As Snowfall's snow white record falls in Paris, there's a new favourite for the French Group 1 centrepiece as an Irish raider comes back into the reckoning.
Dermot Weld's mare Tarnawa didn't even have to win her last race in the Irish Champion Stakes at Leopardstown to gain favouritism for the Arc.
A contentious duel with AP O'Brien's star St Mark's Basilica saw the Aga Khan owned Tarnawa carried over by Ryan Moore on the Ballydoyle colt with only three-quarters of a length separating the pair at the line.
A stewards' inquiry went the way of St Mark's Basilica but that run and her five previous victories have convinced bookies that Weld's Irish raider is the one to beat.
Second and third favourites: Adayar and Hurricane Lane.
Godolphin stars Adayar and Hurricane Lane are nipping at the heels of Tarnawa for favouritism.
Adayar missed his prep run in the Prix Niel due to a leg infection and instead goes to Paris as Planet Sport Bet second favourite on the basis of his Epsom Derby win and a follow up victory in the King George VI And Queen Elizabeth Qipco Stakes.
Planet Sport Bet third favourite, Hurricane Lane, the winner of the St Leger, is doing everything right and goes to France on a hat-trick of wins.
The boys in blue have two Frankel colts in ripe form and after shifting from 7/1 to 9/2 with Planet Sport Bet, Hurricane Lane could even shift Tarnawa at the head of the betting before October.
Fourth favourite: Snowfall
AP O'Brien's ice cool filly Snowfall showed a touch of thawing in the Prix Vermeille with the 1/5 favourite being beaten by Roger Varian outsider Teona.
Anyone expecting a simple Arc prep for Snowfall were to be disappointed as the three year-old just didn't show the requisite finishing speed needed to see out the Arc.
Second was no disgrace, but defeat to Teona, who had finished tenth in Snowfall's Oaks win has put a slight incline in the way of the filly's snowball success.
That said, O'Brien has the skills to put Snowfall back on track for the big one, so the increasing price may well be a bonus for those who keep the faith.
