Ágreda’s 2026 San Silvestre: date, schedule and fees

Plan your race pace

Ágreda will host a new edition of its winter trail San Silvestre on Saturday, Dec. 26, 2026, with the start scheduled for 10 a.m. The event includes a trail race, junior and children’s races, as well as a walking option; the published fee for the main race is 20 euros, while each of the other three options costs 10 euros.

Registration is listed as open and closes on Dec. 21 at 11 p.m. The event is organized by NEVEROS VERTICAL AGREDA, with registrations handled by CARSO EVENTOS through RockTheSport. The available information confirms the date, time and prices, but does not specify the distance, course or exact starting point, details that should be checked in the rules before traveling.

Race date, time and location

The race is scheduled for Saturday, Dec. 26, 2026, at 10 a.m. in Ágreda, a municipality in Soria province, in Castilla y León. The registration listing identifies the town and postal code 42100, but does not name a square, street or venue as the start location. As a result, it is not possible to identify a more precise meeting point with confidence.

The date falls in the middle of winter and two days after Christmas. That timing gives the event a different feel from a San Silvestre held on Dec. 31: the Ágreda race takes place earlier, during the final holiday weekend of the year. The morning start puts the event at the beginning of the day, although the available information does not say how long each option will last or whether they all start together.

The reference information does not provide a full schedule covering bib pickup, category start times, finish-line services or possible traffic restrictions. It also does not confirm whether the start and finish will be at the same location. When planning a trip, the difference between knowing the municipality and knowing the exact meeting point matters: the former is confirmed; the latter is not. The rules document is identified as Reglamento_II_San_Silvestre_Trail_2026, but its contents are not set out in the listing consulted.

Published race options and fees

The event offers four options: San Silvestre Trail, San Silvestre Junior, San Silvestre Kids and Marcha Senderista. The trail option costs 20 euros; the other three each have a fee of 10 euros. These are the published prices for the 2026 edition, including taxes according to the registration listing, not estimates based on other races.

The names distinguish a trail race, two events aimed at children or young people, and a walking alternative. However, the labels alone do not establish distances, minimum ages, categories, elevation gain or technical level. Those details can change from one edition to another and should be checked in the rules. In particular, the reference information does not state an official distance, so the event cannot be reliably classified as a 5K, 10K, half-marathon or another length.

The walking option broadens the event to include people who would rather explore the area on foot than enter the trail race. The identical 10-euro fees for Junior, Kids and the walking event do not, by themselves, reveal what each entry includes; the source does not specify services, insurance, aid stations, a T-shirt or a participant gift. The prudent approach is to treat the listed amounts as entry fees and not assume that they include items that are not expressly detailed.

Registration and deadlines

Registration opened on Sept. 17, 2026, at 9 a.m. and closes on Dec. 21 at 11 p.m. The listing consulted says registration is open. That places the deadline five days before the event, although the announcement does not mention an extension, a participant cap or an earlier sellout date. The stated deadline is Dec. 21, not race day.

Registration is processed through RockTheSport and is listed as managed by CARSO EVENTOS. NEVEROS VERTICAL AGREDA is identified as the organizer, a useful distinction if questions arise: the platform handles registration, while the organizing group is the point of reference for sporting and logistical information. The listing includes contact options for payment issues, registration details, receipts, changes and general questions, but the extract does not provide a specific phone number or email address.

Before completing registration, check that the selected option is correct and that the displayed fee matches it. In events with separate categories, a children’s entry is not the same as a place in the main race, and the fee does not reveal age or participation requirements. It is also sensible to keep the receipt and verify the personal details entered. The source says registration remains open, but does not provide information about refunds, transfers or the cancellation policy; those conditions depend on the organizer’s and platform’s published rules.

What is known about the course and what remains unconfirmed

The event name and listed category identify the main race as a trail event, meaning a race planned away from conventional paved roads. The listing also includes a walking option, but describes neither route. It provides no distance, total elevation gain, surface type, lap count, checkpoints or aid-station locations. Any detailed account of a specific course would therefore be speculative. The trail category is confirmed; the course’s technical features are not.

The lack of an official distance also makes it impossible to compare the effort with other mountain races or estimate how long it might take to complete. A short, steep course demands different preparation from a longer, gradual one; the word trail does not resolve that difference. The same applies to difficulty: without details about elevation, surface and obstacles, the race cannot be described as suitable for beginners or assigned a particular level.

The rules document named in the listing is the place likely to set out participation conditions and race rules, but the available information does not reproduce its sections. Before the event, it is worth checking for distances by category, age requirements, recommended or mandatory gear, bib pickup arrangements and safety rules. Until those details are confirmed, the only accurate description of the course is that it is a trail event in Ágreda.

A winter mountain event

The calendar makes this a distinctly winter event. At the end of December, daylight is limited and outdoor conditions can change quickly, particularly on open routes. That does not establish what the weather will be like in Ágreda on race day, but it explains why the forecast and clothing choices may affect the experience. No confirmed weather forecast for that date appears in the reference information.

In a mountain race, cold is not the only factor to consider. Wind, damp conditions or a wet surface can alter perceived temperature and footwear grip. The right response depends on the actual course, which has not yet been described, and on the duration of each option. Participants should adjust their preparation to the official information as it becomes available, without assuming the route will be technical, muddy or snow-covered simply because the event is held in winter.

The start is scheduled for 10 a.m., avoiding a dawn start, although times for the children’s categories and walking option are not known. Anyone traveling from another town should leave enough time to find the start area rather than relying on a generic address. The municipality is confirmed, but the exact gathering point is not included in the information provided; that detail could affect parking and the time needed to collect a bib.

An event for different kinds of participants

The combination of Trail, Junior, Kids and Marcha Senderista suggests an event designed for different participants, from trail runners to people who prefer walking. That variety is one of the clearest features of the event: it is not limited to a single race and offers alternatives at different prices. Even so, the labels do not establish which ages can take part or whether youth categories are divided by age group. Age requirements are not included in the available information.

For families, that distinction matters. Kids and Junior events may have their own schedules, distances and requirements, and should not be assumed to start alongside the main race. The listing gives their names and fees, but does not describe adult supervision, permission forms, participation rules or awards. Those points should be clarified in the rules or in information from the organizer before registering.

The walking event, meanwhile, offers an option for people who want to take part without competing in the trail race. The source does not say whether it shares the runners’ route, has a maximum pace or allows trekking poles. The difference between walking on a shared course and following a separate route can affect both logistics and equipment. Until the course is published, what can be verified is that the walking event is a separate option and costs 10 euros.

Event organization and documentation

NEVEROS VERTICAL AGREDA is identified as the event organizer. Registration, meanwhile, is managed by CARSO EVENTOS through RockTheSport. Distinguishing those roles helps clarify where different questions belong: registration issues can go through the registration channel, while questions about the course, schedules and rules are for the organizers. The listing identifies all three parties and their general roles.

The documents associated with the event include the rules for the second edition. That file matters because it may answer questions missing from the public summary, from participation requirements to safety rules and the complaints process. The reference provided does not reproduce the document, so it cannot confirm any specific clause. It also does not mention race services, medical support, a bag drop or showers; their availability should not be assumed.

Registration platforms generally display the terms in force when payment is completed, but the available summary does not detail extra charges or change policies. For that reason, the advertised fee should be read as the published amount for each option, without adding or subtracting charges that are not stated. The organizer and registration manager are identified, but the reference information does not provide a separate official event website apart from the registration system.

How to read the confirmed information

The most reliable details about the event are specific: date, time, town, options, prices, organizer and registration window. By contrast, the listing does not confirm distance, elevation profile, course or exact start location. Separating published facts from outstanding details prevents an appealing description from becoming a promise the event has not made. For planning, operational details should be checked in the rules and official updates.

It is also worth reading the categories carefully and not extrapolating from other San Silvestre races or previous editions. A similar name does not guarantee the same course, distances or services. The 2026 listing has different fees and four options, but that does not justify attributing routes or conditions not stated in it. Accuracy matters especially when planning travel or registering children.

The available number of places is not specified. The open-registration status means the source does not list registration as closed, but it does not prove that places are unlimited or guarantee that registration will remain available until the deadline if a possible cap is reached. The listing sets the administrative close at 11 p.m. on Dec. 21 and the race on Dec. 26. They are separate milestones, and both are confirmed.

Ágreda heads into the year’s end on the trails

The event combines a trail start with alternatives for young people, children and walkers, and places the race on a holiday date other than the final day of the year. Dec. 26 at 10 a.m. is the key detail for planning the day; the fees, 20 euros for the trail race and 10 euros for the other options, complete the basic registration information. The event is confirmed for Ágreda, Soria, and registration is open until Dec. 21.

The sporting challenge will depend largely on details not yet shown in the summary listing: distance, elevation, terrain and start times by category. Without them, there is no basis for comparing difficulty or describing the course scenery. What can be said is that the organizers have planned several ways to take part in trail running and walking on a winter morning. Informational caution does not make the event less appealing; it simply separates facts from assumptions.

The 2026 edition has a confirmed date and prices, but the full experience will only become clear when the course and specific rules are available. For potential participants, those details matter as much as the race bib: they indicate the expected effort, how to prepare and where to go. For now, Ágreda’s San Silvestre has a confirmed date and several participation options, with some logistical details still to be published.
