Longchamp is the venue for some top class flat racing on Sunday, and Betfair Ambassador Ryan Moore gives his exclusive thoughts on some of the Arc's supporting races...
If it remains soft then Mayson could be the one to beat if jumping and rolling on from stall one. Sometimes you can use up too much of your horse early on in those circumstances and he hasn't been seen since winning the July Cup, but he won that by five lengths and in that kind of form, in conditions that suit, is probably the one to beat. Spirit Quartz is clearly a big threat on his seconds to Ortensia at Goodwood and York, and if the ground dried out then Sole Power is a proven Group 1 horse.
I would love to see Purr Along win for William Muir and the formbook certainly suggests she has every chance. She made Certify battle hard for the win in the May Hill, the pair pulled 8 lengths clear and the winner followed up next time. But sometimes a well-bred, unexposed French horse comes up trumps in this and there are a couple of likely sorts in here. And actually the likes of Peace Burg doesn't have that much to find with Purr Along. Aidan has the knack of improving his two year olds throughout the season, so don't rule out Magical Dream. She built on her Moyglare fourth when winning a Group 3 at the Curragh last time and is going the right way.
This looks a very tight Group 1 and I don't have a strong opinion to be honest. The likes of Olympic Glory, What A Name and Pedro The Great are obvious candidates, but if the ground isn't too bad then don't rule out George Vancouver. I am not sure what went wrong with him last time but I rode him to finish second to reckless Abandon in the Morny and I liked him a lot. If it was 7f on good or better ground, I would be fancying him to run a big race. But I don't think he wants soft ground, and that is a very obvious drawback here.
Izzi Top probably ran the race of her life when second to Snow Fairy in the Romanet, with Galikova just ½ length behind in third and Giofra back in sixth. All three will have their supporters here, along with Rjwa - Giofra will be more at home here if it remains testing - but I just think Galikova is a fresh horse and could win this. She caught my eye when fifth in the Vermeille and takes in this race instead of the Arc. I think 1m2f on soft ground could be her optimum conditions.
