Picturesque Boughton House is to be turned into a mudbath when a popular American endurance event comes to the country for the first time.
Tough Mudder, a gruelling challenge which tests people on a 12-mile obstacle course will take place at the Grade I listed house in May.
It is the only Midlands based event of its kind this year.
Fourteen events last year in America attracted about 150,000 participants and up to 20,000 people at each event.
The event champions teamwork and participants will have to navigate 12ft walls, muddy water, go through 4ft flames and into ice cold water.
A spokesman for the event said: “Events in the UK kick off in Northamptonshire in May, followed by one in Scotland in July and one in the North West in November.
“The Northamptonshire event in May will be a baptism of fire for competitors.
“They will have to negotiate pits of stinging nettles, waist high swamps, claustrophobic tunnels, not to mention the 10,000 volts of electroshock therapy they will receive before they drag their weary limbs over the finishing line for a well-deserved pint of beer.
“That initial pint is then followed by a Tough Mudder post party where Mudders can then swap stories of their experiences over some food, drink and live music.”
There are only three Tough Mudder events scheduled for the UK next year.
The Boughton House challenge takes place on Saturday, May 12, and Sunday, May 13.
Entry is £80 for the Saturday event and £75 for the Sunday challenge with those prices remaining until February 29.
