Twelve of the world’s top riders have been invited to take part in the competition which Ryan Moore has won twice, in 2009 and 2010.
Moore regards himself as an outsider this time around but will have reason to celebrate as he has been named Longines World’s Best Jockey.
“I think I have one with a chance but overall I am a long shot for Wednesday night, but I am hoping for a good evening,” he said.
Richard Hughes is delighted to be involved and has hopes for two of his mounts.
“You can never tell around Happy Valley, but I have got a couple of nice rides so we’ll see. I am looking forward to it,” he said.
France’s top jockey Christophe Soumillon is a strong fancy to take the prize he won 10 years ago.
“I have got a chance in the second leg and I ride a horse for Casper Fownes in the last leg with a live chance,” he said.
Among the other riders taking part are former winners Kerrin McEvoy (2013) and Joao Moreira (2012).
