The Moonee Valley Racing Club will host a trackwork session on Tuesday morning from 6.30am featuring several Cox Plate-bound horses, as well as a host of others nominated to race on Manikato Stakes night on Friday or Cox Plate day the following day.

The final field for Saturday's weight-for-age Cox Plate will be announced after 8.30am.
