A 25 km trail with 1,800 metres of climbing in the Serralada Litoral

Plan your race pace

La Neorural returns to Santa Maria de Martorelles, in Barcelona, on Sunday, Dec. 13, 2026, with a 25-kilometre mountain course and close to 1,800 metres of elevation gain. The combination of distance, accumulated climbing and uneven ground makes this more than an introductory trail race: it calls for experience on mountain paths and the preparation to sustain the effort for several hours.

The route runs through the Serralada Litoral, linking dirt tracks, trails and mountain sections with places such as Castellruf, Castell de Sant Miquel and Turó de Galzeran. The available information confirms the date and the broad course profile, but does not give a start time, entry fee or exact start location. Those details can affect race-day planning and should be checked in the organizer’s official communications.

A short race by distance, a demanding one by effort

Twenty-five kilometres may seem moderate next to a mountain marathon, but distance alone does not explain what this route demands. With approximately 1,800 metres of elevation gain, it packs climbing into a relatively compact course: every ascent reduces speed, loads the muscles and requires more careful pacing than a flat race.

Elevation gain is the cumulative total of the climbs, not the difference between the starting and finishing elevations. So even if the finish is at roughly the same altitude as the start, the body may have climbed close to 1,800 vertical metres during the day. On a rolling course, descents are not a complete rest either. They require control, stability and attention to the ground, as well as eccentric muscle work, especially in the quadriceps and calves.

The relationship between distance and elevation helps explain the race’s character. It is not a course where runners can simply transfer their usual road pace to the mountains; finishing time will depend heavily on the profile, technique and ground conditions. A runner may move smoothly on the tracks and lose minutes on a rocky descent or a steep climb where walking is more efficient.

The Serralada Litoral terrain sets the pace

The course is set in the Serralada Litoral, a rugged area near Santa Maria de Martorelles and the Barcelona metropolitan area. The description of trails and dirt tracks points to a race far removed from continuous pavement. The surface may shift between compact sections and rougher ground, making every change in gradient a decision about pace and footing.

The course description highlights an intention to include plenty of narrow trail, or singletrack, as well as elevation. In these sections, passing space may be limited and the race becomes more tactical: keep a sensible gap, look a few metres ahead and avoid unnecessary surges to conserve energy. It is not only about running fast, but moving precisely when the path demands shorter strides.

Track sections may feel like a relief, although they do not always allow an immediate recovery. After a sustained climb, the heart rate will remain elevated and the legs will feel the effort. The shift between open ground and technical trail calls for adjusting your effort instead of chasing a uniform pace, a key difference from road races, where surfaces and cadence are generally more consistent.

Castellruf, Sant Miquel and the course’s ridges

The route information names Castellruf, Castell de Sant Miquel and Turó de Galzeran among the course landmarks. These places locate the race amid a succession of ridges and recognizable sites in the hills, suggesting a route that is not simply a loop on an easy circuit. The available description points to varied, rugged sections, although no detailed elevation profile is available to assign a specific distance or difficulty to each landmark.

The Teula, Sunyera and Dinamita springs are also mentioned along the route. As well as serving as geographical markers, they evoke the character of a race through mountain paths rather than a closed urban space. Without an official map in the information reviewed, it would be unwise to infer the exact order of passage or claim that all the springs will be used as aid stations.

These landmarks help picture the landscape, but the race’s appeal does not depend only on named places. What matters to runners is the continuity of the climbing, the surface and the room to manage their effort. A distinctive landmark can be a useful mental marker, but it is no substitute for studying the profile and reading the terrain at every turn.

A race better suited to experienced trail runners

Given its distance and elevation, the race appears aimed at people who already know the demands of trail running and are comfortable alternating between running and hiking in the mountains. That is not an official entry requirement, which is not included in the available information; rather, it describes the experience that can help runners enjoy the course safely without having to improvise on every climb.

For runners familiar with trails, 25 kilometres can be a demanding challenge or a benchmark session within a longer training build-up. But using it as preparation for an ultra does not make it an easy workout. Concentrated climbing can be tougher than a longer distance on runnable terrain, and the effect will depend on experience, fitness and intensity management.

Anyone new to mountain races should honestly assess their confidence on descents, their ability to stay active for an extended period and their response to sustained climbs. Road experience is a useful foundation, but it does not reproduce the ankle and hip work required by uneven trails. Training on elevation matters too: the strength needed to climb and the control required to descend are built through gradual exposure, not simply by adding flat kilometres.

Understanding elevation without treating it as an abstract number

The 1,800 metres of climbing are a useful reference, but they do not fully describe the difficulty. Two courses can have the same distance and elevation yet feel very different if one concentrates its climbs in a few long ascents while the other alternates short rises, technical descents and rolling ground. Gradient, surface and how effort is distributed all affect time and fatigue.

It is also worth distinguishing between elevation gain and total elevation change. The figure provided refers to accumulated climbing, not the combined total of ascents and descents. On a mountain course whose start and finish are at similar elevations, substantial descending is reasonable to expect, but the exact elevation loss is not specified in the reference information and should not be presented as confirmed.

Difficulty, therefore, cannot be reliably translated into a simple road-distance equivalent. Each runner’s time will depend on climbing pace, technical confidence and the conditions on the day. If the ground is wet or muddy, footing may change; if it is dry, loose stones may still require attention. These are possibilities in a natural setting, not a forecast for race day.

December adds variables to race day

The race is scheduled for Dec. 13, during meteorological winter. The date alone cannot predict rain, cold or trail conditions on the day. It does mean shorter daylight hours than in spring and summer, and conditions may vary between exposed areas and sheltered sections of the hills.

Weather can directly affect the mountain-running experience. Rain changes dirt paths, wind is more noticeable on ridgelines, and a cool start does not guarantee the same feeling after several hours of exertion. Suitable clothing and equipment depend on the rules and the forecast closer to race day; no official mandatory-equipment list is available here.

It is also important not to mistake a general course description for a complete technical guide. The available information does not include the start time, aid stations, checkpoints, cutoff time or a detailed elevation breakdown. These details matter when estimating the day’s duration, arranging transport and deciding what to carry, so they should be checked when final event information is published.

Preparation: strength, technique and patience on climbs

A course with this much accumulated climbing calls for preparation that combines endurance with mountain-specific work. Runs on hilly terrain help the body adapt to continual changes in gradient, while strength sessions can help runners tolerate both ascents and descents. Training load should increase gradually, particularly for anyone not used to linking long climbs.

Descending technique deserves as much attention as climbing ability. Rushing downhill without control can increase the risk of a stumble and fatigue the legs early; always descending too cautiously can also add considerable time. The goal is a stable stride, attentive footing and a position that allows a quick response to changes in the surface. In the mountains, conserving energy also means avoiding abrupt movements.

Pacing starts before the first hill. In a demanding race, setting off at the pace of a short event can take its toll while many metres of climbing still lie ahead. Running and hiking on the steepest slopes is not necessarily a sign of weakness; it can be an efficient way to contain effort and save capacity for the rest of the course. Experience helps runners recognize when to push and when to walk.

What is known and what still needs confirmation

The reference information provides three central facts: Santa Maria de Martorelles as the location, a 25-kilometre course and around 1,800 metres of elevation gain. It also places the route in the Serralada Litoral and names several landmarks and springs. The date of Dec. 13, 2026, is confirmed in the information provided, but confirming the date does not mean that all race-day details are available.

No entry fee, start time, exact start and finish address or official website link is listed. There is also no specific information about entry limits, categories, services, race rules or cancellation policy. It would be unwise to fill these gaps by comparing the event with other races or previous editions: prices and conditions can change from year to year.

The organizer’s published event information will be the definitive reference for planning participation. A map and elevation profile will show how the climbs are distributed; the rules will clarify entry conditions and equipment; and access details will help with travel arrangements. Until those are available, the course description gives a broad sense of the challenge but does not replace an official technical guide.

A mountain race that rewards reading the terrain

The event combines a distance manageable for mountain runners with enough climbing to make it a serious challenge. Its 25 kilometres should not be read as a fast, straightforward half-day outing: accumulated ascents, trails and potentially uneven ground mean that the time and energy required will depend on technique as much as fitness.

According to the available information, the race offers an intense way to explore the Serralada Litoral and its ridges, with landmarks such as Castellruf, Sant Miquel and Turó de Galzeran. For experienced trail runners, the appeal lies in the balance of distance, elevation and varied terrain. For those with less experience, the same combination is a reason to consider carefully whether their preparation matches the expected demands.

The calendar points to Dec. 13, 2026, but practical details still need confirmation. Until they are published, the clearest picture is a compact, technical trail with close to 1,800 metres of climbing: a day when progress will depend less on maintaining a fixed pace than on adapting to each section of mountain terrain.
