Trainer Tom Lacey, based in Herefordshire, said today: "Kimberlite Candy has been in good form since Newcastle.
"He is in the Grade Two at Cheltenham and also has the option of the three-mile race at Doncaster on Saturday.
"He has been very impressive so far and you could not have asked for much more, but he is ground dependant. There is rain forecast so we will just have to see, although I haven't spoken to Mr McManus or Frank [Berry] yet.
"If he doesn't run this weekend, there is a race for him at the beginning of February."
The Neptune Investment Management Classic Novices' Hurdle has been a good pointer to The Festival in recent years, with Wichita Lineman (2007), Bobs Worth (2011) and At Fishers Cross (2013) going on to win the G1 Albert Bartlett Novices' Hurdle and Monsignor (2000) taking the G1 Neptune Investment Management Novices' Hurdle.
