Greenwich arena is ready for the Olympics
The arena surface at Greenwich, which will host equestrian events, has been given the green light by the International Equestrian federation (FEI).
Last summer there were some complaints over the surface at the test event, with a number of showjumpers claiming it was "puddingy".
As a result the specification of the surface was altered and an assessment took place on the main stage.
Professor in equine functional anatomy at the Swedish University of Agricultural Sciences Lars Roepstorff also assessed the surface.
Secretary-general of the FEI Ingmar De Vos said it is the first time that there has been such a scientific approach to footing and hopefully this will stand the surface in good stead for the Olympics.
Sports director for the organisers Debbie Jevans added: "With support from the FEI, the contractors and our own team have done a great job to get the make-up of the surface right, and we believe this will be a world-class surface."
