Trainer Gary Moore has likened champion chaser Sire De Grugy to the world's fastest man, Usain Bolt.
Sire De Grugy won at Chepstow recently in preparation for the Cheltenham Festival, where he is defending his Queen Mother Champion Chase crown.
Moore said the nine-year-old has proven his strength after recovering from a season-threatening hip injury.
"If he was a human, he would be Usain Bolt - he's big, strong and just very talented," he told BBC Sussex.
Moore, whose son Jamie rode Sire De Grugy to a six-length win at Cheltenham 12 months ago, believes the French-bred gelding will run even better to repeat last year's Ladies Day triumph.
Sprinter Sacre, the 2013 Queen Mother Champion Chase winner, and seven-year-old Tingle Creek Chase winner Dodging Bullets are among the favourites for next week's race.
"It is a slightly stronger race this year," Moore said.
"At least he proved he can handle the track, which is a big bonus. They have him to beat."
The Cisswood-based trainer believes the injury has turned into a positive for Sire De Grugy, whose win at Chepstow came after he failed to to finish in his comeback race at Newbury on 7 February.
"He has had a messed up preparation and it has probably cost him winning two or three other races," he added.
"He hasn't had the preparation he had last year, but he will go there a fresher horse, with four races less than what he had last year, so hopefully that will be a blessing in disguise.
"He is in good order and that is the main thing."
