Best Halloween Fitness Events UK 2025

Where fitness meets fright — the most fun you’ll have breaking a sweat this October.

Every October, fitness enthusiasts and thrill-seekers trade in their standard gym sessions for something a little darker, spookier, and far more entertaining: Halloween-themed fitness events.

 

Whether it’s a midnight trail run through foggy woods, a spin class full of zombies, or a costumed HIIT session at your local gym, these events combine the adrenaline of training with the excitement of Halloween.


If you’re ready to swap your usual gym routine for something wild this autumn, here’s your complete guide to the best Halloween fitness events for adults in the UK for 2025 — plus tips on Halloween gym costumes, themed sport activities, and how to make your workout both festive and fierce.

 

Why Halloween and Fitness Make the Perfect Match

Halloween isn’t just for trick-or-treaters or horror movie marathons anymore. In recent years, it’s become one of the most creative periods in the fitness calendar — a chance for gyms, running clubs, and outdoor trainers to add a playful, social twist to regular training.


Think about it:

  • The weather’s crisp, perfect for running.

  • Everyone’s in the mood for something different.

  • Costumes add energy, laughter, and team spirit to workouts.

  • And let’s be honest — after a few pumpkin spice lattes, most of us need a solid sweat session.

 

So, if you’re ready to get moving while celebrating spooky season, there’s never been a better time to explore the growing world of Halloween fitness events.

 

1. Halloween Parkruns (Nationwide)

If you’ve ever taken part in a Saturday morning parkrun, you’ll know the community vibe is unbeatable — and it gets even better around Halloween. Across the UK, hundreds of local parkruns host Halloween-themed runs where participants show up in full costume: witches, skeletons, ghosts, even the occasional pumpkin sprinting toward the finish line.


The atmosphere is light-hearted but energetic, with some runners chasing new personal bests while others simply come for the fun. Many events also raise funds for local charities.


Where: All across the UK — check your nearest parkrun’s page for dates.

When: The Saturday closest to Halloween (October 25th or November 1st, 2025).

What to wear: Try a Halloween gym costume that’s breathable and safe to run in — think black compression leggings, a lightweight cape, and glow-in-the-dark accessories.


Pro Tip: If you’re representing your gym or team, get everyone to wear matching Halloween-themed shirts for easy group photos and social posts.

 

2. Chase the Moon Halloween 5k & 10k — London

Hosted by RunThrough, this night-time event takes place at the iconic Queen Elizabeth Olympic Park. Thousands of runners, many in costume, take on a flat, fast route under glowing Halloween lights. The atmosphere mixes serious running with serious fun.


Music, costumes, and eerie lighting make this one of the most photogenic running events of the season — and a great opportunity for your halloween sport activities content.


Where: Queen Elizabeth Olympic Park, London

When: Wednesday, 29 October 2025

Why go: High-energy crowd, official timing, medals, snacks, and a great night-run vibe.

Costume idea: Black and orange compression gear, vampire fangs, reflective tape, and maybe a splash of fake blood (just not near your trainers).

 

3. Brutal Halloween — Hampshire

For those who prefer mud over treadmills, Brutal Runs are some of the toughest (and most rewarding) off-road races in the UK. The Brutal Halloween event takes place at Hogmoor Inclosure and features 6.6k and 10k options through mud, hills, and water crossings — all under eerie forest lighting.


It’s as close to a horror-movie obstacle course as you’ll find — and definitely not for the faint-hearted.


Where: Hogmoor Inclosure, Bordon, Hampshire

When: Saturday, 25 October 2025

Expect: Mud, laughter, teamwork, and headtorches cutting through misty air.

Perfect for: Groups of friends or fitness teams looking for a Halloween challenge that pushes limits.

 

4. Halloween Twilight Run — Haldon Forest

If trail running by torchlight sounds thrilling, the Haldon Forest Twilight Run is for you. This event, organised by Purple Gecko Events, invites runners to embrace the night in full Halloween spirit — fancy dress encouraged. Expect glowing headlamps, forest trails, and an atmosphere that’s more “spooky adventure” than scary.


Where: Haldon Forest, near Exeter

When: Saturday, 26 October 2025

Vibe: Family-friendly, but plenty of adults take part in serious kit and costume.

Top tip: A Halloween gym costume with reflective or LED accents keeps you safe and on theme.


5. The Halloween Blood Run — Belfast

Not all Halloween runs are competitive — the Blood Run in Belfast is equal parts fitness and fundraising. Participants walk or run 2.5 km or 5 km to support local blood donation initiatives, often in full costume. It’s a great option if you want to join a Halloween fitness event without the pressure of racing.


Where: Ormeau Park, Belfast

When: Sunday, 26 October 2025

What makes it special: It’s for a cause — and everyone from serious runners to first-timers joins in.


6. Halloween Gym Events — Local Fitness Studios Nationwide

Don’t overlook your local gym — October is when studios and chains across the UK start hosting Halloween gym events that mix workouts with atmosphere.


Popular formats include:

 

  • “Thriller” dance workouts (Zumba or cardio dance to Michael Jackson’s hit)

  • Zombie HIIT (circuit training with spooky lighting and themed music)

  • Pumpkin Powerlifting (yes, real pumpkins instead of barbells)

  • Spooky Spin (glow-in-the-dark spin classes)

 

Gyms like PureGym, The Gym Group, and F45 often run limited Halloween sessions — check local listings or social pages for details.


 7. Themed Charity Bootcamps & Fitness Challenges

Many local personal trainers and bootcamp instructors hold special Halloween bootcamps — often outdoors, in parks, or even cemeteries (yes, really).


Expect things like:

 

  • “Survive the Night” challenges

  • Glow-stick obstacle courses

  • Team games with creepy music or fake zombie chases


8. Indoor Halloween Sport Activities

Maybe you’re not a runner — that’s fine. There are loads of halloween sport activities that keep you indoors but still get your heart rate up.

 

Ideas include:

 

  • Halloween climbing sessions (many indoor walls decorate with webs and lights)

  • Haunted spin classes (music and lighting effects)

  • Costume-friendly CrossFit WODs

  • Halloween hot yoga — think candlelight, eerie playlists, and post-workout pumpkin smoothies

 

These events usually encourage dressing up — but keep your halloween gym costume practical. Breathable fabrics and quick-dry materials like Fittux activewear are ideal so you don’t overheat mid-session.

 

9. Virtual Halloween Fitness Challenges

If you prefer solo workouts or can’t make it to an in-person event, virtual challenges are another fun option. Apps like Race At Your Pace and MyRace often run special Halloween virtual runs — complete a set distance anytime during October, submit your time, and receive a themed medal.


It’s a simple, low-stress way to stay accountable and celebrate Halloween wherever you are.


10. Halloween Gym Costume Ideas for 2025

Choosing the right outfit can make or break your Halloween workout. You want something that feels fun but also performs.


Here are a few creative, fitness-friendly ideas:

Theme

Description

Outfit Tips

Vampire Athlete

Sleek black activewear, fake fangs, and a red cape

Use moisture-wicking fabrics; lightweight cape or detachable accessory

Zombie Gym Bro

Ripped tee, distressed shorts, pale makeup

Pick old gym clothes you don’t mind getting messy

Skeleton Runner

Black base layer with glow-in-the-dark bone print

Easy to DIY with reflective tape

Pumpkin Powerlifter

For the best effect, choose performance fabrics that breathe, stretch, and don’t trap sweat. If your costume limits your movement, it’s not worth it — remember, comfort and safety first.

 

11. What to Bring to a Halloween Fitness Event

Packing right makes a difference — especially for night runs or themed classes.


Checklist:

 

  • Headtorch or glow accessories (for outdoor events)

  • Water bottle or Fittux protein shaker

  • Lightweight jacket (UK autumn weather can surprise you)

  • Change of clothes if your costume includes makeup or fake blood

  • Small towel and deodorant for post-event socials

 

12. Why You Should Try a Halloween Fitness Event

Aside from the obvious fun, there are real benefits:

 

  • Breaks routine: Injects excitement into regular training.

  • Builds community: Meet new people through themed workouts.

  • Improves consistency: Events give you a reason to stay active through autumn.

  • Creates memories: Fun costumes and photos make fitness feel less like work.

 

And when you look back on your year, it’s these experiences — the night runs, the laughter, the messy pumpkin bootcamps — that stand out far more than solo gym sessions.
