The Colmenar Viejo Night Run-Walk 2026 takes place on Saturday, July 18, at 9 p.m., starting and finishing on Avenida de los Toros. At first glance, it looks simple: 10 kilometres, a summer evening and a local race atmosphere. Look a little closer and it becomes more interesting for runners: a rural night 10K over paths and livestock tracks, with a required headlamp, tape-marked navigation and a parallel non-competitive walk over the same distance.
That context changes the way you should approach it. This is not just another urban 10K where you settle into a pace group and stare at your watch. Darkness, rural terrain, residual July heat and the mix of runners and walkers all matter. Run it with patience and it can be a memorable summer race. Treat it like a flat city personal-best attempt from the first metre and it may start to feel messy before halfway.

The main details are listed on the official race website, in the race regulations and in the announcement from Colmenar Viejo Town Council. The organisers confirm a 9 p.m. start, bib pickup from 6:30 p.m. and a 10K route shared by the race and the walk.
What makes this night 10K different
The defining feature is the setting. Colmenar Viejo is not offering a straight-line city race with constant street lighting and predictable reference points. The route uses rural paths and livestock tracks, which means runners need to read the ground, follow the markings and stay aware at junctions. The regulations state that the course is marked with tape rather than fully barriered, and that matters much more after dark than it would on a city-centre loop.
The second difference is the two-format structure. Competitive runners get a chip-timed 10K with category awards. Walkers get a neutralised, guided, non-competitive 10K. That makes the event more inclusive and more social, but it also asks everyone to behave well. Runners need to overtake with space and patience. Walkers need to keep an orderly rhythm. A good night race depends as much on shared awareness as on fitness.
There is also a strong community angle. The race includes categories for athletes with disabilities, and the regulations list free entry for participants with disabilities. The walk opens participation to younger children from age seven, with adults accompanying those aged seven to twelve. So this is a popular race in the broadest sense: competitive if you want to race hard, accessible if you want a different summer evening outdoors.
Entries, fees and bib pickup: do not leave it late
The regulations and the Town Council information say entries remain open until 11:59 p.m. on Friday, July 17, or until available bibs run out. The Deporticket page lists the available options and fees including processing costs: 12.50 euros for the 10K race, 10.50 euros for the adult walk, 6.20 euros for younger walkers and family packs for two, three or four participants.
Because the event has a limited field and the platform may display its own payment cut-offs, the practical advice is simple: check real-time availability before planning your weekend around it. If you are entering as a family group, collecting documentation or relying on a specific registration category, give yourself time to solve small admin issues. The Friday-night deadline is not an invitation to wait until the final minute.
Bib pickup takes place on race day from 6:30 p.m. in the start/finish area. The regulations say participants need ID to collect their own bib, and authorisation plus a copy or image of the ID if collecting for someone else. Minors need written authorisation from a parent or guardian. Keeping a copy of your registration on your phone is a small habit that can save an awkward pre-race problem.
How to race the 10K if you want to compete
The main mistake would be to chase a personal best from the first minute. Yes, the distance is 10 kilometres, but the night setting, rural surface and possible summer heat call for a more measured race. Starting 5 to 10 seconds per kilometre slower than your ideal 10K pace for the opening two kilometres is not weakness. It lets you settle your breathing, check your headlamp angle, read the ground and avoid wasting energy on nervous overtaking.
- Kilometres 1 to 2: find space, look down often and avoid sharp moves to pass other runners.
- Kilometres 3 to 6: settle by effort rather than GPS alone; paths, turns and signal loss can make pace data noisy.
- Kilometres 7 to 8: decide whether you can progress. If you are breathing hard or struggling to read the ground, hold your effort.
- Kilometres 9 to 10: only push if your form is still clean. A chaotic night sprint is rarely worth the risk.
Use your normal road 10K pace as a reference, not as a rule. In a race like this, perceived effort matters more than perfect splits. If you notice you are checking the watch every few seconds, you are probably looking away from the things that matter most: the ground, the markings, the people around you and the organisers’ instructions.
Headlamp use, safety and overtaking
The headlamp is not a decorative item here. The regulations require a front light for both the race and the walk, and the organiser includes one in the runner pack. Even so, if you already own a headlamp you trust, test it before race day. A night race is the wrong moment to discover that the strap slips, the beam points too high or the battery is weak.
A good headlamp should light the ground a few metres ahead, not shine into another runner’s face. If the beam is too high, you can dazzle people. If it is too low, you lose reaction time. When running in a group, avoid sitting directly on another runner’s heels. You will end up depending on their light and their foot placement. A small gap is safer, especially near junctions, narrow sections or darker patches.
When overtaking, call it calmly, choose a wider section and wait if the space is not there. The rules remind runners to give way safely when asked, but that does not make every pass automatic. In a popular night race, saving two seconds is not worth creating a risky moment. Communication, patience and steady rhythm are usually faster than weaving through the field.
What to bring besides your bib
- Reliable shoes: you may not need aggressive trail shoes in dry conditions, but avoid unstable racing shoes if you do not trust them on paths.
- Light, visible clothing: July evenings can stay warm, and extra visibility is useful.
- A tested headlamp: even if the organiser provides one, using a familiar light can reduce stress.
- Fluid before the start: there will be liquid aid on course and solid/liquid aid at the finish, but arrive already hydrated.
- ID and authorisation if needed: especially for minors or when collecting another person’s bib.
- Respect for the environment: the regulations explicitly require participants not to leave waste outside the bins.
The event also offers a free bag-drop service in the start/finish area. That makes it worth bringing a dry shirt or a light layer for after the race. It may feel unnecessary before the start, but once you finish sweaty at night and your heart rate drops, a dry layer is a quiet luxury.
If you are walking: it is not a slow race, it is a different plan
The 10K walk is neutralised, guided and non-competitive. The goal is not to get there first, but to complete the route safely and comfortably. For families, friend groups or people who do not run continuously, it may be the best way to enjoy the night atmosphere without the pressure of a timed race.
Still, walking 10 kilometres at night is not something to improvise completely. Wear comfortable shoes, adjust the headlamp before starting, avoid new socks and remember that you will be moving for a while. The event has a three-hour maximum duration, so the walk is accessible, but it still requires a real willingness to cover the full distance.
A simple pacing guide for choosing your goal
| Runner profile | Reasonable goal | Practical key |
|---|---|---|
| You want to compete | Run a controlled negative split | Keep the first 2K patient, then progress only if visibility feels good |
| You train regularly for 10Ks | Run slightly more conservatively than on a city-road course | Use effort, not GPS alone |
| It is your first night race | Finish with confidence | Prioritise safety, headlamp position and visual references |
| You are doing the walk | Complete 10K without rushing | Comfortable shoes and conversation pace |
The smartest way to read the Colmenar Viejo Night Run-Walk 2026 is not “how much time can I take off my 10K best”, but “how well can I run in a different environment”. That is what makes it useful for everyday runners: it tests control, awareness and rhythm in a setting that feels very different from a Sunday-morning city race.
Runner verdict
If you live in Madrid or want a different kind of July race, Colmenar Viejo offers a strong mix: manageable distance, night start, rural surroundings and the option to race or walk. The hard part is not underestimating it. Ten kilometres can sound short until you are doing them at night, in summer, while following tape markings and managing a headlamp.
To run it well, keep the plan simple: arrive early, collect your bib with time to spare, test the headlamp, hydrate before the start and do not give away the first kilometres. If you feel smooth halfway through, you can build. If you go out too hard, the darkness will not hand those seconds back later.
