Serra set to host a demanding 42-kilometre mountain race in 2027

Plan your race pace

The next edition of the Marató de la Calderona is scheduled for Sunday, February 28, 2027, in Serra, in Valencia province. Available information describes a mountain marathon of about 42 kilometres, with nearly 2,450 metres of positive elevation gain across trails and forest tracks. The key point for anyone considering taking part is that the date and town have been identified, but several practical details have not yet been confirmed in the information reviewed.

Announced as the 12th edition, the race should not be confused with an urban road marathon: available listings place it on trail and mountain terrain, with a demanding profile and sections through Serra, Segart and Estivella. The start and finish are listed at Plaça de la Font in Serra, although the final route, start times, prices and registration process still need confirmation from the organisers.

A mountain marathon in the heart of the Calderona range

Serra sits within the Serra Calderona, a rugged area where tracks and mountain paths alternate between exposed stretches and more sheltered sections. That landscape changes the demands of a 42-kilometre race. The distance may resemble a conventional marathon, but the combination of elevation, uneven surfaces and sustained climbs means that the effort cannot be judged by distance alone.

Competitor listings describe a course passing through Serra, Segart and Estivella, with technical trails and forest tracks. They also point to about 2,450 metres of positive elevation gain. These figures help provide an initial sense of the challenge, but they are no substitute for an official profile: without an up-to-date map, it is unwise to treat the checkpoints, distribution of climbs or specific terrain conditions as final.

The race name and date place the event on the 2027 calendar, but confirmed information should be kept separate from details still to come. February 28, 2027, is the listed date; the start time, aid stations, cut-off times and rules, however, do not appear in the available data. The event is described as its 12th edition, though participants should check the organisers’ published race information for any changes.

What is known about the date, start and distances

The event is scheduled for the last Sunday of February 2027. Plaça de la Font is named as the start and finish location in Serra. That helps locate the centre of the event, but it does not establish where race bibs will be collected, which streets may be affected or where parking is recommended. The square is the location listed for the start and finish, not a guarantee that all event logistics will be based there.

Available listings do not fully agree on the range of distances. One refers to a 42-kilometre marathon, while another lists both a half marathon and a marathon. The shorter distance should therefore be checked against the official event information before arranging travel or beginning specific training. The longer race is described as approximately 42 kilometres, a standard marathon distance, though the exact mileage should be confirmed against the final course.

The reference information also does not provide the entry fee, opening or closing dates, participant limit, or medical and federation requirements. It is not possible to give a price or say that entries are available. Registration should be checked directly through official channels once the 2027 terms are published, including the rules on transfers, withdrawals and refunds.

A course that calls for careful reading of the terrain

In a mountain race, two courses with the same distance can pose very different challenges. Elevation gain, the steepness of climbs, the length of descents and the balance between tracks and trails all matter. The approximate figure of 2,450 metres of climbing places this event in a demanding range for a marathon. Each ascent takes time and energy; every descent calls for muscular control and attention, particularly when the ground is loose or wet.

References to technical trails suggest that not every section will allow a steady pace. On narrow, rocky or uneven stretches, moving faster is not always more efficient: stable footing and careful line choice can reduce the risk of stumbling and fatigue. Forest tracks may allow a more fluid stride, although sustained gradients still raise the effort. Road-marathon pace is not a direct guide to estimating a finish time.

Available descriptions say the route crosses several municipal areas, but no official map or verifiable elevation profile has been provided. That makes precise calculations for pace, fuelling strategy or equipment difficult. Until complete information is available, it is more sensible to treat the distance and elevation as a general guide rather than a final course profile. The official route will be essential to understanding the true character of the day.

Preparing for 42 kilometres and the climbing

Preparing for a mountain marathon means combining endurance with adaptation to the terrain. Long runs help the body get used to hours of movement, while sessions on hilly paths develop specific strength and coordination. Simply adding flat kilometres is not enough: climbs demand different mechanics, while descents repeatedly load the quadriceps and ankles. Consistent training matters more than one exceptionally hard session.

Runners with mountain experience can use progressively harder routes to get used to elevation and practise switching between purposeful hiking and running. On steep slopes, brisk walking can be more economical than forcing a slow run. General strength work, adapted to each runner, may help with climbing and descending, but training loads should increase gradually and allow time for recovery.

The February date leaves months to prepare, although an appropriate plan depends on each runner’s experience, health and recent training. A mountain marathon with substantial elevation is not a suitable first long race for everyone. People with a history of injury, medical conditions or questions about how they tolerate exertion should seek individual medical guidance from qualified professionals. Preparation should suit the person, not just the calendar, with adequate rest and a gradual reduction in training before race day.

Equipment and race strategy for mountain running

Footwear should be chosen for the actual course surface, not simply because the event is called a marathon. Trail shoes may provide grip and stability on uneven paths, but the required traction depends on the terrain and weather. Without a detailed route, it is impossible to recommend a specific model. The sensible approach is to train in the shoes planned for race day and avoid wearing a new pair for the first time during the event. Comfort and support tested on similar routes come first.

Clothing also depends on the forecast and exposure to wind, rain or temperature changes. Conditions in late February can differ between lower areas and higher ground, but a reliable forecast for race day is not available this far ahead. The organisers will need to specify any mandatory equipment. Until then, decisions about a windproof layer, extra clothing or safety items should be treated as general planning, not as confirmed event rules.

An effort strategy should account for the full distance and elevation, with a controlled start and attention to how the body feels during the early climbs. Eating and drinking regularly is usually easier if practised during long training sessions. It is unwise to try unfamiliar products, quantities or pacing on race day. Race fuelling should be tested beforehand and adapted to individual needs; people with specific medical conditions should follow professional advice.

Registration and details still to be confirmed

The reference information does not clearly identify the organising body or provide a verifiable official domain. Some listings advise runners to check the official website, but do not give a specific address. For that reason, it is not possible to include a reliable link, confirm that registration is open or state prices and rules. Caution is especially important for future events: a calendar listing can help identify a race, but it may not contain the latest terms.

Before paying an entry fee, runners should check that the page belongs to the organisers or an authorised platform and that it sets out the date, distances, rules and financial terms. It is also worth checking whether the entry includes insurance, what documents are required and how cancellations are handled. These details are not confirmed in the information available, so they should not be assumed from partial listings.

The same caution applies to the course, schedule and services during the race. In a mountain event, knowing the locations of aid stations and cut-off times is not a minor detail: it affects pacing and the level of self-sufficiency required. The official information should also clarify whether a half marathon will be offered, which categories are included and whether age restrictions apply. Until those details are published, listings should be treated as an initial reference rather than a set of rules.

Planning the journey to Serra

Serra is the host town, and Plaça de la Font is listed as the central event location. Visitors from elsewhere will need to confirm the precise address, access arrangements and any traffic restrictions set by the organisers or the town council. No parking plan or event-specific public transport service has been provided, so it is better not to assume there will be spaces beside the start or a special shuttle.

Bib collection and access times may affect travel plans, particularly for people arriving on race morning. Since those times are not available, booking accommodation or calculating an arrival time based on invented details would not be useful. Once the participant guide is published, runners should check the collection location and time slots, traffic closures and designated parking areas. Travel plans should follow current instructions, not unconfirmed assumptions based on earlier editions.

It is also worth bearing in mind that a mountain race can mean a long stay in the area, even for runners who finish within the published cut-offs. Participants and supporters may need to agree on meeting points without obstructing the course. If the organisers publish travel advice or restricted-access areas, those instructions take precedence over informal plans. A start in a central square alone does not reveal how the event will operate.

Safety, conditions and recovery

Uneven ground and long descents make safety depend on both preparation and attention during the race. Keeping speed under control on technical sections, leaving room to avoid other runners and not pushing through signs of exhaustion are sensible practices in any mountain event. The rules and instructions from race officials should take precedence, particularly if weather conditions change or an incident affects the course.

The organisers have not yet detailed the medical provision, assistance points, communications coverage or withdrawal procedures in the available information. Those details matter in a race of this distance and elevation. Runners with a medical condition, taking medication or returning from a recent injury should discuss participation with health professionals and check the requirements eventually set out in the event information.

Recovery after a marathon involving climbs and descents may take longer than after a flat race of similar duration. Drinking to thirst, eating and resting all form part of a gradual return to activity; severe pain, dizziness or symptoms that do not settle warrant medical attention. Recovery does not end at the finish line, and its duration depends on the effort and each runner’s condition.

A date to note, with final rules still to come

The 2027 edition has a specific date and town, along with an initial description of a demanding mountain day: about 42 kilometres, roughly 2,450 metres of climbing and a route on paths in the Calderona range. According to the available information, Plaça de la Font in Serra is the start and finish location. That is enough to recognise the event’s broad profile, but not to finalise travel plans or make registration decisions.

Key participation details remain outstanding: the final map, whether a half-marathon distance will be offered, schedules, prices, aid stations, cut-off times and the official registration channel. Confirmation of those elements will make it possible to assess the challenge accurately and distinguish actual conditions from preliminary descriptions. Until then, February 28, 2027, and the event’s mountain character are the central reference points, with operational details subject to official publication.
