Ground conditions will decide month whether Stradivarius defends his Qipco British Champions Long Distance Cup title at Ascot.
Trainer John Gosden has stressed the five-year-old will only line up at the Group 2 contest on October 19 in the event the ground is not overly soft.
Sea The Stars' boy procured a Weatherbys Hamilton Stayers' Million bonus out last time when adding in the Lonsdale Cup in York to victories at the Yorkshire Cup, Ascot Gold Cup and also Goodwood Cup.
Gosden said:"I would think that Champions Day is quite probable.
"If we got a lot of rain and it'd move heavy, that are the one thing that would probably stop us operating.
"He's a terrific activity and he is probably happiest along with the floor. The good to delicate and softish ground was managed by him, but I'd be worried about earth.
Having seen his winning sequence is extended by Stradivarius to nine to the Knavesmire on his latest start, Gosden reports the gifted stayer to have come from the race in good shape.
Gosden included:"He is in tremendous form as the race. He is bucking and playing out and using a shout which he likes to do.
"He always tells you when he's about. For a little man he makes a lot of noise"
Looking past Qipco British Champions' Day, the Newmarket handler insists that a decision if stays in training next year is going to be reached by his owner Bjorn Nielsen.
Gosden included:"It's very much up to Mr Nielsen whether he would like to keep him in practice a year ago and I will leave that entirely to him.
"The horse is vociferous to let us know what he thinks."
