Double Olympic dressage champion Charlotte Dujardin and her London 2012 horse Valegro could return to action next month.
The pair look set to be reunited competitively at Olympia's London International Horse Show a week before Christmas.
Nominations for entries will not be formally announced for another 12 days, but show organisers have confirmed that Dujardin and Valegro are to be among the submitted combinations.
Gloucestershire-based Dujardin made a dream Olympic debut at Greenwich Park in August.
She was part of Great Britain's gold medal-winning team alongside Carl Hester and Laura Bechtolsheimer, and then took the individual freestyle gold ahead of Holland's Adelinde Cornelissen and Bechtolsheimer.
Britain had never previously won an Olympic dressage medal, but 27-year-old Dujardin's double success continued her remarkable rise in the sport.
She became the world number one as a result and is also the current grand prix special world record-holder.
