Guía de Isora 2027: date, distances and trail start times

Plan your race pace

Guía de Isora will host a new edition of its mountain race on Sunday, Jan. 24, 2027, with adult courses of 10, 20 and 32 kilometres. The start will be on Calle Ayuntamiento, with staggered start times beginning at 8:30 a.m. The event is organised by Guama Trail and will take place in the Tenerife municipality of the same name.

The event includes solo and pairs options. In the pairs category, both runners must complete the course together from the start to the finish. Registration is listed as open until Jan. 17, 2027, although it may close earlier if places fill up. Entry fees and the exact start time for each distance have not been confirmed in the information available.

Confirmed date, start and event details

The race is scheduled for Jan. 24, 2027, in Guía de Isora, on the island of Tenerife. The stated start area is Calle Ayuntamiento, in the municipal centre. The first participants are due to set off from 8:30 a.m., but starts will be staggered; that time should not be taken as the single start time for every distance.

The event is organised by Guama Trail. Published information gives the registration period as starting on June 5, 2026, at noon and closing on Jan. 17, 2027, at 11:59 p.m. That deadline depends on available places, so it does not guarantee registration will remain open until the final day.

For travel planning, it helps to distinguish confirmed details from those that still need checking. The date, municipality, start location and main distances are listed; however, the precise order of the starts, the time assigned to each course, aid-station locations and full participation rules are not detailed here. These points can affect race-day logistics and should be checked against the organiser’s updates as they are published.

Distances and race formats

The adult programme offers three options: 10, 20 and 32 kilometres. The choice has a substantial effect on the length and cumulative demands of the day, so distance alone is not enough to compare them. In mountain running, elevation gain, surface, weather exposure and the pace a runner can maintain for several hours also matter.

According to the event information, the courses are available individually and in pairs. The pairs format comes with an important condition: both runners must stay together throughout the course and cross the finish line together. It is not simply a shared registration for two runners competing separately; it is a format based on running and finishing as a pair.

The detailed listing gives the 32-kilometre course 2,029 metres of elevation gain, a figure that offers a clearer sense of its demands than distance alone. That is a substantial cumulative climb for a race of this length, although the figure does not reveal the gradient of each section or the full course profile. No equivalent elevation figure is available here for the 10- and 20-kilometre routes.

Some third-party listings show 30 kilometres for the longest course, while the more detailed event description lists 32. The difference may reflect an outdated listing or a discrepancy between calendars; based on the main programme, 32 kilometres is the advertised long-course distance. Runners should confirm the figure in Guama Trail’s current information before registering or planning their effort.

What is known about the mountain course

The race takes place around Guía de Isora, but the information reviewed does not provide a complete map or describe the terrain of each section. It is therefore not possible to state what proportion runs on singletrack, tracks or roads, or to identify particular climbs. What is confirmed is that this is a mountain event with three distances and that the 32-kilometre course has a published elevation gain of 2,029 metres.

For this kind of race, the total ascent does not tell the whole story. Two courses with the same elevation gain can feel very different if one concentrates the climbing into a few steep ramps while the other spreads it across long ascents, with technical descents in between. Path width, surface and how runnable the terrain is also matter. Without an official profile, specific features should not be assigned to the routes based on distance or Tenerife’s general landscape.

Tenerife includes coastal areas, mid-altitude terrain and steep mountains, but that geographical variety does not establish which landscapes the race will cross. Route details, checkpoints and any course changes remain subject to the organiser’s announcements. In particular, altitude and the direction each section faces can affect conditions, so broad statements about the island’s climate are no substitute for a forecast closer to race day.

Registration, deadlines and fees

The stated registration period opens on June 5, 2026, and is scheduled to close on Jan. 17, 2027. The deadline falls in the week before the event, but capacity may be reached earlier. The published date should therefore be treated as the planned final deadline, not a guarantee that places will remain available until then. The registration listing also indicates that entries are handled through an event platform.

Fees are arranged in tiers, with changes expected after Oct. 31 and Dec. 31, 2026, followed by the final period through Jan. 17, 2027. However, reliable amounts for each tier are not available, so it is not possible to give a specific price without risking an inaccurate figure. Isolated numbers on some calendars do not clarify whether they refer to the current fee, a particular distance or a generic listing.

Before registering, it is useful to check what the entry includes, whether prices differ by distance or format, and what policy applies to withdrawals or participant transfers. Information reviewed here also does not confirm whether there are age categories, mandatory equipment requirements or special rules for pairs. The current registration page and the organiser’s rules are the appropriate references for these questions, rather than estimates from event aggregators.

How to assess the demands of each distance

The 10-kilometre course is the shortest option, but that does not automatically make it easy: a relatively short mountain route can still include steep slopes or uneven ground. The 20-kilometre course means a longer period of effort, while the 32-kilometre option combines greater distance with the elevation gain published for the long course. The official profile, once available, will be essential for comparing the actual difficulty of the three options.

Distance alone cannot predict how long someone will take to finish. Experience on trails, the ability to hike steadily uphill, confidence on descents and the conditions on the day all affect finishing time. A runner accustomed to road running may find their pace changes considerably on mountain paths, where shifts in gradient and surface interrupt a steady stride.

In general, preparing for a mountain race means getting used to varied surfaces and elevation, while adjusting effort to the expected duration. On a long course, effort management matters as much as speed: starting too fast on a climb can take its toll later, while conserving energy can help runners handle descents with control. These are general principles, not a description of Guía de Isora’s specific route.

The pairs format adds another factor to pacing. Both runners share the course and must finish together, so differences in ability can influence their strategy and race experience. Before choosing this option, participants should bear that condition in mind and check how the rules define running together. The pair competes as a unit throughout the course, not just at registration.

Race-day logistics

The announced start on Calle Ayuntamiento places the event centre in Guía de Isora, but it does not establish where bib collection, parking, services or the finish will be located. Nor is it confirmed here whether the finish is at the start. Those details are often included in final instructions and can determine whether runners arrive with time to spare or have to deal with transport at the last minute.

Because starts are staggered from 8:30 a.m., each runner will need to check the start time for their distance and format. The general start time does not confirm the time for a specific category. It is also worth checking the location of each service and bib-collection instructions, especially if the 10-, 20- and 32-kilometre events have different schedules.

Runners travelling from another island or mainland Spain should allow time to reach the municipality and get to the start area. No confirmed information is available here about event accommodation, dedicated transport or road closures. Guía de Isora is the reference municipality, but final planning will require checking local and organiser announcements as the date approaches.

A Tenerife event awaiting its final race rules

The main details for the 2027 edition are set: Jan. 24, a start in Guía de Isora and distances of 10, 20 and 32 kilometres, with solo and pairs options. The detailed listing gives the long course 2,029 metres of elevation gain. Registration is advertised as open until Jan. 17, subject to remaining places, while exact prices and several operational details have not been specified.

The discrepancy between listings over whether the longest course is 30 or 32 kilometres makes it worth watching for official updates, as does the lack of individual start times for each race. As January approaches, the course profile, checkpoints, rules and race-day instructions will make it possible to assess the challenge more precisely. For now, the event is presented as a mountain race with a broad programme, whose full demands will depend on the final information from Guama Trail.
