Charlotte Dujardin will be on the trail of double Olympic gold at Greenwich Park today as British equestrian's successful London 2012 campaign targets a rip-roaring finish.

To the strains of Land of Hope and Glory and Big Ben's chimes, 27-year-old Enfield-born Dujardin will conclude the dressage individual freestyle to music competition.

She set a British record with her patriotic routine when she gave it a trial run at Hartpury in Gloucestershire last month, and she starts today as gold medal favourite.

Her biggest challengers could be team gold medal-winning British colleagues, Barnet-born Carl Hester and Laura Bechtolsheimer, although Dutch star Adelinde Cornelissen and Germany's Helen Langehanenberg are waiting to pounce.
