Michael Dickinson, who saddled the first five home in the 1983 Cheltenham Gold Cup, has decided to retire.
Dickinson will always be remembered for the 1983 Gold Cup
Dickinson, 57, hopes to have moved on most of his horses by the middle of December to concentrate on his all-weather surface business in the US.
"I need 100% of my time to concentrate on Tapeta Footings," he said.
"I spent most of last winter overseas and 50% of my time this summer visiting Tapeta installations in five countries, which leaves little time for training."
As a rider and trainer, Dickinson has a total of 1,312 races on both sides of the Atlantic.
"In the United Kingdom, I am most proud of being champion jumps trainer three times and of winning the Racing Post's award for the Greatest Training Feat," he said.
"In America, I am most proud of being runner-up in the Eclipse Leading Trainer Award, to have received the C.V Whitney Award of Special Achievement and of building Tapeta Farm, from which I sent out eight Grade One winners in the first eight years."
Dickinson's remarkable first five in the 1983 Cheltenham Gold Cup has gone down in racing folklore.
Aged just 33 at the time, Dickinson reportedly lost a stone in weight in the build-up to the race because of the pressure of trying to keep five mounts in prime condition.
But Bregawn, Captain John, Wayward Lad, Silver Buck and Ashley House filled the main places to make all his efforts worthwhile.
Even before then, he already had an impressive reputation, having sent out a record 12 winners on Boxing Day in 1982.
When he accepted an invitation from Robert Sangster to be his private trainer, it looked like a dream partnership, but it never worked out and they went their separate ways in 1986, when Dickinson decided to try his luck in America.
After nearly a decade of success, in 1998 he opened his own Tapeta Farm, and since then he has become more involved in developing the Tapeta surface as an alternative to riding on dirt.
"I have been concerned for sometime about the welfare of horses racing on unsuitable surfaces and really want to repay the horse in my own small way," he said.
The surface has been put down successfully at Godolphin's Dubai stables and also the Golden Gates track in California.
