Double Olympic champion Charlotte Dujardin set a new world record as she won Grand Prix gold at the Olympia Horse Show in London.
Dujardin, who won two world titles in August and was fourth in the BBC’s Sports Personality of the Year, scored 87.740 for her routine with Valegro.
It beat the previous mark of 87.129, which the pair set at the World Cup final in Lyon in April.
“To break another world record is fantastic,” Dujardin told BBC Sport.
Valegro’s owner and fellow London 2012 team gold medallist Carl Hester came fourth with Nip Tuck, who he hopes will be his horse for the Rio Olympics in 2016.
The defending champions are targeting a second successive world record after completing the treble at last year’s event.
The year-ending Olympia event – officially known as the London International Horse Show – runs until Monday.
Motocross is a form of motorcycle racing on off-road circuits in all weather – a physically demanding sport.
