Siero trail race routes and schedule for 2026

Plan your race pace

The fourth Siero Trail will take place on Sunday, November 8, 2026, in Pola de Siero, Asturias, with mountain routes, a relay option and a walking category. The main distance covers 25 kilometres with 1,050 metres of positive elevation gain; the short trail is 11.5 kilometres with 300 metres of climbing, while the walkers’ route is 8.5 kilometres. Published information also sets the event’s general start at 9:30 a.m. and lists an entry deadline of November 2.

The event brings together options with different levels of challenge, although the available details do not yet include the full route, segment-by-segment elevation profiles or individual start times. That distinction matters: distance and elevation offer an initial sense of effort, but they do not replace the official track or elevation profile. Anyone planning to take part should separate confirmed information from details that have not yet been specified and check the organizers’ instructions before race day.

The November event in Pola de Siero

The event is scheduled for Sunday, November 8, 2026, in Pola de Siero, an Asturian municipality listed as the venue. Registration information gives the day’s general window as 9:30 a.m. to 3 p.m.; this is the published event schedule, not necessarily the duration of each race. The exact start time for each category should be confirmed in the updated program, especially for relay teams and participants travelling from elsewhere.

Bib pickup is scheduled at the Plaza Cubierta in Pola de Siero. Participants can collect their race pack on Saturday, November 7, between 6 p.m. and 8 p.m., or on Sunday between 8:30 a.m. and 9:45 a.m. A national ID card is required to collect the pack. The organizers also set specific requirements for anyone picking up another participant’s bib or a minor’s bib, so visitors should bring the relevant documents rather than assume that arriving at the venue is enough.

The program also lists a performance by Mago Pelayo at 6:30 p.m. on Saturday. On race morning, a bus for the relay category is scheduled to run between 9 and 9:15 a.m. This is an important logistical detail: relay runners should account for the transfer and arrive within the stated window, without assuming that the bus schedule is the same as the race start time.

The available information does not identify the exact start and finish address or confirm whether the Plaza Cubierta also serves as the start area. The square is confirmed as the bib pickup location, but that fact alone does not establish any other use. Individual start times by distance are also not yet specified. Until those details are published, it is safer to treat 9:30 a.m. as the general start of the event, not as a confirmed start time for every race.

Three formats for different mountain-running paces

The longest category covers 25 kilometres with 1,050 metres of positive elevation gain, a combination that calls for saving energy on climbs and managing pace carefully. The total ascent is a useful guide to uphill effort, but it does not show how that effort is distributed. One sustained climb, a series of short rises and a more gradual profile can make the same figure feel very different; the official elevation profile and track will be needed to assess the challenge more precisely.

The short race covers 11.5 kilometres with 300 metres of positive elevation gain. Its shorter distance and lower ascent make it a more compact option within the program, but that does not automatically make it easy. Ground conditions, the gradient of individual sections and the placement of climbs all affect effort. The event information does not specify the surface or detailed profile here, so it is not possible to say what proportion runs on tracks, paths or other terrain.

The walkers’ option covers 8.5 kilometres. It is the shortest announced distance and is intended as a walking category, distinct from the two races. The information provided does not state its elevation gain, permitted pace or specific conditions. Anyone considering this option should wait for the full rules and schedule rather than infer its profile from the 300 metres of climbing listed for the short race, which is a separate category.

The event also offers a relay format with two legs of 13 and 12 kilometres. Together they add up to 25 kilometres, but taking part as a team differs from running individually: it involves coordinating the handoff and accounting for the announced bus transfer. Registration information lists a fee of 17 euros for this option. Teams should still check the rules for handoff arrangements, where each runner should wait and what instructions apply to completing the relay.

Elevation, routes and what the published information leaves out

The published figures offer a clear basis for comparing categories, but they are not a complete map of the race. For the long distance, 1,050 metres of positive elevation indicate a route with a substantial climbing component; for the short race, 300 metres describe a more moderate total ascent. However, the available information does not give the highest point, checkpoints, aid stations or a kilometre-by-kilometre breakdown. Those details could change how participants assess the challenge.

The event information refers to routes, tracks and elevation profiles as race materials, but the details available here do not include the files or profile images. It is therefore not possible to describe specific paths, settlements along the route, technical sections or views of the area with confidence. Adding such details without evidence would present an unverified route as confirmed. The fact that the event is in Asturias is not enough to establish the precise mountain terrain or surface.

Before travelling, participants should check that the track corresponds to the 2026 edition and their chosen category. When an event has multiple routes, a general profile can be mistaken for the profile of another distance; checkpoints may also change for organizational or safety reasons. The current rules and the specific map for each category will be the key documents, setting out participation conditions and race instructions once the organizers publish them.

Positive elevation gain should not be confused with the difference between the highest and lowest points. It is the cumulative total of the route’s climbs, while the elevation profile may include descents and short rises that a single figure cannot show. Two 25-kilometre races can demand different efforts even when their distances match: gradients, surfaces, weather and the placement of climbs all matter. November conditions may also affect how the terrain feels, although they do not make it possible to predict the weather on race day.

Registration, fees and required documents

The published registration period runs from June 30 at noon through November 2, 2026, at 11:59 p.m. That deadline falls several days before the event on Sunday, November 8. Listed fees, including taxes, are 25 euros for the 25-kilometre race, 16 euros for the short trail, 10 euros for walkers and 17 euros per participant in the relay. A separate activity called Crece Trail Siero is also listed at 10 euros.

The amounts reflect the registration information currently available and may be subject to event conditions. For the relay, the listing describes the fee as an individual price, so teams should verify how payment applies to the number of participants. Crece Trail Siero appears in the fee table, but its distance, minimum age, format and schedule are not described here. Its features should not be assumed without checking the full event documents.

A national ID card is required to collect a bib. The program also mentions a FEMPA or FEDME licence, authorization when someone else collects the race pack and paperwork for minors. The excerpt does not explain exactly when each licence is required or reproduce the full authorization forms. The rules for this edition should be checked, particularly when registering a minor or arranging for another person to collect a bib.

The pickup schedule allows participants to collect their race pack on the previous evening or on race morning, although Sunday pickup ends at 9:45 a.m. That may be a tight window for late arrivals who still need to resolve paperwork or travel to the start. The pickup location is identified as Plaza Cubierta in Pola de Siero; the start location is not specified in the information available. Keeping those two references separate prevents participants from planning around an address listed only for bib collection.

Reading the schedule and planning race day

The program for Saturday, November 7, schedules race-pack pickup from 6 p.m. to 8 p.m. and the performance at 6:30 p.m. Pickup opens again on Sunday, November 8, from 8:30 to 9:45 a.m. The relay bus is scheduled during the same morning, between 9 and 9:15 a.m. These timings help organize the day, but they do not replace the category-specific start times, which are not broken out in the information reviewed.

For long-distance participants, knowing the total ascent is a first step in assessing the effort, not enough to decide on pace or equipment. The 25-kilometre distance and 1,050 metres of climbing make it important to review the official profile once available and confirm the route conditions in the rules. Trail surfaces can vary within the same event, so footwear and clothing choices depend on the published route and weather forecast, not merely on the category name.

For the short race, 11.5 kilometres and 300 metres of climbing provide a more useful reference than a generic difficulty label. Even so, a sustainable pace depends on each runner’s experience and the distribution of the climbs. The walkers’ category has a confirmed distance of 8.5 kilometres but no detailed elevation figure in the available information. Comparing the three options by distance alone would overlook important differences in format and effort.

Relay teams need additional planning because the program includes a bus transfer. They should confirm the logistics for the 13- and 12-kilometre legs, each runner’s meeting point and the handoff procedure. The published fee is individual, and teams should not assume that it automatically represents the total cost. Checking these details before registering can prevent confusion on race day, when bib pickup and transfers may leave less time to spare.

An edition whose remaining details still need confirmation

The available information confirms the main elements of the event: date, town, distances, key elevation figures, fees and part of the schedule. It also distinguishes the individual 25-kilometre race, short trail, 8.5-kilometre walk and relay. This is a useful starting point for choosing a format, but it does not provide enough information to describe the exact route or reconstruct every operational detail.

Participants still need to check the start times for each category, the precise start and finish locations, downloadable tracks, complete profiles, aid stations and detailed rules. Information about Crece Trail Siero and relay transport conditions also remains to be confirmed. Keeping pending details separate from published facts prevents estimates from being mistaken for certainty, especially in a race where the route determines much of the effort.

The November 8 date places the event in the middle of autumn, when daylight and ground conditions can affect the racing experience. That does not allow anyone to predict rain, mud or specific temperatures, but it does underline the value of checking the forecast close to race day and following official instructions. The organizers are the source for any changes to the schedule, route or requirements, while the registration information sets out the published fees and deadline.

Based on the confirmed details, the event offers a broad range of formats: a long route with 1,050 metres of climbing, an 11.5-kilometre short option, an 8.5-kilometre walk and a relay alternative. The differences are not limited to distance; elevation, participation format and logistics also vary. The map and rules will turn these figures into a more precise picture of the day, from the start to the finish in Pola de Siero.
