Denman finished second in the 2009 Gold Cup behind Kauto Star
Denman, one of Britain's leading racehorses, has had the new extension at Exeter Racecourse named after him.
The 2008 Cheltenham Gold Cup winner spent Tuesday at the racecourse as the site's brand new £2m stand was officially unveiled to the public.
The gelding, trained by Paul Nicholls at Ditcheat, also completed a leisurely circuit of the track where he won his first novice race in October 2006.
He has won 13 of his 17 races and is favourite for the 2010 Grand National.
Now aged nine, Denman is owned by Paul Barber and Harry Findlay. He won the Cheltenham Gold Cup in 2008, when he memorably defeated stablemate Kauto Star under a strong ride from Welsh jockey Sam Thomas.
He has had two seconds and a fall since then, and his next major engagement is likely to be the Hennessy Gold Cup at Newbury on 28 November.
Nicholls said of the star chaser: "He did a great piece of work on Saturday when we really put the gun to his head but that will have done him a lot of good too.
"He is a character - he is never a fantastic work horse - but we know where he is by the amount of work he has done at home and he's tightening up and really picked up coming down the home straight.
"We brought him here two years ago before the Hennessy, and all being well, he'll go there, then the Lexus in Ireland."
