John Inverdale introduces highlights of the opening World Cup rowing regatta in Serbia. It is the first of three World Cup events that Great Britain will use to fine-tune their preparations for the London Olympics, where Team GB are tipped to beat their Beijing medal haul of six. Double sculls pair Katherine Grainger and Anna Watkins were unbeaten together in 2011, and will be determined to extend that record in Belgrade. All eyes will also be on GB's new-look men's coxless four, which has been bolstered by the addition of Pete Reed and Andy Triggs Hodge.
