He's obviously out of this grade now," Gollan said.
"He's getting right up in the weights although sprinters can obviously carry a bit of weight over the shorter distances.
"There's probably not a whole lot of him through the winter up here, so whether we maybe look to extend his prep down south, I'm not too sure.
"Maybe some short 1000-metre or 1100-metre races might suit him, but I just want to have a little think before we make any concrete plans."
Golden Boom's win in the Goldmarket delivered Gollan's fifth win in the past seven editions of the race.
