With just over a month to go until a vintage renewal of the Prix de l’Arc de Triomphe at Longchamp, several of the main protagonists have showed their hand at York and Deauville.

Snowfall dazzled in the Yorkshire Oaks and has hardened as favourite from 7/2 into 9/4. She left Wonderful Tonight eight lengths behind in her wake, albeit on unsuitably fast ground, leading bookmakers to push David Menuisier’s mare out to 12-1. Wonderful Tonight will be seen again in the Prix Foy and has Olivier Peslier for assistance, but she is beginning to look more like a 20-1 shot for the Arc and will do well to trouble Jerome Reynier’s gelding Skalleti in the Foy – who is ineligible for the Arc.

Juddmonte International winner Mishriff looks attractive at 12-1, particularly in light of John Gosden throwing cold water on a Breeders Cup bid at Del Mar. He looks more likely than not to run in the Arc ahead of the Champion Stakes but he has not seemed the most resolute 12-furlong horse, based on his effort in the King George against Adayar, best-priced at 9/2 for the Arc.

Tarnawa remains of interest at 6-1 with bet365 and faces a tough test of her credentials against Prix du Jockey Club and Eclipse Stakes winner St Mark’s Basilica at Leopardstown next month. St Mark’s Basilica is weak on the exchanges for the Arc with most counting on Snowfall to be Aidan O’Brien’s ace card for Longchamp in October.

Deauville did not set the world on fire in the context of the Arc, but it was pleasing for Jean-Claude Rouget that Raabihah bounced back to form over a suitable middle distance trip and was cut into 20-1 from 33-1. In the same ownership Hukum for Owen Burrows may tempt connections into a supplementary Arc entry if he wins well in the Grand Prix de Deauville this weekend.

Ebaiyra could only manage sixth in the Group One Jean Romanet and although the trainer has pointed out her lousy form at the Normandy track, she looks an unlikely runner now at 66-1 with William Hill.

Deep Bond will represent Japan in the Prix Foy on what looks a mouth-watering trials card on 12 September. The son of Kizuna may not look the most exciting Japanese raider on paper, but he is a Group Two winner over further and loves soft ground.

In a weaker renewal he would have been of more interest at 50-1 with bet365.
