It's arguably Happy Valley's biggest night of the year on the track, with 12 of the world's best riders in Hong Kong to compete for the Longines International Jockeys' Championship.

British champion Ryan Moore and Italian star Mirco Demuro ($3.70) head betting on the Jockey Challenge - which takes in races five through eight, the four races that make up the IJC - while Hong Kong's own Douglas Whyte ($7) and Zac Purton ($8.50) can both win the championship again.

The first race on a nine-race card is at 6:30pm.
