No beating around the bush, I'm banking on Enable winning her third Prix de l'Arc de Triomphe at the second attempt at 15:05.
Frankie Dettori won Europe's most valuable 12-furlong race on the mare in 2017 and again in 2018. The one downside is that she was a beaten favourite last year on similar going to what she will face this weekend.
But it is hard to nominate one to beat her in her current vein of form.
Her sole defeat this year came over 10 furlongs and she won her two subsequent races as comfortably as her odds-on price suggested she would. I would not have fancied her to win had Love been in the race but once Aidan O'Brien's filly was withdrawn she looks the likeliest winner.
The second and third favourites, Stradivarius and Persian King, are running over trips that will push them to their limits. Stradivarius hasn't the speed needed to win a Group 1 over 12 furlongs and is unlikely to come up with it now at the age of six. He was narrowly beaten in his prep race over course and distance and that was far from a strong renewal of the Prix Foy.
Persian King is a top-class miler that has been kept to that trip since finishing second to Scotsass in last year's French Derby. Surely he would have contested a race over 12 furlongs before now if Andre Fabre thought he truly had the stamina?
I love Persian King to bits and he has done us three big favours since racing resumed in May. But over a mile and four? No. I would go with a 12-furlong specialist like Enable every time.
So who will chase Enable home? Scotsass and Japan finished on her hooves last year in third and fourth respectively. At 8/1 and 14/1 there is a definite case for backing one, or both, each-way. I prefer Scotsass as he is the more consistent and won a Grade 1 this summer. Japan, on the other hand, has not won for a year and his usual rider Ryan Moore prefers his stablemate Mogul.
Stable jockeys often opt to ride a younger horse in peak form rather than a stale one that has run in the race before, has the tee-shirt and been found wanting. That sums up Japan perfectly whereas in winning the Juddmonte Grand Prix de Paris over course and distance from In Swoop, Gold Trip and the Derby winner Serpentine Mogul hit a new high and might - at a stretch - put it up to Enable.
He has to improve a fair bit but I think Moore has picked the right one of Aidan O'Brien's four. So It's Enable for me and Mogul each-way at 11/1 on the Sportsbook.
O'Brien two-year-old can hit the Mark
Two Group Ones for two-year-olds precede the Arc, one over seven furlongs and one over a mile.
Two Brits, two Irish and two French line up for the Prix Jean-Luc Lagardere for colts and fillies at 13:15.
It is a race in which favourites have a good record and no runner longer than 6-1 has won it in the last decade. Those trends, and form, point to St Mark's Basilica and Nando Parrado having the finish to themselves.
Both have been placed in Group 1s - St Mark's Basilica was third to Thunder Moon and Wembley in the National Stakes at the Curragh with top-class Lucky Vega fifth; Nando Parrado was runner-up to Campanelle at Deauville.
Ryan Moore's mount is the longer-priced of the two but a line through Lucky Vega gives him the edge. Laws Of Indices had an off-day behind St Mark's Basilica last time at the Curragh but beat him fair and square there in the Railway Stakes in the summer. You might want to consider Laws Of Indices at 10/1 but outsiders don't have a good record in the race.
Gorgeous can steal Beauty's Thunder
The Prix Marcel Boussac for fillies at 13:50 is expected to go to a raider rather than a local with Joseph O'Brien's Pretty Gorgeous 7/4 and Richard Fahey's Fev Rover 5/1. It is 8/1 bar.
Pretty Gorgeous has only raced in Ireland, most recently finishing a close second to Shale in the Group 1 Moyglare Stud Stakes over seven furlongs.
Fev Rover, a great buy at £20,000, made light work of the very soft going in a Group Two over six furlongs at Deauville last time, getting up late to beat Plainchant in a Group 2 with King's Harlequin a length back in third.
I should put in a good word for Ken Condon's runner Thunder Beauty as she was given a lot to do when two and a half lengths behind Pretty Gorgeous at the Curragh. She was last with three furlongs to go but was fifth at the line after making significant ground on the leaders in the straight. The extra furlong has to be good news, if you fancy her, as she has more stamina than speed in her pedigree.
There are worse each-way bets than Thunder Beauty at 10/1.
Tarnawa has plenty going for her
The first two home in the French Oaks, Fancy Blue and Alpine Star, take each other on again in the Prix de l'Opera at 15:50. There was just a short neck in it when Fancy Blue came out on top in July but the runner-up was not at her best that day.
That may have been because the 10 and a half furlongs at Chantilly was a tad too far for Alpine Star. Then again, it may be the way she was ridden.
Back over a mile at Deauville last time, Alpine Star ran Europe's top colt at that trip, Palace Pier, to three parts of a length at Deauville. Fancy Blue, in contrast, was a beaten favourite in the Group One Matron Stakes, never at any stage troubling the first two home, Champers Elysees and Peaceful.
Tarnawa and Tawkeel are unbeaten this season, winning seven races between them. The former is officially rated 4lb higher than Sheikh Hamdan's filly as a result of her latest success in the Prix Vermeille when she easily accounted for Laburnum and Grand Glory over a longer trip than today's.
Tawkeel can't be ruled out though, as she won a Group One at Chantilly in June by five lengths. Not many fillies win a top race by that kind of margin.
The drop back to 10 furlongs from 12 concerns me but at odds of 6/1 Tarnawa looks a good each-way bet.
Glass should prove too sharp for Abbaye rivals
With Baattash out of the Prix de l'Abbaye at 16:25, last year's winner Glass Slippers is a worthy favourite to gain back-to-back wins in the Group One sprint.
It was just as soft, and a more competitive contest, when she won 12 months ago. Some fillies are not as good at four as at three but her game success at the top level in Ireland last month allayed any fears that that might be the case.
The second, fifth and seventh at the Curragh - Keep Busy, Make A Challenge and Liberty Beach - take her on again but there is no reason to suppose they will turn the tables on the favourite given she is better still on the prevailing going.
Keep Busy strikes me as each-way value at 8/1 as her latest run was a career-best. She needs to do even better still, though, to avenge her defeat by Glass Slippers.
French should take the Foret
The Prix de la Foret at 16:55 is a race we won last year, thanks to the William Haggas-trained One Master.
Now six, she made her challenge a furlong out, passing the leader Speak In Colours and holding the persistent challenge of City Light.
A seven-furlong specialist, One Master has since been beaten three and a half lengths at the York Ebor meeting by Safe Voyage but that was not one of Tom Marquand's better rides. Safe Voyage made all and One Master could have finished closer if ridden differently. There shouldn't be a lot between them, so 3/1 One Master, 4/1 Safe Voyage is about right.
The Foret looked perfect for Godolphin's Pinatubo -- five from five over seven furlongs -- but the Boys In Blue are happy to rely on Earthlight. A winner of two Group Ones over six furlongs as a two-year-old, the Andre Fabre-trained colt stepped up to seven on his latest start here at Longchamp and won the Group Three Prix du Pin from his stablemate Tropbeau with a bit in hand.
He is lightly-raced, has won on heavy and is my pick.
Aidan O'Brien's 8/1 shot Lope Y Fernandez could sneak a place, just as he did in the Irish 2,000 Guineas and when second to Pinatubo at Deauville in the summer. Richard Fahey's handicapper Turbo Strike is way out of his depth. I can only assume he is in the line-up because he is owned by the sponsors.
