Zara Phillips will turn her attention to capturing gold at the 2008 Olympics after her stunning three-day eventing victory at the World Equestrian Games.
The Queen is said to be "very pleased" with Phillips' success
The 25-year-old, daughter of the Princess Royal, is the first British winner of the competition for 20 years.
"Obviously winning the Olympics has been a massive dream," she told BBC Radio Four.
"But you have to get everything right leading up to it, and have the horse power, so it's still a long way away."
Phillips is wary of looking too far ahead after seeing her hopes of competing at the 2004 Games ruined by an injury to her horse Toytown.
However, she and Toytown made up for that disappointment by adding the world title to the European crown they already hold.

"It's incredible, it's beyond my wildest dreams," she said.
"I'm just so privileged to have been in the team and had the opportunity to ride. It was just amazing."
Phillips said her parents - Princess Anne and Captain Mark Phillips - were both "excited and nervous all at the same time".
Asked for the Queen's reaction to her triumph, a spokesman for the Royal Family said: "I am sure she would be very pleased for Zara's success."
