Gaucín Backyard Ultra 2027: date, course and format

Plan your race pace

Gaucín will host the fifth edition of its Backyard Ultra on April 10, 2027, an endurance race in which runners repeat the same loop until only one person remains able to complete a lap within the allotted time. The start is scheduled for 8 a.m., and the event may continue into the following day: there is no set finishing distance.

The course measures 6.706 kilometers per lap and runs through the lower Genal Valley in the Serranía de Ronda. Chestnut, holm oak and pine trees line a route made up of 85% tracks and trails, with the remaining 15% on asphalt or concrete. The combination of elevation, uneven ground and short breaks makes every new start a fresh physical and mental decision.

An endurance event in the Serranía de Ronda

The race will take place in Gaucín, in Málaga province, amid mountain scenery that changes as the hours pass. The fifth edition is scheduled for April 10, 2027, with an 8 a.m. start. Available information places the event between Saturday, April 10, and Sunday, April 11, a timeframe consistent with a format that can run through the night, although no finish time has been announced.

The name Backyard Ultra describes both a race format and an elimination-style endurance event. The winner is not necessarily the fastest runner or the person who covers a set distance before everyone else. The aim is to stay in the race, lap after lap, until one participant completes the final valid loop alone and the others can no longer continue.

Available race information lists Gaucín Town Hall as the organizer, supported by Club Deportivo Gecko Gena. It also gives a participant limit of 250. The entry fee, registration period and any eligibility requirements have not been confirmed in the information reviewed, so no specific prices or deadlines should be assumed.

How the Backyard Ultra format works

Every runner must cover the same 6.706-kilometer loop within each hour. A new start takes place on the hour, whether the previous lap was completed with time to spare or just before the next signal. Any time left becomes a short break to drink, eat, change clothes or sit down, but not a full hour of rest.

The rule turns pacing into a balancing act. Running too fast can use energy without providing a decisive advantage, while using every available minute leaves little time to recover and prepare for the next lap. The total distance increases steadily: ten laps amount to 67.06 kilometers, and 20 equal 134.12 kilometers, provided each is completed within its time limit.

The finish does not depend on a traditional finish line or a clock stopping at a predetermined distance. The race continues as long as participants start and complete the loop according to the rules. The last person to complete a lap alone wins; if nobody completes the required final lap, there is no winner. The competition is therefore built around the other runners, not a preset mileage target.

A loop through chestnut, holm oak and pine trees

The course uses the lower Genal Valley, a mountain landscape where woods and tracks shape much of the experience. The same route is used by day and night, so runners do not face a new course after sunset: they return to familiar bends, surface changes and landmarks, although visibility and fatigue can affect how they perceive them.

The surface is approximately 85% tracks and trails, with 15% asphalt or concrete. That mix means the course is neither entirely dirt nor a road race with just a token trail section. The changing surfaces require runners to adapt their footing and may increase the strain on their legs and feet after repeated laps.

Published details indicate around 180 meters of elevation gain per lap. Multiplied across several loops, that figure shows how the effort grows: ten laps would amount to about 1,800 meters of cumulative elevation gain, although the actual total depends on the number of laps completed and the course’s precise characteristics. No official detailed profile has been provided to confirm gradients, elevations or the distribution of climbs.

The final distance is not decided before the start

In a conventional race, the distance is known from the outset. In Gaucín, the total mileage remains open. The format does not require runners to complete a marathon, a particular ultradistance or a fixed number of laps: each hour adds another 6.706 kilometers for those still in the race.

The progression gives a sense of the scale of the challenge without confusing calculations with an official distance. A runner completing 12 laps will have covered 80.472 kilometers; 24 laps equal 160.944. The race can continue beyond those totals if runners are still able to start again, but the available information cannot predict how long the 2027 edition will last.

The announced limit of 250 entries sets the maximum capacity, not the number of people who will ultimately start. The number of participants in previous editions and the event’s lap record have not been confirmed either. Without consolidated official data, figures in external listings should not be treated as verified records or presented as a reliable estimate of participation.

How the shift from day to night changes the race

The morning start gives runners daylight for the first laps, but the schedule may take them into the night and, if the event continues, back to dawn. Fatigue affects movement on the trail and the way runners judge the time available. A familiar bend can demand more attention when only the nearby ground and a headlamp beam are visible.

In this format, night is not a separate stage but another phase on the same loop. The daytime and nighttime route is identical, so repetition may help runners memorize it, but it does not remove the differences in temperature, light or perception. Paying attention to the ground remains important on every lap, particularly on dirt tracks and trails where uneven sections may be harder to see.

The supplied details do not specify mandatory gear, aid-station services, support points or lighting rules. Those requirements should be checked in the organizer’s regulations when they are published or updated. Until then, it is not possible to confirm what equipment the race requires or what resources will be available during the event.

What is known and what remains unconfirmed

The confirmed information establishes the main details: the date is April 10, 2027, the start is at 8 a.m., and the location is Gaucín. It also describes hourly laps, the length of each loop, the natural setting and the approximate mix of surfaces. The announced edition is the fifth of the event, which is described as the first Backyard Ultra in Andalusia.

The entry fee, registration opening and closing dates, sign-up process, bib collection times and full regulations have not been reliably confirmed. One listing places the event at Calle Velasca 18 in Gaucín, but an official start location has not been provided. That address should not be treated as the official start point without explicit confirmation from the organizer.

An official website domain is also not explicitly provided in the reference information. It is therefore not possible to confirm a registration link or attribute unlisted instructions to the event. Anyone planning travel or participation will need to check practical details through the organizer’s channels once they are published, particularly the exact start location and race conditions.

A race that measures consistency, not just speed

Gaucín’s Backyard Ultra offers a distinctive endurance challenge: repeat a relatively short distance within a strict time limit, manage the break and start again. At first, the loop may seem manageable; with each new start, however, mileage, elevation and time spent awake accumulate. The challenge is sustaining an effort routine over many hours, not simply completing one fast race.

The Genal Valley setting provides a counterpoint to that format. Tracks, trees and changing light offer natural landmarks, while the repeated course imposes an almost ritual rhythm. Each lap brings runners back to the same starting point, but not in the same physical condition. The event becomes a series of small decisions: how much energy to save, when to eat and whether there is enough left to head out again.

With the date set for April 10, 2027, Gaucín is preparing an edition whose outcome cannot be written before the first start. The known course and start time help define the challenge; its duration, however, will depend on those who can stay on their feet and complete each lap. In a race with no predetermined final distance, the finish arrives when only one person can keep going.
