Sheffield's English Institute of Sports will be the star-studded venue as British Judo's Olympic hopefuls hit the mat in an attempt to earn a tilt at medal glory in London 2012.
For fans the event represents the unique and hugely intriguing opportunity to witness international team-mates squaring up in a high stakes environment.
Among those joining the fray will be Euan Burton, Karina Bryant, Sarah Clark, a returning Craig Fallon and fellow 60kg star Ashley McKenzie, Sophie Cox, Winston Gordon and youngsters Gemma Howell and Kelly Edwards.
There are mouth-watering clashes in prospect as former world champion Fallon could meet reigning U23 European champion McKenzie for the first time while Bryant will feature in an under 78kg field featuring the fast-rising Sarah Adlington.
The talented duo of Gemma Gibbons and Sally Conway will contest an absorbing under 70kg category.
Several young players will see action in the senior competition as the highly-regarded Lewis Keeble, Owen Livesey, Louise Little, Samantha Clark and Sarah Biles take on the cream of the British crop.
The outcome of these battles will give more than a hint of who could line-up as part of the British Olympic team in London next year.
On the Saturday Britain's brightest young judoka will take to the mat at the under-20 Trials.
Among a line-up brimming with promising talents and long-time GB junior internationals, will be emerging names such as 2010 BJA Young Referee of the Year Natasha Maslen, sisters Amy and Becky Livesey, Conall McGregor and Lucy Renshall.
The eagerly-anticipated event will also be streamed lived on the British Judo homepage from approximately 10am each day and will feature two of the four mats at any one time.
