If ENVOI ALLEN runs in the Supreme instead of the Ballymore having traded for absolute £1000s ......

Yes, looks like the Supreme.

Something needs to be done ?

They have always said if the ground came up soft or heavy they may switch

I thought trainer stated if there was "heavy" in the description of the ground. Anyway, a kick-in-the-teeth for antepost backers. But, thank-goodness for its short price and nrnb not many "victims".

think he will line up in ballymore

Nothing new here.

Racing Post 20 February:
Elliott, who mentioned a possible switch to the Sky Bet Supreme Novices' Hurdle if the ground came up heavy at Cheltenham

RTE 18 February:
The trainer said: "If the ground came up heavy, I wouldn't rule out him running in the Supreme, but at the moment he'll go in the Ballymore.

Wen did the cheltenham going ever come up heavy ?
Its not allowed under bha rules and an instant sacking for bob and simon
Your best bet is HEAVY IN PLACES
Which will be supported by going stick readings grom under the trees down the far side
These groundsmen are top professionals, camt have heavy in the description over 20% wont turn up.

Yes irishone a bit of a farce really back in 2014 for good reason I bet the ground for the opening race to be good,however Cheltenham called the official going as good to soft ,Timeform called it good to firm.

Currently 4/7 to run in The Ballymore and 5/4 to run in the Supreme.
