Brothers Phil and Nick Smith are launching an assault course for adults and children aged eight and over this weekend.
The Playground is a 1km course, based at Suffolk Academy, in Barrow, which features 25 obstacles including tyre runs, wooden walls, monkey bars, big ditches and a Ninja Warrior-style ramp.
Nick said: “We’ve worked hard for the past five months through all weathers so it’s both surreal and exciting that we’re now finally ready to open our doors - and ditches - to the public.
“We look forward to welcoming all ages and abilities to come along and have fun whilst getting fit.”
Archery Tag, a sports injury clinic and refreshments are also available on site.
A day pass will cost adults £10 and children £5.
