THE Prix de l'Arc de Triomphe is the race that stops a continent.
Worth a stonking £4.3million, Europe's richest race always throws up a top class winner.
And with it comes an absolute stack of cash for some of the top yards in the world.
This year's race over 1½ miles takes place at Longchamp on Sunday October 3 - and it looks to be an absolute stonker.
Epsom Oaks winner Snowfall was the runaway favourite but has now drifted massively after her shock defeat to Teona in Paris.
Meanwhile, Dermot Weld's Tarnawa has plummeted in price after finishing runner-up to St Mark's Basilica at the Irish Champions Weekend and is now into 11-4.
But Coral report there is a new favourite in the shape of Epsom Derby winner Adayar, who's gone into 5-2.
Coral's David Stevens said: "Adayar is currently attracting the most support for Sunday's big race, while Hurricane Lane has also been popular, but while the former has regained favouritism from Tarnawa, the Derby winner is by no means certain to start favourite, with the filly heading to Longchamp with plenty of her own backers."
Here, SunSport looks at the complete list of runners as it stands - and their latest odds from Coral.

Arc de Triomphe 2021 tips
SunSport tipster Templegate will bring you his tip before the race.
Dermot Weld certainly holds a very strong hand in Tarnawa, who lost nothing in defeat to St Mark's Basilica in the Irish Champion Stakes.
One to keep an eye on is Japanese horse Deep Bond, who has been slashed in price since seeing off Broome by just over a length in the Qatar Prix Foy.
The four-year-old has won £1,694,062 in just ten races.
