THE world’s best racehorse, Hong Kong’s Ka Ying Rising, returned to action with a blistering win in the Group 3 HKSAR Chief Executive’s Cup Handicap over six furlongs last Sunday.

David Hayes’ sprinter shattered Sha Tin’s six-furlong track record for the fifth time before entering quarantine in preparation for a defence of the Group 1 The Everest in Sydney, Australia next month.
