This September, Sofia Is Getting a Completely Different Kind of “Run”
At first glance, it looks more like a giant playground than a running event.
Huge inflatable obstacles.
Massive slides.
People jumping, climbing, crawling — and probably falling over more than once.
And a lot of laughing.
But that is exactly the point.
👉 On September 12, 2026, a completely different obstacle experience is coming to Sofia.
And this time, you don’t have to be an athlete to take part.
No Timing. No Pressure. No Need to Be Fit.
Forget about personal bests.
Forget about running watches.
Forget about finishing first.
Here, the goal is much simpler:
✔ Jump
✔ Slide
✔ Climb
✔ Crawl
✔ Laugh
And do it together with your friends, colleagues — or your kids.
What Is the Inflatable Run?
Think obstacle course.
Then replace the mud, extreme physical challenges and intimidating walls with giant inflatable obstacles, slides, tunnels, climbing sections and fun movement challenges.
The result is an obstacle experience designed for ordinary people.
Not professional athletes.
Not hardcore runners.
Everyone.
You can walk between the obstacles.
You can run.
You can stop and take pictures.
You can help your kids over an obstacle.
And if you want to go around again — you can.
No competition. No stress. Just a shared experience.
Finally, an Obstacle Event the Whole Family Can Do Together
For years, one of the questions we hear most often at Legion Run has been:
“Can my kids participate with me?”
This event is our answer.
Parents and children can take on the course together.
You climb together.
You slide together.
You fall together.
You laugh together.
And that’s exactly what makes this different from a normal running event.
You Definitely Don’t Need to Train for This
One of the biggest misconceptions about obstacle events is that you need to be extremely fit.
Not here.
👉 You don’t need to be a runner.
👉 You don’t need obstacle-race experience.
👉 You don’t need weeks of training.
👉 You don’t need to take yourself too seriously.
The course is designed around fun and movement rather than performance.
Some people will run it.
Others will walk.
Some children will probably want to do the same obstacle three times.
That’s fine too.
Giant Obstacles. One Big Playground.
The course will feature a series of massive inflatable obstacles combining different types of movement:
🔥 Climbing
🔥 Sliding
🔥 Crawling
🔥 Jumping
🔥 Balancing
🔥 Running
The obstacles are positioned along a course that can be completed in multiple laps during your allocated session.
That means this isn’t about crossing a finish line as quickly as possible.
It’s about how much fun you can fit into the experience.
Created by the Team Behind Legion Run
The event comes from Legion Run, the obstacle event brand that has organized events across Southeast Europe for more than a decade.
But this is deliberately a different experience.
Legion Run challenges you.
The Inflatable Run is designed to make you move, play and have fun together.
After years of seeing spectators, families and younger participants asking for a format they could experience together, we decided to build one.
And now it’s coming to Bulgaria.
Event Details
📍 Sofia, Bulgaria
📅 September 12, 2026
🏃 Inflatable obstacle course
🎈 Giant inflatable obstacles
👨👩👧👦 Designed for children, adults, families and groups of friends
⏱️ Participants start in waves
🔄 Multiple laps possible during your session
🏋️ No specific fitness level required
🏆 No timing and no competition
Not Just for Families
Bringing the kids?
Perfect.
But you absolutely don’t need children to have an excuse to participate.
Come with:
👫 Your friends
👨👩👧👦 Your family
👩💼 Your colleagues
🎉 Your entire group
Because putting ten adults on a giant inflatable obstacle tends to make adults behave suspiciously like ten-year-olds.
And we’re completely fine with that.
More Than Just a Run
Around the course, expect the atmosphere of an event rather than a traditional race.
Music.
Food and drinks.
People cheering.
Friends taking pictures.
Families spending the day together.
And thousands of moments that will look significantly more graceful in your imagination than they do in the photos afterwards.
This Is Not Something You Watch
You could stand on the side and watch everyone else jump, climb and slide through giant inflatables.
But that would rather miss the point.
This isn’t something you watch.
It’s something you experience.
So on September 12, bring your kids.
Bring your friends.
Bring your colleagues.
Or just bring yourself.
Sofia is about to become one enormous inflatable playground.
