The countdown is continuing to a major endurance challenge being staged at Harewood House in Leeds.
Thousands of people are expected to take part in the Adrenaline Rush race in the stunning grounds of the stately home on Saturday, October 17.
And today organisers said people should sign up as quickly as possible if they want to make sure of a place in the eagerly-awaited event.
Graham Anderson, a director at Inmotion Sport, told the Yorkshire Evening Post: “The Adrenaline Rush Leeds promises to be the best yet.
“It will be tough but a lot of fun. The event is filling up fast, so anyone wanting to experience the thrills and spills of the Adrenaline Rush should sign up straight away.
“If you love a physical challenge and a muddy day out then this is right up your street.”
Adrenaline Rush participants will be able to tackle one of three different course lengths – 5km, 10km and half-marathon.
They will all feature a range of nerve-jangling obstacles, each of which has a suitably fearsome sounding name.
Pitlane Hell, Water Torture, Dead Weight and Bungee Time are among those that could confront the racers at Harewood House.
Macmillan Cancer Support will be one of the beneficiaries of the Adrenaline Rush’s visit to Leeds, with 25 per cent of each entry fee going directly to the charity.
