The Alboraya Night 10K Against Cancer 2026 takes place on Saturday, June 27 at 10 p.m., and its most important change is not just cosmetic: the later start time changes how runners should approach the race. Moving a June 10K in Valencia into the night can reduce direct heat stress, but it does not automatically turn the event into a cool, easy effort.
For popular runners, the appeal is obvious: a certified 10-kilometre course, a local race atmosphere, a charity purpose, a night start and a place in the RunCancer by Diputacio de Valencia race circuit. The smart way to race it is to treat it as a fast 10K if managed well, but one shaped by summer timing, humidity, start-area crowding and the temptation to go out too hard.
What is the Alboraya Night 10K 2026?
According to the official race rules, Alboraya City Council organises the 13th edition of the 10K Alboraya Against Cancer with support from the local cancer association board, Xufarunners Alboraya and Socarrat Studio. The race is scheduled for Saturday, June 27, 2026 from 10 p.m. on a 10,000-metre course certified by the Spanish athletics federation.
The event is open to federated and non-federated runners who are at least 16 years old on race day. It is also included in the regional road-race calendar of the Valencian athletics federation and in RunCancer Valencia. The official time limit is 1 hour and 20 minutes from each runner’s start.

- Start time: 10 p.m.
- Location: Alboraya, Valencia, Spain.
- Distance: certified 10,000 metres.
- Minimum age: 16 on race day.
- Time limit: 80 minutes.
- Entry cap: 2,000 bibs, with a maximum of 1,200 race packs including the runner bag.
Why a 10 p.m. start changes the race plan
RunCancer describes the 10 p.m. start as the main new feature for 2026, introduced to help limit the impact of high temperatures at this time of year. That makes sense: late June in the Valencia area can be tough for a 10K effort, even after sunset.
But running at night does not remove every environmental risk. Asphalt can hold heat, humidity can remain high and your body may need more time to settle if the day has been hot. The danger is starting as if this were a winter 10K because the evening air feels more forgiving, then discovering around kilometre 4 that your body is not cooling as well as expected.
A practical approach is to run the first two kilometres with restraint, even if the atmosphere pulls you forward. In a summer night 10K, the goal is not to win seconds in the opening stretch. It is to reach kilometre 6 with enough control to keep racing. If you are chasing a personal best, think progressive: controlled first third, steady middle section and the final 3 kilometres adjusted to your breathing, heart rate and legs.
Start corrals, predicted pace and why placement matters
The regulations state that there will be a single start, with runners separated into corrals based on accredited or predicted finish time provided during registration. The purpose is to place runners with others of a similar level and make the first part of the race safer and smoother.
That matters more than it may seem. In a night race with a dense start and a wide range of abilities, standing too far forward can push you into a pace you cannot sustain. Standing too far back can turn the opening minutes into constant overtaking, braking and lane changes. The best move is to give a realistic predicted time and respect your assigned corral.
The rules also make one point clear: runners will not be able to move into a faster corral at bib pickup. If you want to start near runners of your real pace, that decision has to be made when entering, not on race day.
Registration, prices and bib pickup
Registration is handled through Carreraspopulares.com. The rules set a 2,000-runner limit and distinguish between entries with and without the runner bag. Official price tiers are 7 euros without the bag and 10 euros with the bag until April 14, 10 and 13 euros until May 31, and 12 and 15 euros from June 1 to June 25. Clubs entering more than 10 runners at the same time have a listed price of 10 euros with the runner bag, while places remain available.
There is one date detail runners should handle carefully. The rules say personalised entries close on Monday, June 22 at 23:59 and non-personalised entries close on Wednesday, June 24 at 23:59 or when the race reaches capacity. The Carreraspopulares.com event page shows a registration period through June 25, while the RunCancer news item refers to June 22. The safest advice is simple: check the registration platform before assuming places are still available or before making travel plans.
Bib and technical-garment pickup is scheduled at Ciudad del Deporte, on Calle San Isidro Labrador in Alboraya. Official pickup windows are Friday, June 26 from 18:00 to 21:00, and Saturday, June 27 from 11:00 to 14:00 and from 18:30 to 21:30. If another person collects your bib, they can do so with a copy of your ID, another accepted identity document or the entry confirmation, including a digital version shown on a phone.
Aid stations and race-day logistics
The course will have three liquid aid stations at kilometres 2.5, 5 and 7.5, plus post-finish refreshment. For a summer 10K this is useful, but it should not tempt runners to improvise hydration all day. What you do from the morning onward matters more than the cup you may grab halfway through the race.
There will be free bag drop at Ciudad del Deporte on race day. The night start also changes small but important details: dinner, sleep, travel, parking and muscle activation. If you usually race in the morning, do not arrive at 21:40 with your body switched off. Have a light early evening meal with enough time to digest, hydrate steadily, walk before warming up and leave 10 to 15 minutes for mobility, easy jogging and a few short strides.
How to race it depending on your goal
- If your goal is to finish well: run by feel, avoid checking pace every 200 metres and use the first aid station only if you need it. Your race really starts when you pass 5K still breathing under control.
- If you want a personal best: do not chase seconds in kilometre 1. Adjust for heat and humidity, accept an opening pace 3-5 seconds per kilometre slower than target, and recover later if your body responds.
- If you are returning from injury: respect the 80-minute limit, but do not turn the race into an all-out test unless your recent training supports it. Night atmosphere can make you run harder than planned.
- If you run with a group: agree on the real pace before the start. In a 10K with corrals, night timing and summer conditions, a group helps when it keeps you organised; it hurts when it turns the first section into a chase.
The charity value of Alboraya
This is not only a competitive race. RunCancer presents Alboraya as the fifth event in the 2026 RunCancer by Diputacio de Valencia race circuit, after Rafelbunyol, Montserrat, Paterna and Paiporta. The organisation also notes that the 2025 Alboraya 10K brought together more than 1,419 participants and raised 17,250 euros, with the 2026 edition aiming to beat those figures.
RunCancer says 100% of proceeds from its events go to cancer research projects promoted by the Spanish Association Against Cancer in Valencia. Across the circuit’s history, the organisation reports more than 3.36 million euros raised and more than 732,000 participants since 2015.
There will also be a Mini 10K Alboraya Against Cancer for children up to age 14, with youth races on Friday, June 26 from 19:30. That family and charity setting is part of why the race matters beyond the clock: it gives runners a way to compete, take part and support a local cause with continuity.
Final runner checklist
- Confirm your entry and real place availability on the official registration platform.
- Check bib-pickup times and avoid leaving collection to the last possible slot if you can.
- Use or respect a corral that matches your real current fitness.
- Hydrate well during the day, but do not arrive with a heavy stomach.
- Warm up progressively: mobility, easy jogging and a few short strides.
- Start under control, especially if humidity or stored heat is noticeable.
- Use aid stations sensibly without relying on them to fix poor pre-race hydration.
The Alboraya Night 10K 2026 has the ingredients of a strong summer popular race: a certified distance, a special start time, a charity cause and a town-based atmosphere. To race it well, the trick is not to trust the night blindly. Treat it as a serious 10K that rewards patience from the first kilometre.
