Denman is back in full training for hunting and team chasing, following his life-threatening infection last year.
Rider Charlotte Alexander has been putting the 14-year-old through his paces and even sent him off for a session with eventer Mike Jackson.
“We did grids and poles and really just got Mike to see what we have got to work with,” she said.
And although you won’t be seeing him at an event any time soon, Mike thought Denman had potential.
“Mike rode him and said if he was a 4-year-old, he would be a Badminton horse,” added Charlotte.
“He thought Denman’s canter was great and there is a lot we can do to help him. I want to be able to jump gates and upright park railings out hunting.”
Denman also took part in a parade of ex-racehorses on the opening day of the Cheltenham Festival (11 March) with other former heroes, including his old stablemate Kauto Star.
“He was on fire at Cheltenham and loved galloping up the track ” said Charlotte.
“He is feeling very well at the moment and he knew he was back at Cheltenham. I really did have my hands full!”
