Charlton said the team had deliberately kept Athapascan on the fresh side for a tilt at Saturday's contest but gave the stayer a gallop between races at Warwick Farm last week while he wound up his preparation with a gallop on the Kensington track at Randwick on Tuesday.
"He hasn't done a lot since the Sydney Cup, so it was just a case of taking him to Warwick Farm for the day and giving him a hit-out," Charlton said.
"The Sydney Cup was our aim with him and once we got through that we didn't want to give him an extended period in the paddock, so he just had a freshen up.
"This was the most likely race with potential Melbourne Cup aspirations in the spring."
Ben Melham, who has been taking part in the Tour d'Horse, a charity event to race money for the KIDS Foundation in the Hunter Valley, will ride Athabascan on Saturday.
