Bobs Worth, the 11-4 favourite ridden by Barry Geraghty, has won horse racing's famous Gold Cup at the Cheltenham Festival.
Sir Des Champs, ridden by AP McCoy, was second at 4-1, followed by 7-2 Long Run, ridden by Sam Waley-Cohen.
Tony McCoy will take the ride on Sir Des Champs in the Betfred Cheltenham Gold Cup. His intended mount Sunnyhillboy was declared a late non-runner by trainer Jonjo O'Neill.
Bobs Worth is favourite to win the Betfred Cheltenham Gold Cup - followed by Sir Des Champs and Silviniaco Conti.
The Nicky Henderson-trained eight-year-old, to be ridden by Barry Geraghty, has not been seen since December when he emerged an outstanding winner of the Hennessy Gold Cup at Newbury.
Henderson is also represented by the 2011 Gold Cup winner Long Run, who claimed the William Hill King George VI Chase at Kempton on Boxing Day.
Paul Nicholls will have high hopes for Silviniaco Conti, who is unbeaten in three starts this season and was particularly impressive in the Betfair Chase at Haydock in November.
Davy Russell will miss the ride aboard Sir Des Champs in the Betfred Cheltenham Gold Cup after suffering a punctured lung.
The rider took a crashing fall from Un Beau Matin at the final flight in Wednesday's Coral Cup but was fit enough to take up his first two mounts on Thursday's card.
However, after finishing unplaced on both Argocat in the Jewson Novices' Chase and Stonemaster in the Pertemps Final, Russell was ruled out for the rest of the meeting.
The jockey has ridden Sir Des Champs on his last six outings, including his Irish Hennessy win.
ITV weather presenter Lucy Verasamy has details of what the weather has in store for the Cheltenham Gold Cup:
A test flight for Paddy Power's first light aircraft - a 63ft high balloon in the form of a giant pair of flying green Y-fronts - has been successful.
A Paddy Power spokesman said: "Our flying y-fronts provide an unrivalled view of the action for punters, as well as hopefully giving anyone in the grandstand a sight to remember and a bit of Irish luck“.
Further special appearances and flights are planned at major sporting events throughout the year.
