Paul Webber is set to give Cantlow an outing over hurdles at Ascot on Saturday ahead of the Cheltenham Festival.
The Banbury trainer wants to give the eight-year-old a run before next month's big meeting but is keen to protect his handicap mark over fences.
Cantlow was third in last season's Pertemps Handicap Hurdle Final at the March jamboree and is towards the head of the ante-post betting for both the JLT Speciality Handicap Chase and the Byrne Group Plate.
"He's in great form and he goes to Ascot on Saturday over hurdles to preserve his chase mark of 143 at the Festival," said Webber.
"I don't know which race he will go for there. I know he's favourite for the JLT, but I can imagine him going for the two-mile five (Byrne Plate), what we called the Mildmay, instead, a race my father won. I can't say which race it will be yet."
Cantlow was last seen in winning action at Taunton in a novice chase a month ago.
