“It is like building a town.” That was how the organiser of the CLA Game Fair described the mammoth task of putting on the July 22 to 24 event.

About 140,000 people are expected to attend the fair, which will feature exhibits and displays of shooting, archery, quad biking, falconry and more.

And the fair, which is held every three years at Blenheim Palace, in Woodstock, is expected to generate £13m for Oxfordshire’s economy.

The event is organised by the Country Land and Business Association (CLA) and work at the 500-acre site has been going on since early June.

Director of marketing and show development Fiona Eastman said: “We are turning a green field into a massive show.

“Between the show site and the caravan park, it is like putting the infrastructure in for a small town.

The task ahead of the organisers is massive, and, by the opening of the fair, more than 1,000 contractors will have worked on its construction.

Some 55,000 square metres of tents will be erected by the organisers – with more supplied by the individual exhibitors.

There will be 11 bars, four restaurants, four hospitality suites, four Pimm’s units, three Champagne bars and 20 ice-cream vans.

And, on top of that, there will be a further 70 mobile catering units across the site.

In the CLA members’ enclosure alone, 500 Bottles of Champagne and 6,200 pints of Pimm’s will be drunk, with 400 kilograms of ice used.

At lunchtime, the members look set to devour 450 dressed crabs and, at breakfast, 8,000 rashers of bacon.

One of the largest tasks is to lay six miles of water pipes, to pump water into the field for everything from toilet blocks to dog bowls.

For every hour of the fair, 22,000 gallons of water will be pumped into the site. About 600,000 gallons will be used in total.

More than 40 generators will be used to power the exhibits – enough power to service 1,600 family homes.

On top of this, organisers will put up four miles of fencing around the site, lay 20 miles of cabling and install 1,800 individual sockets.

Some 6,000 people will stay overnight during the fair, and a caravan park is expected to be packed with 2,250 caravans and tents.

About 61,000 cars are expected to be parked in the car parks over the three days.

But although Ms Eastman said this year faced new challenges, including boosting the signal of smart phones, she was looking forward to it.

She said: “There is nothing like the adrenaline rush of the Friday morning, when the show opens and it all comes alive.

“The atmosphere at the game fair is fantastic – it is the Glastonbury or Woodstock of the countryside.”

The Game Fair is open from 9.30am to 6pm daily with a special late night on July 22 until 7.30pm. However the gates open at 6.30am on Friday and 7am at the weekend.

On-gate adult tickets vary in price from £24 to £29, family tickets start at £56 and under 10s go free.
