Stable companions Dinoblue and last year’s winner Allegorie De Vassy head the BBA Ireland Limited Opera Hat Mares Chase at Naas this Saturday, on a card that is likely to provide racegoers with strong pointers to some major races this spring.

Grade 1 winner Dinoblue is the mount of JP McManus’ retained jockey Mark Walsh while Paul Townend will once again be onboard Allegorie De Vassy with both horses likely to have the Cheltenham Festival on their agenda after this weekend.
