Tina Cook helped Britain's eventing team to a silver medal in the Olympics at Greenwich Park today.

A sparkling clear round by the Findon rider on Miners Frolic guaranteed second place for the GB quintet behind Germany.

One time fault left Cook in fourth place as she went into the afternoon's individual event and in the hunt to medal again in the final round of showjumping.

But after knocking down two fences, she ended in sixth place. 

Cook and Miners Frolic won individual and team bronze in Beijing four years ago.
