Valdetorres will host a 40-kilometer Backyard race in 2027

Plan your race pace

The next edition of the Valdetorres de Jarama endurance race has a confirmed date: June 18, 2027. The Madrid-region town will once again host a Backyard-style event, with a 40-kilometer distance announced. So far, however, no confirmed details have been released for that edition on the start time, entry fee, registration, final course or services.

Information from previous years helps explain the kind of challenge it may involve, but should not be confused with the 2027 schedule. The 2026 edition was described as having 6.7-kilometer loops and several distances, including a race of about 40 kilometers; those details are background, not guarantees for the next event. The date is set; the rest requires confirmation from the organizers.

Confirmed date and details still pending

The event is scheduled for Friday, June 18, 2027, in Valdetorres de Jarama, a municipality in the Community of Madrid. Available information places the race in June, and the additional data confirm the specific day. No 2027 start time is listed, however, and no meeting point has been validated for that edition, so it is best not to automatically carry over the location used in previous years.

Practical details that affect any plans are also pending: registration opening and closing dates, capacity, fees, race-day services and bib-pickup arrangements. In 2026, the start was reported to be on Calle del Sol, and the municipal sports center was used as a base area, but organizers must confirm whether those locations will be used again. The historical address can offer guidance, but it is not a substitute for an official announcement.

The same caution applies to distances. The 2027 reference information lists a 40-kilometer race, while the 2026 program included 20.1- and 40.2-kilometer options and an ultra distance. Until the regulations for the new edition are published, it is not safe to assume that every distance will return or that the courses will be identical.

What it means to run a Backyard

A Backyard race is built around a short course that runners repeat. In its usual format, each runner must complete a lap within a time limit and return to the start before the next one begins. The total distance depends on how many loops are completed and on the specific rules of each event. It is not a conventional race in which everyone sets out to run a fixed distance from start to finish: pace and consistency matter as much as endurance.

In Valdetorres, the 2026 edition was described as having a loop of about 6.7 kilometers. The 40.2-kilometer option involved six laps, while the half-marathon covered three. An ultra option with successive laps was also mentioned. Those details show how the previous race was organized, but the final distance and 2027 rules should be checked in the updated event information.

The lap format changes how effort feels. In a fixed-distance race, runners generally distribute their energy toward a known finish; here, each lap may mean a short break, a decision about food or drink, and preparation to head out again. In events with an hourly cutoff, arriving late may mean missing the next start. The strategy is not to run every lap as fast as possible, but to maintain a sustainable pace and use the intervals wisely.

The course and what is known about the previous edition

References to the 2026 event describe a race mainly on asphalt, with a repeated circuit around Valdetorres de Jarama. Streets and nearby paths were also mentioned, although no full official profile or detailed elevation information was provided. For that reason, a more precise description of the 2027 terrain would be premature. Surface, turns, sections shared with traffic and markings depend on the route approved for the next edition.

Repeating a course has an obvious advantage: runners can become familiar with each section and measure their effort lap by lap. But it also concentrates strain on the same foot placements and turns. A gentle slope that is barely noticeable at first may become apparent after several hours, while a turn taken in the same direction can bother the feet, ankles or hips. The loop’s apparent simplicity does not eliminate accumulated fatigue.

Asphalt often allows for a predictable stride and makes shoe selection simpler than on a technical trail. That does not mean the course is uniform or closed to traffic: the previous description indicated that vehicles could still be on the road, requiring participants to follow traffic rules. For 2027, runners will need to wait for a course map and regulations that should specify the surface, crossings and safety measures.

June heat and a night race

The June date makes it worth considering both heat and darkness, although the 2027 schedule has not yet been confirmed. The 2026 edition was reported to start at 9 p.m., with lighting required for the nighttime section; that does not guarantee the same schedule will return. An evening or nighttime start may reduce sun exposure on some sections, but it can also extend the effort through changing conditions.

Inland Spain can bring hot June afternoons and cooler nights. Actual temperatures vary from year to year and cannot be determined months in advance. In an endurance event, peak heat is not the only factor: sun exposure, wind, humidity, time on course and the ability to drink regularly all play a role. Hydration should match the conditions and individual effort, rather than follow a universal amount.

If the event again includes nighttime sections, a reliable headlamp and visible clothing will matter, but exact requirements must come from the 2027 rules. In 2026, the listed equipment included a headlamp, a red rear light for nighttime running and a mobile phone. Before preparing gear, runners should check which items are mandatory, how long batteries will last and whether spares are permitted. A change in temperature during breaks may also make a light layer useful, depending on the schedule and official rules.

Registration, fees and organization

No confirmed information is available on the 2027 entry fee, registration opening date or bib capacity. Fees listed for 2026 were 25 euros for the half-marathon, 45 euros for the 40.2-kilometer distance and 55 euros for the ultra in an initial pricing tier; the amounts later increased. Those are historical prices and should not be treated as current fees.

The previous edition also listed a maximum of 150 participants and online registration until a few days before race day or until places sold out. That limit and schedule could change. Final information should identify the organizer, registration platform, what the entry includes and how cancellations or name changes are handled. Until it is published, it is not possible to confirm that registration is open or provide a reliable link or price.

Some endurance events provide an area where participants can leave clothes and food between laps. For the 2026 edition, the municipal sports center was described as a support area with changing rooms, showers and a place to rest. The availability of those services for the next event has not been verified. The regulations and organizers’ information will be the reference for logistics, including spectator access and facility use.

Preparing for a 40-kilometer distance

A race of about 40 kilometers requires a sufficient base to spend several hours running and manage fatigue without accelerating impulsively. Training volume and intensity depend on each person’s history, experience and fitness. In a lap-based format, it can also help to get used to maintaining a comfortable pace and resuming the run after a break. Consistency is usually more valuable than a fast start.

Long runs help show how the body responds to sustained effort, but there is no need to replicate the entire race or increase training load without progression. Alternating surfaces and paces can help reduce repetitive strain, while practicing food and fluid intake during runs makes it easier to identify options that work. Sports nutrition is not the same for everyone: any strategy should be tested gradually and adjusted to the event’s duration and personal needs.

Rest, sleep and signs of excessive strain also deserve attention. Pain that changes the way someone runs, dizziness, confusion or severe discomfort are not symptoms to ignore in order to meet a goal. In long events, reducing effort or withdrawing is part of responsible participation. Anyone dealing with an injury, illness or medical concern should consult a health care professional. Preparation cannot be separated from safety.

Gear and managing the laps

Suitable equipment depends on the course and regulations, both still pending for 2027. For an asphalt race, shoe selection generally prioritizes comfort and a fit that has been tested in training; wearing new shoes on race day adds an unnecessary variable. Familiar socks, clothing that does not chafe and sun protection may be more useful than collecting accessories. Proven comfort matters more than a last-minute purchase.

If the race runs through the night, reliable lighting and visible clothing become important. A dry layer for rest periods may also be useful, though mandatory equipment will only be clear once the rules are published. In a repeated circuit, gear left near the start should be organized so breaks do not become a race against the clock. A simple plan for drinking, eating and changing clothes can prevent rushed decisions when fatigue sets in.

Time between laps is not always complete recovery. Eating too quickly, sitting until chilled or leaving with barely enough time can make the next loop harder. Each participant will need to determine how much rest they need; in races with scheduled starts, a watch helps track the time available, but it should not distract from warning symptoms. The break is part of the effort, not a pause unrelated to the race.

Valdetorres de Jarama as a setting

Valdetorres de Jarama is in the Community of Madrid and offers a small-town setting, different from that of a major city race. References to previous editions place the activity near the town center and describe a loop course, but no map has been confirmed for 2027. The start location, parking and access areas will need to be checked when official information is released.

Logistics in a small town can have particular challenges: public transport schedules, lodging availability and places to eat may differ from those in a large city. Anyone traveling from elsewhere should check how to get there and where to park, without assuming reserved parking or special transport will be available. It is also sensible to check municipal guidance and organizer instructions to avoid blocking residential access. Travel planning is part of the event experience.

Lap races often create a close-knit atmosphere because runners and spectators repeatedly meet near the start area. One lap may pass with conversation; the next, in silence and focused on moving forward. That contrast is part of the format’s appeal, but it does not replace practical details: planning a trip requires confirmed directions, schedules and services, which have not yet been provided for the new edition.

The regulations will define what comes next

The June 18, 2027, date makes it possible to place the race on the calendar, and the reference to 40 kilometers outlines the main challenge. But essential details such as the start time, final distances, price, course and registration are still awaiting confirmation. Information from 2026 provides context, but does not replace the 2027 announcement.

Once the regulations are published, it will be possible to see clearly what remains from the previous format and what changes: lap length, time limit, start, services, required gear and participation rules. Until then, the most accurate approach is to treat only the announced date and location as confirmed and avoid presenting estimates as facts. For an endurance race, that distinction matters as much as pace: good preparation starts with knowing what has actually been established.
