As many as five winners of Grade One races, jumping’s highest class, could be set to clash in a mouthwatering renewal of Huntingdon’s showpiece race, the Trustatrader Peterborough Chase on Sunday.

They include the winner of the race two years ago, and three from Ireland amongst 8 entries for the £75,000 contest.

The Trustatrader Peterborough Chase, over two and half miles is due off at 1.55pm on a card which carries more than £160,000 in prize money.

First Flow, now aged 11, became trainer Kim Bailey’s second winner of the race when becoming the longest priced winner for a decade when a 12-1 shot two years ago. He must race right-handed and warmed up with a second place on seasonal reappearance at Ascot early last month.

Although Jair du Cochet won the race for France in 2003, there has, perhaps surprisingly, never been an Irish trained winner but the three possible pilgrims for Sunday’s race all look to have major chances if they make the trip to Cambridgeshire.

Trainer Joseph O’Brien’s pair, Banbridge and Fakir D’Oudaries have both landed Grade 1 races at Aintree, while Janadil, in the care of all conquering trainer Wille Mullins won the famous Fairyhouse Gold Cup in 2021.

They may face the formidable Edwardstone. Trainer Alan King’s stable star won two Grade One’s last year and no decision has been made as to whether he runs or takes his chance in Saturday’s Tingle Creek Chase at Sandown.

The team that won the race a year ago with Pic D’Orhy - owner Mrs Johnny de la Hey, trainer Paul Nicholls and jockey Harry Cobden - rely on Solo, who was second in the Betway Haldon Gold Cup at Exeter on his only start this season.

The possibles are completed by horses that finished first and third in the Old Roan Chase at Aintree last month. Jetoile caused a 25-1 shock when successful that day, and the 8-year-old would be a first runner in the race for Herefordshire trainer Ryan Potter, while Al Dancer, third that day, may travel from the Welsh yard of trainer Sam Thomas.
