Bizkaia Kopa Trail 2026: dates, distances and stages

Plan your race pace

The 2026 edition of the Bizkaia Kopa Trail brings together six mountain events across municipalities in Bizkaia, with options to run or hike. The information provided places one event in Lezama on Nov. 21; calendars consulted also mention stages in Arrieta and Larrabetzu, so each race needs to be distinguished from the league as a whole.

The format combines competitive 10- and 20-kilometer races with noncompetitive hikes over the same distances. Some stages also advertise txakurkros, a discipline in which runners take part with their dogs. Not every option is necessarily available at every venue, and schedules, courses, prices and registration status depend on the specific event.

A mountain league with six events

BKT operates as a popular circuit, not as a single race with one course. Its sixth edition consists of six stages spread throughout the year, in towns across Bizkaia. That structure lets people enter one event or follow several races and compete for the overall standings, subject to the rules and categories for each edition.

The 2026 calendar reflects the variety of venues. Available information identifies Arrieta as the fourth stage, scheduled for Oct. 10, while other listings place races in Larrabetzu and Zamudio in November and December. The additional details for this event identify Lezama for Nov. 21. These are references to different events or listings that do not match one another; they should not be combined into a single definitive course or schedule without checking the organization’s specific announcement.

This distinction also matters when looking for registration and results. One portal may show a venue-specific listing, another the league calendar, and a third a previous edition. The shared name helps identify the circuit, but the town and date identify each individual event. For the November race, the supplied information gives Lezama and Nov. 21, 2026; details about its course and conditions are not complete in the available references.

Race and hike: two ways to cover the mountain

The most common offering includes two competitive distances, 10 and 20 kilometers, and two hiking options over the same distances. The difference is not just pace: races count toward the league standings, while the hikes are designed as noncompetitive events. Participants can choose whether to measure their performance or enjoy the route on foot without competing for a placing.

For the competitive events, information about the Arrieta race mentions individual and team standings, as well as men’s, women’s and veterans’ categories. The exact categories and scoring system may vary or be governed by specific regulations. The same distance therefore does not necessarily mean that every stage has identical participation and ranking rules.

The 10-kilometer option often appeals to people trying trail running or looking for a shorter day; 20 kilometers demands more time and careful pace management. That difference is especially noticeable in the mountains, where elevation, mud and uneven ground can make two routes of the same length feel very different. Distance alone cannot determine difficulty: the elevation gain, surface and time limits also matter.

What is known about the venues and routes

Reference information describes the Arrieta stage on Oct. 10 as an event in a natural setting, starting at 9 a.m. and with a 2 p.m. course cutoff. It also says that venue offers 10- and 20-kilometer races and hikes. These details are useful for that specific event, but they should not automatically be applied to Lezama or any other stage in the circuit.

The November listing does not provide a detailed route, a start or finish address, or a start time. It also gives no elevation profile, aid-station information or terrain conditions. The absence of those details does not mean the event has none; it means they cannot be confirmed from the available information. In a mountain race, the profile and surface are essential to judging the effort and choosing equipment.

Bizkaia’s landscape includes green hills, tracks, trails and paths that can change considerably in wet weather. A route that looks straightforward on a map may include narrow or slippery sections, while a broad track allows a steady pace. Without an official profile, it would be unwise to describe a route as easy or technical. Difficulty depends on the course published for each venue, not on the circuit’s general distance options.

Txakurkros expands the format

One discipline associated with the league is txakurkros, a race in which a person runs connected to a dog with a leash system. The Arrieta event reference includes it among the competitive categories that count toward the standings. It differs from individual trail running because runners must coordinate their pace and pay attention to both the terrain and the animal’s well-being. Its presence needs to be confirmed for each stage; the available information does not establish that it is part of the Lezama event.

In this discipline, safety depends on consideration for other participants, the dog’s fitness and the organizer’s specific rules. The terrain, temperature and duration also matter; a long climb or abrasive surface may affect the animal differently from the person. Regulations often cover details such as connecting equipment and start conditions, but the specific rules are not detailed in the information reviewed.

The range of formats helps explain the circuit’s popular character. Alongside those chasing a time or points in the standings are walkers and teams approaching the mountains at a different intensity. The combination of racing, hiking and, at some events, running with a dog makes each venue broader than a conventional competition. The experience changes with the format, even when participants share the same mountain setting and local event.

Registration, deadlines and prices

For the Arrieta event, published information sets the registration deadline at 3 p.m. on Oct. 8, 2026. It also says registrations made during race week do not include a gift. That deadline applies to the Oct. 10 event and does not confirm registration dates for the November race. Registration periods may open and close independently for each town.

The references do not provide a reliable price for the Lezama event. They also do not establish whether races, hikes and txakurkros have different fees, or whether late registration costs more. The key is to make sure the registration page clearly states the venue, distance and chosen format. A general calendar is no substitute for the registration listing, which should show the fee, deadline and applicable conditions.

For the Arrieta stage, an registration portal shows entries as closed, which is consistent with its listed deadline having passed. That status should not be confused with other events in the season. For Lezama, the supplied information confirms a date and town, but not the status of available places. Registration cannot be described as open, sold out or closed without a specific statement from the organizer or the platform handling entries.

How to read the dates shown on race calendars

Differences between race listings are common in circuits with multiple stages: one date may refer to Arrieta, another to Larrabetzu and another to the season finale. Here, reference material links Oct. 10 with Arrieta and places Larrabetzu on Nov. 21; the additional information identifies Lezama for that same date. The discrepancy over the venue is not resolved by the available material, so it should not be presented as though all sources agree.

The safest way to read the information is to separate confirmed details from those still pending. For this article, the date and town explicitly provided are Nov. 21, 2026, and Lezama. The 10- and 20-kilometer distances describe the circuit’s general format and appear in information about other stages, but there is no complete Lezama program confirming every category. Information specific to the event takes precedence over a general description of the league.

It is also worth checking the year and edition when looking up results or regulations. A page retaining details from previous seasons may show routes, prices or schedules that no longer apply. In a league now in its sixth edition, the circuit name remains, but venues and event-day arrangements can change. The date, municipality and format should match on the same listing before anyone treats an entry as valid or plans a trip.

What participants can expect on the day

A trail event in a small town can change the local rhythm for a few hours. The start area fills with runners in muddy shoes, hikers preparing their poles and companions keeping an eye on the schedule. With no published details about the Lezama program, it is not possible to specify the start location or public services, but the league format points to a morning centered on mountain activity and local participation.

Someone entering a competitive race approaches the course differently from someone signing up for a hike. In either case, the distance should be chosen according to experience and route characteristics, not just the number of kilometers. Mountain effort can last longer because of climbs and terrain; that is why 20 kilometers of trail running is not equivalent to 20 flat road kilometers.

For spectators, the variety of events means following a day that is not limited to one start. Races, hikes and possible team categories extend the activity and bring together different kinds of participants. That shared atmosphere is part of BKT’s appeal: it is a competition, but also an entry point to Bizkaia’s trails. The atmosphere depends on each town and its residents’ involvement, a quality that is hard to capture in a distance chart.

A season best understood one stage at a time

The 2026 season presents mountain running as a circuit rather than a single finish line. Its six events offer the chance to return to different towns, compare terrain and follow standings throughout the year. The references provide a date, start time and formats for Arrieta; for the November event, the supplied details identify Lezama on the 21st, although there is no complete listing confirming local schedules, route profile, fee and available formats.

The clearest way to read the calendar is to keep that distinction in view: the circuit offers 10- and 20-kilometer races and hikes, while each specific stage needs its own official information. This prevents the start time or cutoff for one venue being attributed to another. BKT 2026 combines competition with popular participation, but practical details are settled only when they are published for each town.

In a league spread across Bizkaia, the route is more than a line between start and finish; it also defines the character of each event. A damp trail, an open track or a long climb can completely change the effort and experience. The season invites participants to discover that variety, with each stage’s details kept clear. The date and town provide the bearings; the official profile shows what the mountain actually has in store.
