London 2012 organisers have announced ticket details ahead of the mountain bike test event at Hadleigh Farm, Essex on July 31, 2011.

The Hadleigh Farm International, which will have a 5,000 capacity, is one of four ticketed events in the London Prepares series, along with beach volleyball, basketball and BMX.

Tickets will cost between £10 and £20 and will go on sale through Ticketmaster from May 26, by using a visa card only.

Bikemagic revealed in March, when the cross-country race track was completed, that approximately 100 of the world’s top riders, from 40-50 countries, will take part in July’s dress rehearsal.

And the test event series will also allow organisers to fine-tune their preparations ahead of the women’s Olympic cross-country race on August 11, 2012 and the men’s showdown 24 hours later.

“The London Prepares series is essentially about putting our plans into practice,” said London 2012 chairman Paul Deighton.

“These events are our opportunity to try out our new venues, test new technology and equipment and walk our extended teams through their roles and responsibilities.

“We have learned a lot from previous Games’ which we will put to good use as we challenge ourselves over the next 12 months.”

London 2012’s initial ticket sale ended on April 26, with applicants set to find out whether they have been successful next month. Unsold tickets will go on sale again next year.

Deighton added: “Although our venues won’t be dressed in their Games finery, a number of events will give the public a chance to see some world class sporting action ahead of next year.”
