Jaca will host a new cross duathlon event in November 2026

Plan your race pace

The next edition of the Mayencos Cross Duathlon Trophy will take place on November 8, 2026, in Jaca, according to the information available. The date and town are confirmed, but no start time, course, distances, entry fee or registration period has yet been provided. Earlier editions offer useful context, but they do not establish what the 2026 event will look like.

The event is part of a sporting tradition connected to Club Pirineísta Mayencos and the Aragonese cross duathlon calendar. Recent editions have brought together races for children and adults, and in 2025 the elite event also hosted the Aragon Championships. The new date places the race in the heart of autumn, although the full programme must still be confirmed before its schedule, format or expected turnout can be described.

A confirmed date, with details still to come

The firm information for 2026 is Sunday, November 8, in Jaca. No start time or exact address has been supplied, so it is not yet possible to identify the transition area or finish line. It is also unconfirmed whether the day will include children’s races, open categories or an elite event with a regional title at stake.

A date announcement is not the same as a published race guide. In cross duathlon, the order and length of the segments, eligibility rules, categories and bike regulations all affect preparation and logistics. Until the organisers or federation publish those details, figures from previous editions should not be treated as the 2026 programme. The calendar date may be fixed before the technical information is ready.

Registration details and the fee are also unknown. There is no confirmed price or official registration link in the information available, so any figure or deadline would be speculation. For events of this kind, the rules usually clarify required documentation, federation licences and options for non-licensed athletes; those requirements cannot be anticipated here.

Mayencos’ place in the Aragonese calendar

The Mayencos Trophy is an established event in Jaca and has a long presence in Aragonese cross duathlon. Records from earlier editions describe an event organised by Club Pirineísta Mayencos, which has combined its main competition with activities for school-age participants. This link between federated sport and children’s participation helps explain why the day extends beyond the elite race.

The event has also been associated with the Aragonese Cross Duathlon Cup, a circuit that the Aragon Triathlon Federation presented in 2024 as six races spread across Aragon’s three provinces. That calendar listed Jaca on October 13 and Huesca on October 26, but it applied specifically to the 2024 season. Those dates do not describe the 2026 calendar and do not establish which circuit the new edition will join.

The cup’s geographical variety has been one of its defining features: different towns host races and provide their own settings, from urban surroundings to mountain-bike courses. Within that context, Jaca is a recognisable Pyrenean venue, but the landscape alone does not define the route. Specific technical information will be needed to know what terrain participants will encounter in 2026.

What the documented recent editions showed

The 2025 edition brought together nearly 160 young participants and 55 adults, according to coverage of the event. The elite race also decided the Aragon Cross Duathlon Championships. Aiara Garaialde won the women’s race and Raúl López Franco took the men’s title; the regional podiums also included Elena and Marta Bernal, Javier Álvarez and Aleix Sellares. These are 2025 results, not predictions or confirmations for 2026.

The report on that edition highlighted the school-age turnout and the organisational work required to stage a day with several formats. It also described a late-autumn atmosphere, with snow on the Pyrenees in the background. That scene provides context for the season, but it does not guarantee weather conditions in November 2026: temperature, rain, wind and trail conditions can vary considerably from year to year.

Another historical record, from 2015, listed an elite course with a 5-kilometre run, 23 kilometres of mountain biking and a final 2.5-kilometre run. The same day included a children’s race and an open, cadet and para category with different distances. This is a useful snapshot of the event’s development, but those figures belong to a specific edition more than a decade ago and must not be attributed to the current course.

The cross duathlon format and its demands

Cross duathlon alternates running segments with off-road cycling, usually with transitions in a shared area. In general, participants run, switch disciplines to ride a bike, then run again before reaching the finish. Each race’s rules determine the order, distances and regulations, so the exact Jaca format for 2026 remains unconfirmed.

The transition adds a different challenge to the physical effort. Athletes must leave their running gear, put on a helmet before taking the bike and respect their assigned space; after cycling, they change back to running without obstructing others. These are brief actions, but they can affect race pace and require familiarity with the rules. The official regulations will be the reference for the next edition’s procedures.

The bike element also changes how the course is experienced. A firm track, an uneven path and a technical section call for different skills, even though all can feature in a cross event. There is no confirmed information about the 2026 course surface, elevation, lap count or technical difficulty. For now, earlier descriptions should not be carried over to the new route, since organisers may change both the course and transition areas.

Jaca in autumn: scenery does not replace the race rules

Jaca lies in the Aragonese Pyrenees, and an autumn date brings particular conditions: shorter days and temperatures that can change quickly. The 2025 race took place on a chilly late-autumn morning, according to the available report, but that describes only that day. There is no reliable weather forecast for November 2026 this far ahead, and the route’s open or wooded sections have not been detailed either.

For a race in a mountainous or natural setting, trail conditions matter as much as distance. Moisture can make some surfaces slippery and mud can increase the effort required on a bike; in dry weather, dust and traction present different challenges. Without an updated course map, these are only general considerations about cross duathlon, not a description of the Jaca course.

The Pyrenean setting nevertheless helps explain the event’s appeal to athletes and spectators: a day of sport can bring together racing, school activities and a local atmosphere. The 2025 edition had support from volunteers and institutions, according to coverage at the time. The organisations involved in 2026 have not yet been announced, nor is it clear whether the same format will return; that history should not be mistaken for a new organisational announcement.

Children’s events and the work behind the race

Children’s events have been a visible part of recent editions. Around 160 young participants took part in 2025, and the day was included in the Aragon School Games, with categories adapted to age. That presence gives young athletes an entry point into duathlon, introducing running and cycling in a competitive setting, although a school-age event in 2026 has not yet been confirmed.

Running several categories in one day means coordinating schedules, courses and transition zones so groups can share the venue safely. It also involves managing volunteers, course marking and assistance, as well as keeping children’s and adults’ routes separate. Reports from earlier editions show how demanding that work can be, but they do not establish how many races will feature in 2026 or what services will be available.

The broader decline in participation mentioned by a club organiser during the 2024 cup presentation referred to the post-pandemic period and the circuit’s events as a whole. It was not a figure specific to the Mayencos Trophy or a current 2026 statistic. Entry numbers will depend on the call for participants, the calendar, the categories offered and other factors that can only be assessed once next year’s details are released.

What is still needed to complete the event information

The date and town identify the race, but they are not enough to plan participation. The regulations, start time, exact start location, course map and profile, category distances and equipment rules are still missing. The entry fee, registration period and any field limit have also not been announced. These details need to come from an official announcement, not from extrapolating an old edition.

Publication of the race regulations usually resolves questions that directly affect athletes: eligible ages, mandatory helmet use, bike specifications, transition order and possible penalties. If the event scores toward a cup or championship, the document also clarifies its competitive status. None of these points can be treated as confirmed for 2026 on the information currently available.

Edition numbers are not enough to infer the programme either. The available references use names and dates that do not align unambiguously across seasons, so the safest approach is to describe the next event without assigning it an edition number. That caution avoids blending historical records and keeps confirmed information separate from details the organisers have yet to announce.

A race that turns its attention back to Jaca

With November 8, 2026, marked on the calendar, the Mayencos Trophy once again has a specific date in Jaca. The event’s history, its connection to Aragonese duathlon and recent school-age participation explain its local importance, but the sporting details of the next race have yet to be defined. The available information confirms when and where, not what the course will be like.

Once the technical details are published, it will be possible to distinguish what is new in 2026 from features inherited from earlier editions. Until then, the strongest reference is the announced date and documented history: a longstanding race, a Pyrenean venue and a record of both elite and children’s competitions. Everything else — schedule, course, registration and categories — will need to be specified in the organisers’ official announcement.
