Stuart Edmunds is unsure how Maria's Benefit will cope if testing conditions prevail for the Trull House Stud Mares' Novices' Hurdle at Cheltenham on Thursday.
The six-year-old has won each of her five starts since being beaten on her hurdling debut at Worcester last September, most recently claiming a Grade Two prize at Doncaster in January.
Although she has since suffered a minor setback, Edmunds reports his star mare in fine form as she prepares to lead the British challenge against the Willie Mullins-trained Irish hotpot Laurina.
However, he admits only time will tell if she will prove as effective if the current soft ground remains.
Edmunds said: "I am slightly concerned about the ground, but the jockey (Ciaran Gethings) is not.
"She is 100 per cent and she will go there. She did her last three-quarters piece of work (on Saturday morning). She is very well and I couldn't be more happier with her.
"I think she is better on better ground, but the jockey said it won't bother her."
Maria's Benefit is a general 5-1 shot for her Festival assignment, with Laurina the 8-11 favourite.
