Wow... this is one of the most unusual businesses I've come across!
This business is a 5 km (just over 3 miles) obstacle course. And you pay money to run it.
But that's not what's unusual about this business...
As you run the course... You are chased by
ZOMBIES!
That's right! It's good training for the upcoming zombie apocalypse!
It moves location across the country (the next one is in Pennsylvania, in September)...
I don't know who came up with this... But I hope it succeeds!
This is one of the weirdest (yet spookily fun) business ideas I've ever come across!
Here's their website...
