ENGLISH superhorse Frankel stretched his unbeaten run to 13 with an impressive win in the Juddmonte International Stakes at York.
The racehorse, regarded by many as a challenger to Australia's Black Caviar as the world's best, cruised to a seven length win
It was the first time Frankel had stepped up to race over 10 furlongs but he handled the journey with ease. All of Frankel's wins to date have come over distances up to a mile (1600m), but this race was over 2100m.
