The world's biggest bouncy castle is coming to London. The 893ft-long inflatable, known as 'The Beast' was created with one simple aim - to give adults the chance to be a kid again.

It's the length of more than two football pitches and anyone brave enough to try it out faces a tiring race to the finish as they take on a challenging course of inflatable walls, rings and bouncy balls.

Benedikt De Vreese, owner of V-Formation, the company that custom made The Beast, said:

People are dead tired when they slide the last piece of the track but after that they can’t stop talking about how cool it was. That’s why we built this, to create something special for adults but where they can be a kid again. It’s not always about power or speed, it’s about endurance and knowing yourself.

'The Beast' is heading to Hyde Park in London in 2017, where they will challenge contestants to become the fastest person to complete the course.
