The Terry Biddlecombe Challenge Trophy was a Grade 2 National Hunt chase in England which was open to horses aged five years or older.
It was run at Wincanton over a distance of 2 miles and 5 furlongs (4,224 metres), and was scheduled to take place each year in November.
It was won by some of the great names in steeplechasing during the eighties, but the races were often uncompetitive with the winner starting long odds-on.
The race was awarded Grade 2 status in 1990, and the following year was renamed the Desert Orchid South Western Pattern Chase.
There is still a race at Wincanton, now sponsored, where the winning owner receives the Desert Orchid Silver Cup.
