Oliver Townend has withdrawn his horses from Britain's reserve list for the World Equestrian Games, which start at the end of September in Kentucky, USA.
The Shropshire-based Townend has decided instead to concentrate on preparing himself and his horses for next year and qualification for the London Olympics in 2012.
Townend, 27, said: "Next year is going to very important in terms of qualification for the Olympics and it is in everyone's interests here to prepare well over the coming winter. I want to start that preparation as soon as possible."
One of Townend's final competitions of this season will be next week at Burghley, where he will defend the title on board Carousel Quest, the grey who took him to glory 12 months ago.
It will be the only horse going to Burghley from the Townend yard. "I was going to take Ashdale Cruise Master as well but decided against that," said Townend, whose 2009 season saw him lift the Burghley and Badminton titles.
"He has done enough this season and it is far more important that he is rested. After all, he is going to be an important horse for me in the next couple of years.
"It was a huge achievement for the whole team to win at Burghley last year and it will be great to try and do it again with Carousel Quest.
"He is a true Burghley horse, who has had a relatively quiet season and I'm sure he will rise to the occasion."
