Trail Arroniz 2026: date, start time and distances

Plan your race pace

Arróniz will host the ninth edition of its mountain race on Saturday, November 7, 2026, with two options: 10 and 23 kilometres. The start is scheduled for 9:30 a.m. in the Navarrese town. The longer race has 1,300 metres of positive elevation gain, while the shorter one has 250, according to the information available for this edition.

Registration is listed as open, with the published window running from September 1 at 10:30 a.m. to October 26, 2026, at midnight. The entry fee has not been provided, nor has a full November programme been published here; earlier editions’ race-pack collection times and other activities should therefore not be treated as confirmed for 2026. The date, start time and distances are announced.

A mountain race with two distances

The event combines a 10-kilometre race with a 23-kilometre option, allowing runners to choose between a shorter course and a longer challenge. The long distance is listed with 1,300 metres of positive elevation gain, a figure that points to a demanding route, although it does not by itself describe the gradient of each climb or the type of terrain.

The shorter option has 250 metres of climbing and reduces both race duration and ascent. It is not necessarily a stroll: it remains a trail race, with changes in pace and footing that an off-road course can bring. Distance and elevation help compare the effort, but the experience will also depend on trail conditions and the weather.

Date, location and start time

The event is scheduled for Saturday, November 7, 2026, in Arróniz, a municipality in Navarre on the slopes of Montejurra. The announced start is at 9:30 a.m. The available information names the town but does not specify the exact start point for this edition, so the municipality should not be mistaken for a confirmed street address.

In the 2025 programme, both distances started at the sports centre. That provides context on how the day was organised then, but does not prove the same venue will be used again. The exact location and any schedule changes should be checked in the organisers’ updated information before travelling.

Registration and published deadline

The registration platform lists a start date of September 1, 2026, at 10:30 a.m., and a closing date of October 26 at midnight. The event listing shows registration as open. That published deadline marks the end of the regular registration period, although places could run out earlier if a limit is reached; no 2026 entry cap has been provided.

The available information does not include the entry fee, so no reliable price can be quoted and there is no basis for saying whether prices change by tier. It is also unclear whether the two distances have different fees. Before submitting an entry, runners should check the final amount and current rules in the official registration form, including any booking fees and cancellation terms, if applicable.

What is known about the long course

The 23-kilometre distance and 1,300 metres of accumulated climbing make the long race the most demanding option in the announced programme. Positive elevation adds together the route’s climbs; it does not mean there is one climb of that height, nor does it say how much descent the course includes. The length of the climbs, surface and distribution of elevation gain also shape the effort.

The reference information does not include a confirmed map, full elevation profile, aid stations or a cut-off time. It would therefore be unwise to assign a specific route around Montejurra or assume whether the course mainly uses tracks, footpaths or technical sections. The reliable figures so far are 23 kilometres and 1,300 metres of ascent; the rest requires the official 2026 route details.

The 10-kilometre alternative

The shorter distance covers 10 kilometres and has 250 metres of positive elevation gain, considerably less climbing than the long race. For runners seeking a first mountain-race experience or a shorter competition, it may be a more accessible option in terms of volume. That does not guarantee an easy course: a concentrated climb or uneven ground can still make it challenging.

The 10-kilometre label describes the length, not each runner’s finishing time or the route’s technical difficulty. Trail pace often changes with gradients and footing, and directly comparing a road-running time with a mountain result can be misleading. The 250 metres of elevation gain offer a useful reference, but the detailed profile is needed to see how the climbing is distributed.

Registration dates differ from one edition to another

The published 2026 registration window closes on October 26, while the previous edition’s listing gave a different deadline: October 31, 2025. The difference shows why information from past events should not simply be reused: deadlines can change even when a race is held annually. For the 2026 edition, the date on its own listing is the one to follow.

Knowing the final registration date does not answer every practical question. The participant limit, required documents and rules for changing distance or transferring a bib may also matter. Those details are not included in the available material. The listing for the ninth edition is the valid reference for administrative conditions, rather than notices published for earlier years.

Race-pack collection and programme: what remains unconfirmed

For 2025, race-pack collection was scheduled for Friday afternoon and Saturday morning, both at the sports centre. That edition’s programme also listed award ceremonies for both distances and a gathering for participants after the races. These details provide context on the event’s previous format, but they are not an official 2026 schedule.

The information for the new event does not yet specify race-pack collection times, the venue, award times or post-race activities. Anyone travelling from another town should wait for the updated programme, particularly when planning arrival. Presenting last year’s timetable as confirmed could lead to planning mistakes.

Arróniz and the landscape around Montejurra

Arróniz lies in the Tierra Estella district, in an area associated with the slopes of Montejurra. The town has just over a thousand residents, according to the description in the reference information, and olive groves are a prominent feature of the landscape. This connection between terrain and agriculture gives the setting a different character from an urban race.

The olive trees and village streets help place the event in a rural area, but they do not reveal the race route. An event held in the municipality may pass through different areas and need not visit the town centre’s most recognisable spots. The local setting provides context, while the official map must show where each distance runs.

A race organised from the local community

The event is organised by Club Deportivo Arroniz Kirol Taldea. Information for the 2026 edition also identifies the club as responsible, while the description of the previous edition mentions the collaboration of Arróniz Town Council. The available details do not set out each organisation’s specific role in the upcoming event.

The race’s name and its continuation into a ninth edition place it on the local calendar. The 2025 reference to 400 bibs applies to that edition and should not be taken as the confirmed capacity for 2026. The number of places for the new event has not been published, so the historical figure cannot be used to calculate current availability.

How to interpret elevation gain in a trail race

Positive elevation gain is the total number of metres climbed over a route. A 23-kilometre course with 1,300 metres of ascent can feel very different depending on how that climbing is arranged: short, steep ramps create a different challenge from long, gradual climbs. The elevation profile and surface complete the picture.

For the shorter race, 250 metres of elevation gain over 10 kilometres gives a lower ratio, but still does not describe the technical difficulty. Loose stones, mud or abrupt changes in gradient can affect balance and speed if they appear on the course. Until the 2026 profile is published, elevation gain is a general reference rather than a complete description.

General preparation for both distances

Choosing a distance should reflect a runner’s recent experience on mountain terrain, not just the number of kilometres usually covered on roads. The long course requires tolerating a longer effort and substantial climbing; the shorter one reduces volume but retains the demands of running off-road. A gradual build-up is generally more sensible than a sudden increase in training load.

Training can combine easy running, controlled uphill and downhill work, and strength exercises suited to the individual. Not every session needs to feel like a race: practising foot placement and staying stable on uneven ground also form part of preparation. Consistency and a manageable workload matter more than one exceptionally hard session, particularly for mountain running.

Equipment and safety on uneven terrain

Suitable footwear depends on the surface and weather, details that cannot yet be specified without knowing the route. Trail shoes usually offer more grip and protection than road shoes, but models differ on mud, rock and compact tracks. Fit and comfort matter just as much as the appearance of the outsole.

Conditions can change during a November morning, although the weather on race day cannot be predicted months in advance. Checking the forecast closer to the event and following the organisers’ guidance will help runners choose clothing and equipment. Safety also depends on following race instructions and adjusting pace to the terrain, not just on what is worn.

What to check before travelling

The announced 9:30 a.m. start helps frame the day, but does not answer every logistical question. The exact start point, race-pack collection deadline, parking options and any local traffic restrictions remain unconfirmed. For runners travelling from elsewhere, these details may matter as much as the distance they choose.

It is also worth checking whether the final programme keeps one shared start or gives separate instructions for each distance. The 2025 reference listed both races as starting at 9:30 a.m., but that information belongs to another edition. A final check of the time and location avoids relying on outdated details when planning the trip to Arróniz.

The 2026 edition in context

The 2026 event is the ninth edition and, according to the published information, retains two distances: 10 and 23 kilometres. The previous edition was the eighth and took place on November 8, 2025. Scheduling the next race for November 7, 2026, keeps it in the autumn calendar, though it does not mean every part of the programme will remain the same.

Past editions help show the event’s continuity and the kind of race day it has offered. However, courses, additional timings, services and capacity can change. The 2025 edition provides context, not a substitute for current information; in particular, the sports-centre programme should not be presented as confirmed for the following year.

A race for different kinds of runners

The two distances appeal to different profiles, although that does not mean one option is right for every level. The 10-kilometre race may suit runners wanting to try a shorter mountain event, while the 23 kilometres and 1,300 metres of climbing present a longer challenge. Previous experience on trails is a more useful guide than a single road-running time.

New trail runners can focus on downhill technique, effort control on climbs and reading the ground. Walking a steep climb is not necessarily a failure; it can be a sensible way to save energy. Each participant’s goal and experience should guide the choice of course, based on the actual profile once it is available.

The place of a small-town race on the calendar

Races in smaller towns often bring competition closer to the surrounding landscape and everyday community life. In Arróniz, olive groves and the proximity of Montejurra form part of that setting, although the exact route will determine what runners see. A local atmosphere does not reduce the challenge: a race can feel welcoming while still putting the terrain to the test.

The event’s continuation through nine editions also points to a lasting connection between sport and the local community. That history should be kept separate from the practical details of a particular year, which change and need fresh confirmation. The race’s appeal comes from both its setting and its challenge, two elements that complement rather than replace official route information.

What is confirmed and what is still pending for November

The central details are clear for now: the race takes place on Saturday, November 7, 2026, in Arróniz; the start is set for 9:30 a.m.; and the distances are 10 and 23 kilometres. The published elevation gains are 250 metres for the shorter route and 1,300 for the longer one, while registration is due to close on October 26. These details identify the event.

The entry fee, exact start point, course maps, aid stations, race-pack programme and participant limit remain to be clarified. Missing information does not invalidate the event, but it is a reason not to fill gaps with details from previous editions. Once the updated profile and programme are available, runners can assess the Arróniz challenge more precisely.

An autumn morning among trails and olive groves

The day will begin early for those travelling to the town and wanting time before the start. At 9:30 a.m., the two announced distances set off on a race that combines Arróniz’s rural surroundings with the demands of trail running. The autumn setting adds atmosphere, but actual conditions will depend on the weather that week.

The event brings together a shorter option and a more demanding mountain course, with enough information to compare their requirements while other details remain unpublished. That makes the ninth edition identifiable without turning unannounced details into certainties. The final route profile will complete the picture of the race before participants reach the start line.
