Picos de Europa ultra 2027: date, distances and registration

Plan your race pace

The 2027 edition of Ultra Trail Picos de Europa will take place on April 10 in Tama, in the Cantabrian municipality of Cillorigo de Liébana. The event announces three mountain courses covering 51, 31 and 21 kilometres, starting and finishing in the village. The ultra begins at 7 a.m.; the trail race and half-marathon option start at 9 a.m.

The announced registration period opens on September 1, 2026, at noon and closes on March 14, 2027, at 11:59 p.m. Critical Sport SL is listed as the organiser. The available information establishes the date, distances and start times, but does not include entry fees, participant limits or full regulations detailing mandatory equipment, checkpoint cut-offs or entry requirements.

The event puts Liébana on the spring trail running calendar with a programme combining endurance and mountain skills. These are not three interchangeable versions of the same experience: the announcement distinguishes an ultra requiring technical ability and experience, a demanding intermediate course and a technically more accessible option that still involves significant elevation change. That distinction matters more than the name given to each race.

The chosen Saturday provides a clear reference for planning the season, but it also makes it important to separate this event from other races held across the wider Picos de Europa region. Some calendar entries mix locations, distances or estimated dates. For this edition, the confirmed information is Tama on April 10, not a start in Caín or a June race in Asturias.

Geographical precision helps prevent another common misunderstanding. Tama is the village hosting the start and finish; Cillorigo de Liébana is its municipality. Both names may appear when searching for the race, booking accommodation or finding the event in a calendar. The specific starting location given for all three races is Tama bridge, although no coordinates or details of the finish-area setup have been supplied.

The main race offers 51 kilometres of mountain running. The organiser presents it as the flagship event and warns of demanding elevation change requiring technical ability and experience. Its distance exceeds that of a marathon, but mileage alone does not explain its difficulty: in a mountain ultra, sustained gradients, footing and the accumulated strain of several hours of effort also matter.

The 7 a.m. start puts ultra runners two hours ahead of the other fields. That information helps with planning the journey to the start, rest beforehand and a pre-race meal. However, it does not establish the time limit or prove that a headlamp is mandatory. Both points require the event-specific regulations rather than an assumption based on the clock.

Over 51 kilometres, moving efficiently at a slower pace can be as important as running comfortably. A sustained climb often changes both movement and pace; a technical descent may demand more attention than a fast section. The experience mentioned in the announcement should be understood as managing terrain and fatigue, rather than simply having completed a long distance on roads or straightforward paths.

Trail Picos de Europa offers 31 demanding kilometres, with elevation change and technical sections according to the organiser. It is a shorter alternative to the ultra, but it is not presented as an easy race. The combination of sustained effort and skill on the ground gives it a character of its own: fewer kilometres do not remove the muscular demands of the slopes or the need to concentrate on foot placement.

This race shares its 9 a.m. start with the half marathon. A common start time does not establish that both events follow the same opening kilometres, share aid stations or use identical checkpoints. Those details would need confirmation from course maps and race documentation. The published information establishes a shared start time, without describing how the routes divide after Tama bridge.

The third option is called Medio Maratón Picos de Europa and has a published distance of 21 kilometres. The name should not be confused with certification of a 21.0975-kilometre road half-marathon course. This is a mountain event whose length is given as a rounded figure. The organiser describes it as technically more accessible than the other two races, while noting that it still includes substantial accumulated elevation change.

That distinction prevents the 21-kilometre race from being presented as an automatic entry point for any runner. Someone used to urban half marathons may have sufficient endurance yet still need to adapt to descents, uneven footing and changes of pace. More accessible does not mean easy: the comparison is within this event, not against a flat race or every trail event of similar length.

Choosing among the three races therefore depends on more than weekly training volume. Recent mountain experience, muscular response on descents and the ability to keep making decisions when tired all count. For runners who usually train in the Valencian Community, training terrain matters as much as accumulated mileage: a long run on comfortable paths does not reproduce every demand of a technical race.

Other event listings give elevation figures of 3,900 metres of ascent for 51 kilometres, 2,000 for 31 and 1,000 for a race described there as 20 kilometres long. However, those references do not clearly identify the edition and differ from the 21 kilometres announced for 2027. They should not be treated as definitive figures for this event without documentation expressly linking them to this edition.

The distinction is not trivial. Elevation gain measures the total metres climbed along a course and helps indicate the effort involved, while horizontal distance tells another part of the story. Two 31-kilometre races can demand very different levels of effort. For this edition, the description establishes climbing and technical difficulty, but the supplied information does not specify an official elevation-gain figure for each course.

No detailed map, navigation file or list of route points is available either. It would therefore be inaccurate to assign this race climbs, gullies or well-known paths used by other Picos de Europa events. The regional landscape offers many possibilities, but the specific route remains undescribed in the available information. Sharing the name of a mountain range does not make two courses the same circuit.

GTPE in Benia de Onís, for example, is a separate event in Asturias with a different set of races. Its distances, prices, start times and requirements cannot fill the gaps in the Tama race information. This distinction is particularly important when looking for registration: they are different events, even though both refer to the Picos de Europa and appear close together in search results.

The same applies to calendars placing a similarly named event in Caín on April 24, 2027, with its date marked as estimated. That information does not alter the confirmed event in Liébana. The combination of location, organiser and distances provides a more reliable check than the title alone. Here, the reference is Critical Sport SL and Tama, alongside the 51-, 31- and 21-kilometre courses.

The announced registration window runs from September 2026 to March 2027. As of October 8, 2026, that period has begun, but a registration window does not establish entry availability in each race. The supplied information does not state capacity, remaining entries or a sell-out. Nor does it explain whether the planned closing date could be brought forward if the participant limit is reached.

Entry fees are another outstanding detail. The supplied information does not publish prices for the ultra, trail race or half marathon. It also gives no pricing stages, discounts or processing charges. Assigning amounts taken from another event would be misleading: no verifiable entry fee is available for this edition from the supplied data, and a registration cost cannot be inferred from distance or the appeal of the surroundings.

The contents of the entry package are not defined here either. There is no detail on which services the race number includes, how sports insurance is handled or whether affiliated and unaffiliated runners are treated differently. The same applies to refund and name-transfer conditions. Race numbers advertised on external platforms do not prove transfers are permitted or establish an administrative transfer fee for this event.

Race documentation will be essential for resolving those points and distinguishing advice from obligations. The available information does not establish a medical certificate, minimum age, documented previous experience or required sporting points. It also does not detail mandatory equipment. Missing information is not an exemption: a requirement absent from a short description could still appear in the final regulations.

Equipment for a mountain race calls for attention to grip, protection and comfort over a sustained effort. Footwear needs to suit the actual ground and conditions on the day, rather than simply carry a trail label. A sole that works well on a dry path may behave differently on wet rock. Here, testing equipment in training matters, without presenting any brand or model as a universal solution.

Clothing is also part of managing the effort. April in a mountain environment does not guarantee mild, settled conditions, even if the valley feels pleasant at the start. Rain, wind or temperature changes can affect comfort and safety. There is no valid race-day forecast so many months in advance; a forecast close to the date will be much more useful than any promise of favourable spring weather.

This weather uncertainty does not justify predicting snow on the course or claiming that the race reaches particular elevations, because those details have not been published. It does explain why equipment needs to be considered alongside the route and regulations. Responsible preparation combines specific information with room to adapt. Scenery does not replace assessment of conditions: an attractive mountain setting remains an environment where the weather can change.

The same applies to food and water. Aid-station locations, spacing and contents are not known, so calculating the required carrying capacity or claiming a particular setup complies with the rules would be premature. Fuelling depends on time spent running and individual tolerance. Before applying general figures to this event, runners need to know its supply points and the conditions established by the organiser.

Physical preparation, however, has a clear principle: it should resemble the expected effort. In the mountains, climbing combines endurance and strength; descents add muscular work that flat running does not reproduce in the same way. Efficient walking can also be part of racing. Across all three distances, progressive adaptation to slopes makes more sense than accumulating mileage without considering where and how it is run.

That does not turn the event into a single training prescription for everyone. A runner with years of trail experience and someone moving over from road running have different needs, even if both choose 21 kilometres. Recent experience is more useful than an old personal best when assessing the starting point. In the ultra, fatigue also changes technique: footing that feels natural early on can become less precise after hours of effort.

Logistics begin with the correct location. Tama belongs to Cillorigo de Liébana, in Cantabria, and the bridge announced as the start provides a reference for locating the event. No details have been supplied about parking, road closures, collective transport or access to the runners’ area. For those travelling from Valencia or Alicante, the journey is part of planning, but no official travel times or special services have been announced that can be assumed to exist.

Race-number collection times and instructions for the preceding day are also missing. That gap particularly affects the ultra, which starts at 7 a.m.: collecting a number the evening before is different from collecting it immediately before running. Accommodation and arrival plans need that information. Race-morning collection is not confirmed, so runners should not assume that the process will be available just before the start.

Liébana provides a setting that extends beyond the stopwatch. The announcement highlights the landscape, food and culture of the area, a combination that places the race within a broader visit to the region. However, that description does not establish that sightseeing, meals or activities are included in the entry. The destination’s appeal belongs to the event’s surroundings; services independently booked by participants are a separate matter.

A start and finish in Tama provide a common base for the three races, but do not justify describing a specific loop without a map. Nor do they establish spectator areas or accessible viewing points. In mountain races, a location visible on a map is not always easy to reach by road. Following participants around the course requires the organiser’s own guidance, particularly where trails and restricted access are involved.

Checkpoint cut-offs, overall time limits and withdrawal procedures also remain unpublished. They influence distance choice as much as elevation gain. A course may be physically manageable yet have checkpoints requiring a particular pace. The current information allows a broad comparison of the options, but not calculations of checkpoint margins or the assignment of a maximum duration to any of the three races.

With those limits clearly separated, the announcement does provide enough information to place the event in the season: Saturday, April 10, 2027, Tama bridge, 51 kilometres at 7 a.m. and 31- and 21-kilometre races at 9 a.m. The announced registration deadline is March 14. These are the published practical details that can be used without mixing this edition with fees or requirements from different events.

The Liébana event offers three ways into mountain running, not three steps every runner must climb. Choosing a shorter distance can reflect experience, current fitness or the time available to prepare. The ultra retains its appeal, but the right distance is not always longest. On demanding terrain, independence and skill deserve as much weight as sporting ambition.

The value of this edition lies in a specific programme and a confirmed date, with Tama bringing runners and the surrounding region together. The unpublished details will need to complete the picture before race day. For now, the most accurate account avoids embellishing the route or promising ease: 51, 31 and 21 kilometres to test endurance and technique in Liébana, each with its own demands and no confusion between spectacular scenery and straightforward effort.
