Cheltenham Gold Cup winner Coneygree will not run again until next season, says assistant trainer Sara Bradstock.
Coneygree became the first novice to win the big race for 41 years when he won by a length and a half on Friday.
The eight-year-old could now bid to emulate Denman by adding the Hennessy Gold Cup at Newbury in November.
Bradstock told BBC Radio 5 live's Sportsweek the horse's owners turned down an offer of more then £200,000 for Coneygree as a novice hurdler.
Wife of trainer Mark Bradstock and daughter of Coneygree's breeder - the late Lord Oaksey - she praised the owners for staying loyal to their small yard.
"I don't have any great ambitions to have 200 horses like the big battalions," she said.
"We've always done very well with limited horses but hopefully this will put us into the limelight and we'll get some more horses."
