, and registration

The 2026 fees are staggered by date ranges. For the 88-kilometer Montsant Stage Run, the promotional price is 100 euros between February 14 and March 31, rises to 115 euros between April 1 and September 20, and reaches 130 euros from September 21 to October 4, with a T-shirt subject to stock in this final period.

The 63-kilometer ultra starts at 80 euros in the promotional period, moves to 90 euros in the second period, and reaches 100 euros in the final one. The 44-kilometer marathon starts at 60 euros, then 70, and finally 80. The 25-kilometer distance is priced at 35, 38, and 41 euros depending on the period. The 11-kilometer race costs 25, 28, or 31 euros, while the 7-kilometer introductory start is listed at a promotional price of 15 euros, a 20-euro fee in the next period, and a no-T-shirt option for 12 euros available only on October 5 and 6.

Registration includes more than just the bib. Depending on the distance, it includes a technical T-shirt, runner’s bag, aid stations during the race, finisher medal, gifts, and services such as timing, live tracking, medical support, and physiotherapy at the finish for the longer distances. In the case of the 7K, the race does not include chip timing or scoring, because its focus is clearly more recreational and introductory.

The race also includes temporary insurance for those who are not licensed members. The additional fee is 12 euros for the stage race, 10 euros for the ultra and marathon, and 4 euros for the shorter distances. In addition, cancellations and bib changes have their own conditions and penalties, with administrative details worth reviewing before completing registration.

Scoring, indexes, and sporting value

Montsant does not live in isolation in the trail calendar. The 63-kilometer ultra awards 3 ITRA points and is part of the UTMB qualifying system in the 100-kilometer category. The 44-kilometer marathon grants 2 ITRA points and also counts toward UTMB 50K. The 25-kilometer race adds 1 ITRA point and enters the circuit with qualifying value in its equivalent distance. The 88-kilometer stage race provides 4 ITRA points and a 100K UTMB Index.

That structure makes the event more than just a local calendar race. For runners looking to add points, assess their mountain condition, or set a season benchmark, Montsant has clear value. The combination of elevation gain, technical terrain, and distance makes it especially useful as a serious test, without reaching the excess of a high-mountain ultra.

The makeup of the field also speaks to its reach. In recent editions, an international profile has been described, with runners from different countries and significant female participation. It is not a race closed in on itself, but one that attracts both those who know the territory and those who want to discover it through sport.

Start, schedules, and weekend logistics

Everything revolves around the pool in central Ulldemolins. That is where the starts and bib pickups are set, with an organization that concentrates movement in a few points to simplify the participants’ experience. On Friday, bibs are collected in the afternoon for the longer distances, and on Saturday and Sunday new pickup windows open according to the schedule.

On Saturday, the ultra starts at 8:00 and the marathon at 8:30. Marathon trophies are awarded at 4:00 p.m., and the finish closes at 6:30 p.m. In the ultra, the awards ceremony is scheduled for 7:00 p.m. and the finish closes at 11:00 p.m. On Sunday, the 25K starts at 9:00, the 11K at 9:30, the trekking mode at 9:31, and the 7-kilometer start at 9:45 or 10:05, depending on the source and the modality.

For the runner, this sequence matters as much as the course profile itself. Arriving with time to spare, collecting the bib without rush, checking mandatory gear, and understanding where the support points are reduces the pre-race noise. In a mountain race, logistics are part of performance; poor organization the day before weighs more than it seems once the climbing starts.

Environmental rules and race culture

The environmental commitment is not just a communication flourish. The race maintains the FEEC’s Petjada Verda commitment, and this is reflected in concrete measures such as eliminating disposable cups, promoting reusable containers, and controlling outside assistance. The mountain is cared for not only through words, but through the small gesture repeated thousands of times: drink, refill, continue.

That approach fits well with the image projected by the Serra de Montsant. The natural setting demands respect and offers a very pure trail experience, without artifice. Those who run here usually remember not only the views, but the tone of the day: a harsh, bright, and in places dry landscape, with the feeling of a race that seems closer to a crossing than to a conventional sporting circuit.

The presence of trekking and introductory options confirms that the event wants to open doors, not close them. Alongside the more demanding races, the program leaves room for those who prefer to hike or start with shorter distances. This coexistence of levels explains part of its continuity: the event does not end with the ultra elite, but builds an entire weekend around the mountain.

Montsant, a setting that weighs on the legs and in the memory

Some races are measured by the clock and others are understood by the terrain. Montsant clearly belongs to the second group. The toughness is present, yes, but not as mere punishment. It appears as a way of organizing the effort and forcing runners to look closely at the landscape, because here every climb and every descent changes the way you run.

Among the rock, the trails, and the small settlements in the area, the runner links together very different scenes in a single day. Over the long distance, that mosaic becomes a story of endurance; in the 25K or the 11K, the narrative is shorter, but it keeps the same mountain pulse. The race works because it maintains that balance between accessibility and demand, between beauty and work.

That is why the Ultra Trail Serra de Montsant remains a reference in the Catalan autumn. It does not need grandiloquence to justify its place. A natural park with character, a well-structured program, honest technical data, and a course that gives nothing away are enough. Anyone who stands on the start line knows they are entering terrain where time, stone, and effort management rule almost equally.
